maybe im crazy, but i swear i remember just a few months ago that mouser only had 22m R's that were like a buck a piece or something. i just ordered last week and got 22m at their normal resistor rate-100 for $.02 a piece. just my 2 cents. da dum crash. --- In cgs_synth@yahoogrou

mark, sorry i can't explain it. i don't have much knowledge of tubes. but i built it thrice and spent many hours testing and measuring. i basically used trial an error to choose my resistor values for the circuit. i have no idea how the voltage at the input grid went down below t

Good idea. How are you doing range. Are you switching in different caps? I need to wedge it into one space (1") so I only get 8 pot/jack positions. My idea was for the top LFO to do Variable out, Vari pot, Shape pot, Frequency pot. Then for the bottom LFO: Pulse out, Saw/Tri out,

Whatever you decide, leave place for the range switches. I stated with an on-off-on toggle switch, but now I have a 6 position switch. I haven't measured the frequencies yet, but it goes from audio to very very slow. Didn't like it in the beginning, using it all the time now. Che

I see Ken has utility LFO boards again. I'm thinking of putting one together. I'm a little confused as to what the waveshapes it puts out actually are. Will the variable out go to full square? Seems like it should. What is the difference between the square and the pulse wave? Jus

Just to be perfectly clear here, I was referring to Digikey not Bridechamber. That they are both in Minnesota is merely coincidental.

So according to Ken's pages, useful values tend to range between .047uF and .47uF? I want to use polystyrene caps for these, but the biggest values I have are 10,000pF, which it seems would be really short time. What values have people found good to use here? I don't even know wh

I have gotten 20, 22.1 and just ordered some 22M 1% metal film resistors from Mouser. I had to search a bit but they had Koa Speer units, Vishay and IRC in 1/8, 1/4, 1/2 watt and in 0.1%, 1% 1nd 5% The reason I am teling you all this detail is the price. The difference between a

While I haven't finished my coffee, it looks like Mouser stocks 1% 1/4W metal film (which do seem physically large) for about a $1 each, but there are even more choices for 22.1M metal film resistors, like this one: 660-MF1/4DL2215F for .42. If you only need 5%, you can get Xicon

>How crucial is it that they are 1% metal film? This is what have most of the resistors as so far. The primary issue is noise. Carbon resistors are noiser than metal film. Also the higher the resistance, the greater the noise generated. That said, with a value like 22M, you usall

Imho, the first step would be to figure out what sort of signal you have. Is it a positive voltage, negative voltage, or a collector?? What is producing it or what is it driving?? From that you can get an idea how much current it can sink or source. Then that will tell you what s

It does sound like you have an issue around one op-amp. Try soldering a 47pf capacitor between pins 1 and 2, and another between pins 6 and 7 of the op-amp that is giving trouble. You may have a stray capacitance issue with all those long wires. If that solves it, do the same to
