I Have t1 that is mostly all there. I had to fix the power supply one of the 15 volt regulator was out. The P487B card had small caps shorted. I reversed engineered the schematic diagram and showed board layout componet names. Also names and colors of the in and out put wires. I’m in the process of replacing the small caps.

Have T1 that is 80 percent restored but the b and b flat with the draw bars 16 ,8,4,2 has no sound. the other draws give sound on these notes. also the percussion delay has a ringing sound fully out.if the percussion is selected on the settings other then 16,8,4,2 then it sounds OK. any ideas. Thanks!

Someone gave me a salvaged Cumar keyboard said to be from a T2. Not in the best shape – it’s difficult to keep (or to believe that) the PCB attached to the assembly, and I am yet to think of a simple solution to keep the PCB stable where it is without means that may make future repairs difficult to impossible. Any tips?

Also, three of the springs that are soldered into the PCB and go through the slots into the keys in order to touch the ‘bus’ are kinked/twisted/etc. Anyone have a source or some to spare?

All the springs are gold on the soldered end but corodded black on the keypad end. Some De-oxit helped it get a little more grey than black, but it’d be nice to know how to really get it all back to clean contact – without destroying any additional springs in the process!

Hi,

I have a duo vox accordion with a crumar tone gen. (apprx-20yrs old).
The model is before the magic-vox came out.
PROBLEM:
treble Eb and F do not play (electronically).
Would you have a schematic (or know where I can get one) so that I can isolate problem to a particular pcb?

Thanks, in advance.
Victor

Hi Bruce. I’ve got a pdf service manual for your T1…….found somewhere in the net. CA3080, uA741 and CD4016 are possible causes of ” no sound “. Well, I can send you the manual but need to know where.

Keith: do you know if anyone has a PDF service manual for a T1 ?: my friend Tony (message below) and I are trying to repair one.

[The first night I was checking it out, I noticed it was quite severely out of tune and when I tried to turn the tuning pot on the back panel I found it was totally frozen. When I tried to turn the pot with vise grips, it broke and the keyboard stopped outputing musical sounds and only provided strange noises. I replaced the pot with another of the same value and it seemed to do the trick; it was working again (not at 100% but like it was working before). The very next night when I turned it on, something must have happened because now there is no sound output except dull clicking noises when keys are pressed. Also, the rate LED for the Vibrato/Tremolo section (which had previously been working fine), is now no longer blinking at the rate of the LFO like it should, it is now solidly on. So it seems like one or more chips which must have been on the brink have finally blown. I've noticed that most of the chips are in sockets which would make them fairly easy to replace, but at this point I have no idea where to start.]

Thanks in advance,

Bruce

Hi Keith!

Thanks for your answer. As I have allready said I’ve got an older model of Organizer. At that time (1975) it was called “Organizer 1″. It is predecessor of T1, based on transistors with 12 separate printed circuits, one for one tone (without dividers!). It has no LEDs. Look at
