Vintage Synth Repair

Seems I can only find the ones with 14 pin package ones and I think
there are some minor differences that are going to cause me much pain
in diagnosing this one at a glance. -Bob

if you need datas sheets for a 741 just goolge "Data sheet 741 op amp"
Hope this helps.

Sorry Eli, that's the link that is already pointed to on my
sounddoctorin.com global synth page (bookmark it if you don't already
have it.  Anything you are looking for an ANY production synth of the
past should be there.  If it's not..let me know.  I mean anything of
technical significance :-).  I don't want every picture cluttering the
works etc. :-)

Anyway that link to patrick the mad inventor's page is already there.
 To the previous 'helper'...I obviously don't need the diagram of the
741...I was trying for the solina that USES those instead of the 14
pin ones.  THEY ARE DIFFERENT it appears.  I have a Solina here and I
measured some things that according to the diagram should have brought
in certain readings.  They do not so rather than spending a lot of
time tracing I was hoping I could find the actual diagram of that
*version*.  This..obviously is a later version since 8 pin 741's would
have been more predominate at that time.  Thanks, -Bob

I've only ever seen one set of drawings for the Solina. I have orignals but they look like the ones that are easily found on the net in PDF.
 
I have an early mk1 solina with no gate/trigger sockets and no chorus on/off switch. There are many differences to the one that is in the commonly found drawings.
 
I've searched for 20 years on and off for mk 1 drawings...so if you find any.. :o)
 
Thanks, Phil.
