MG section problem

MG section problem

2010-05-13 by kluberrrrr

Hi everybody,

I'm quite desperate here, so I hope someone could help me a bit especially because I'm not very good in English and I'm not an electronic guy!
A couple of years ago I found a polysix which had the famous leak battery problem, so impossible to play on it.

I tried to repair the KLM 367 but with no success. 
Then i discovered the Jed's project

Today I've just finished to solder all the parts on the KLM-367A clone board.
I put the board back on my P6. Then I turned it on.

First, the programmer panel seems to work fine, Led button repond when I push them

BUT there is no sound at all. Just some attack sound, some 'blops'.

When I hold a key down, I can hear the note coming very slowly and fade out. Just like the LEd of the MG panel fading In and Out very slowly.

The Mg frequency, delay and level's knobs don't affect the modulation. Even if the modulation level is at 0, the sound is fully modulated

So I guess it's the MG section which seems to not work properly. It looks like it is stuck on a very slow frequency and there is no way to cut the modulation.
 

Also cutoff, resonance, eg int, keyboard track knobs don't seem to change the sound.

When I built the new Jed's PCB, I used from the old board the mask rom IC, the TC5514APL-3 IC, the two LM13600 ICs and the 2SA798

What do you think? Is it possible that one of the Ic is dead? Or does it look like the problem is deeper?

Please excuse my poor english !


Cheers!

Vincent

Hi Vincent,

Did you fix the two PCB errors noted here (#1 & #3):

<https://sites.google.com/site/jedjorgensen/klm367a/images/pcb-bugs-errors>Also,
did you calibrate the board following the build as per the service manual?

Re: MG section problem

2010-05-14 by kluberrrrr

Hi Jed,

first I'd like to thank you for what you did for the P6 itself and of course its users! Even if my P6 doesn't work yet I remain positive :)
I also appreciate you fast answer! thanks!

I fixed the R52 and R98 issues. I was hesitating by doing the last one ( lift the resistance 9 and cut the trace) I did it : unsoldering one leg of the R9 cut the trace and put a jumper between the CN 06 pin 02 and the unsoldered leg of the R09.

No more sound at all !Well, I can hear on the background the modulation if i put the gain  very high of the audio amp. The knobs on the MG panel remain unusable

Before to did the fix, I was able to hear the notes played through the modulation generator which went in and out very slowly in any MG mod ( vca vcf )with a very normal volume. I'm sure that the sound is modulate because I can follow the MG led with the fade of the sound

I don't have done the VR adjustments yet because I don't have any access to an oscilloscope. But I'm not sure it will change a lot. My first target is to have the sound back without the modulation on it  .

Should I put the R09 back and remove the jumper? and try something else? Or should I try to do the Don B. fix on the 368 board?

Could the problem on my P6 come from another part?

Cheers!

Vincent

Re: [PolySix] Re: MG section problem

2010-05-14 by Andrew Jury

Vincent,

First thing. Does the P6 do the same thing in Œmanual¹ mode. If you have
just constructed the board the SRAM will be in an unknown state and the
patches will play all sorts of odd sounds. If you have selected Œmanual¹
which is it just the MG section that doesn¹t work? Don¹t assume just because
it sounds like the MG is at fault this is the problem. Go through each of
the control knobs and write down which ones do not seem to do anything. If
you can summarize this then we might be able to work out what has gone
wrong. If you are really desperate and can¹t figure it then contact me
outside the forum and I might be able to help you (I am just over the Le
Manche). This is certainly not a beginner¹s project! But if you do manage to
get it going then you will certainly learn a great deal. A scope is an
absolute must!

Cheers,
Andy

2010-05-14 by Jed Jorgensen

Hi Vincent,

Yes, put R9 back and re-jumper the trace you cut. That modification isn't
recommended unless you have LFO noise present that can't be fixed by another
method. I've updated my website to make that clear.

The calibration procedure on the VR's is necessary to make the board and the
P6 function correctly. You can begin parts of the procedure without an
oscilloscope, but as Andy noted you have to have one to do the job
correctly.

Do you have a copy of the service manual? I'll put one on my website soon,
but I'm pretty sure it is in the files section at the yahoo groups page.

Vincent,

I've put a copy of the service manual on my webpage here:
http://sites.google.com/site/jedjorgensen/klm367a/images/pcb-bugs-errors/manuals<https://sites.google.com/site/jedjorgensen/klm367a/images/pcb-bugs-errors/manuals>

<https://sites.google.com/site/jedjorgensen/klm367a/images/pcb-bugs-errors/manuals>This
is not a complete copy of the manual, but it has the calibration procedure
that you need to follow. The calibration procedure for the 367 board is on
pages 10 and 11.

Man, I'm way too impatient this morning. Andy just sent me a complete copy
of the manual. That is now up on my website. I'm also putting a copy in the

Re: MG section problem

2010-05-15 by kluberrrrr

HI there!

I'm really you guys crossed my thread!
Thanks again to take time to help me!

To Jed and Andy, I will undo the R09 fix tomorrow,  I'd like to start as
well the Adjustment Procedure where there is some parts I don't
understand at the very beginning of the procedure I should verify the
power supply with the test point on the "J" ??? What are the J 's, are
they some diodes? or resistances? And then ON the Reset Procedure there
is something with a 52Ko resistance but I can't get to understand where
i should put the legs on ?
and for the MG "Calibration" I really need to use an Oscilloscope but I
found there was some software equivalent.  What do you think about them?
I'll still look on ebay...

I still did some tests with the buttons and knobs.
Here the result:

OUTPUT SECTION

Volume : Ok
Output SW : Ok

TUNE SECTION

Tune Knb : not sure

VCO SECTION

Octave : Ok
Waveform selection : Ok
PW\PWM : hard to say
PWM Speed : hard to say too
Sub Osc SW : Ok

VCF SECTION

Cutoff : No
Resonance : No
EG Intensity : No
Keyboard Track : No

VCA SECTION

VCA Mode : Ok
Attenuation : Ok

ARPEGGIATOR SECTION

Arpeggiator SW on/off  :  Ok
Arpeggiator Speed  :  Ok
Range SW  :  Ok
Mode SW  :  Ok
Latch SW  :  Ok

MG SECTION

Freq Diode : Yes but not sync with the Freq Knb
Freq : No
Delay : No
Level : No
MG Mode : Ok

EG SECTION

Attack : No
Decay : No
Sustain : No
Release : No

EFFECTS SECTION

(Once again it's hard to say 'cause I hear the notes played only on the
"top" of the modulation so it's hard to define phaser ensemble or
chorus)

FX Mode : Seems Ok
Speed\Intensity : Hard to say

BEND SECTION

Bend Intensity : Ok

WHEELS

Bend Wheel : Ok
MG Wheel : Ok

KEY ASSIGN MODE SECTION

Hold : Ok
Chord Memory : Ok
Unison : Ok
Poly : Ok

PROGRAMMER SECTION

All the numbers work when pressed but can't hear the difference


By the way thanks a lot for the Manual Service I found one on a website
but yours is best!


Looking forward for your answers


Cheers!



Vincent

RE: [PolySix] Re: MG section problem

2010-05-15 by Paul T

there is a blank white plastic 2 pinned connector just below a capacitor and near a VR on the rear panel mounted power board (for the 52k load) - the j1/2/7 etc are the component style 'jumpers' on this board - you put your multimeter probe against the legs of them and get the reading from there - they are marked on the board as J1/2/7 etc. I did mine just the other day as it happens.

Re: [PolySix] Re: MG section problem

2010-05-15 by Jed Jorgensen

Hi Vincent,

What Paul said is correct. You can also use the "Test Points" (known as
"TP'x'") which are little brass hooks with a yellow bead at the bottom. The
first part of the adjustment procedure is on the KLM-376 PCB, the power
supply at the back of the unit. With this procedure you are checking to make
sure the voltages coming off the power supply are correct. Take care in
doing this. If you are unsure about what you are doing, keep one hand in
your back pocket. It is a little harder to electrocute yourself that way.

To make the dummy plug for the reset procedure (56k resistor thing) see if
you can find an old computer mother board and take off a small connector.
The audio connectors should fit perfectly. You'll solder a 56k resistor
across the wires.

As far as the oscilloscope goes, ask around where you live. I've borrowed
one from my co-worker's boyfriend for about 9 months. No need to buy
something that you aren't going to use a lot. I'm sure you can find one
where you live.

Above all...GO SLOW AND BE CAREFUL!!!! Make sure you understand what it is
that you are trying to do...BEFORE you do it. Remember, you are working in a
circuit that has electricity applied to it. This is dangerous if you don't
know how to be careful.

Also know this: this is an extremely challenging project if you have not
worked on electronic circuits before. It is a good idea to find someone
where you live who can help you!

Jed

Re: [PolySix] Re: MG section problem

2010-05-15 by Andrew Jury

Vincent,

Many of the functions which are not working are reliant on the multiplexor
bus (the two 4051s). Given this you should definitely attempt the, first ,
the reset procedure (the one with the 56K dummy load) and then, second, the
D/A convertor before you do anything else. Make sure the controller are set
as per the diagram at the start of the calibration section of the manual.
You may find some marked improvements when this is completed!

Cheers,
Andy

Re: MG section problem

2010-05-15 by kluberrrrr

Hey,

Thanks everybody for your explanations

So I did check the battery Voltage ( in the service manual they said it should be between 3.6V and 4.10) my multimeter gives me 3.0V but since the battery is no more the same it's correct.
I checked the  power supply, every VR have been verified.
I put a 56K on the 2pin connector of the KLM-376  board (should I use an 1/4W or 1W  resistance?) then I turned the VR1 on the KLM-367...but nothing happened.
Bank A, Program 1 and Tape Enable are lighting on with or without the 56K connector. whatever how i turn to the clockwise or the counterclockwise theLEDs remain the same.

When I turn the power on ( without the 2pin 56K) I noticed the Tape LED is always lit. if I switch to enable the LED turns brighter...

Should I continue the procedure with D/A adjustment?


PS : I noticed something weird when I press a key six time in a row the D10 on the unit 4 and the unit 5 don't light. Does it mean 2 voices are kind of broken? 

 Cheers!


Vincent

Re: MG section problem

2010-05-15 by kluberrrrr

Eventually I did the D/A adjustment. All steps went fine except the 7 one because I don't have an oscilloscope yet. (working on it)

Re: [PolySix] Re: MG section problem

2010-05-16 by Andrew Jury

Vincent,

So let¹s recap... 

You checked the voltage rails generated by the power supply were accurate.
You checked the battery as well (not necessary at this point but OK). You
added the shunt resistor on the power supply with the P6 off (a 1/4w 56K
resistor is fine) and switched back on. Before you did any measurements you
waited at least 30 minutes before checking. Good!

When you tried to adjust the reset circuit you couldn¹t get anything but the
A1 patch LEDs to lights. No matter how far you advanced VR1? OK Here¹s what
is going on. When you set VR1 you are setting the threshold on a comparator
circuit. At a given voltage, when the P6 is powered up, the output of IC5
will momentarily dip to 0v for a prescribed time which you set using VR1.
This pulls pin 4 of the CPU (amongst other things) set the logic on the
board to a known state. (This is a very basic explanation of what is going
on ­ if you are reading this and are an engineer sorry!!). If you cannot set
the reset circuit up then might I suggest you check the following: check the
polarity of D2, D3, D4 and C21. Also be aware that D2 is a zener diode and
provides a reference voltage of 3.9v. If you have used a signal diode such
as a 1N4148 instead (have seen this done before) then this voltage will drop
to 0.6v and render the circuit in operative.

Just a few hints there. Work carefully and methodically and don¹t jump from
one thing to another! That's what they taught me at circuit school anyway!
;-)

BTW I tried to send you a mail to your Œfree.fr¹ account. It is full up! I
was offering you my help if you need it. If interested send me a private
message.

Cheers,
Andy

PS. Don¹t worry about the voice section until you have the 367 working. One
thing at a time, as above!
