Yamaha Electone A-55N - Disassembly, Repair, Synth Synthesizer Chip Salvage

A video of my recently aquired Electone Organ - (Essentially working after years spent in a damp garage).
A look inside at the circuitry, in particular the IG02601 VCA and IG02611 VCF chips in this unit (also used on the Yamaha CS01 Analogue Synth). Also, some sounds of the organ at the end.

    Have you found suitable spots on the circuitboard for extra sliders /pots? First thing I'd do for this would be adding custom pots for resonance and cutoff. And possibly envelope parameters for filters as well... AutoWah would get even more spicey with them. Another one would be outputs for everything possible. Possibility to connect those to dedicated mixer is tempting, separate volume sliders for all the separate drum sounds for example.. then some effect boxes to FX send/return loop! It would add vast amount of new performing possibilities.

    really enjoyed this video,i have found yamaha b-605 its partly working, i noticed its similar to this,a few sections don't work,it seems to be the chorus that does not do anything but also some kind special preset section with harpsichord does nothing also,it was dusty as hell and abandoned,i wiped the dust off and it really sounds great,i might get inside after looking at this to see if i can see any degraded ribbon cables etc.i know little about electronics tho,apart from to test voltages with a volt meter.Btw. on the 605 you can layer multiple rhythms at same time:)

    Just bought something similar. I think it has few buttons more and atm I have no idea what exact model it is. By what i found, its closest to A-55-N. Dunno was 40eur to much for it, but its damn fun to play with, also seems to be in good condition, both inside and out. These things have really nice retro sound.

    This looks identical to the model my grandfather had -- I believe it's in my parents shed at the moment. Some of the buttons/switches are not functioning but I imagine some deoxit might resolve them.

    I have the A55 without the N, that stands for New, the difference is that mine doesn't have Auto arpeggio, rhythm variations, and the "disco" rhythm pattern, which was very sought after in 1980-1982. But mine had the Tremolo/Chorus effect and had an extra guitar preset. I wouldn't have changed it for this model. Tremolo and Chorus was probably the best feature of this model. I wonder if they just hid it in the panel but it was still in the circuit board.

    I was just lucky enough to be gifted this instrument. She's beautiful. My friend has had her for years sitting in his garage but I now have it in my room and have no idea what I'm doing. I've experience with keyboards but nothing like this. Everything seems to be working except when I hit a key, no sound comes from it. Is there a special trick I'm missing or do you know what I might need to look at to get the piano and those functions working? Thank you for your video. I figured you seem like a good person to ask since you seem to know your way around better

    Hello. Thanks for the video I got one like this recently but the upper keyboard sometimes sounds and sometime doesn’t. Do you think is going to be easy to repaired? Also, where I can find some kind of course or book or music sheet to start to learn to play this fantastic instrument? I know music (as I use to play sax) and I would like to start to play this Electone Thanks at all

    Hi! I have the Organ Yamaha A55N and the upper keyword does not emit any sound -it seems that it does not receive electricity-. We opened the organ as per your video (great!) but regrettably, we cannot find the source of this issue. The lower keyboard and the pedals work perfectly. Any suggestions or ideas will be deeply appreciated! Thank you!
