Repair Yamaha CS30 Vintage Analog Synthesizer Reparatur Service

Yamaha CS30 Vintage Analog Synthesizer. My customer wanted to have an external sync option to sync the internal sequencer of the Yamaha CS-30. He also wanted me to have a detailed look how healthy his synthesizer is.

First thing I noticed was that cosy transport prtotection. You should tell your customer about this or better remove it. The transformer should have some airflow to cool down.

Then, again, I noticed the purple Matsushita caps which always has to go. At least I replace them always! Why? They leak! And they damage your synthesizer with their electrolyte thats coming out of their legs! Some are also way out of spec.

My customer wanted to have Nichicon MUSE as a replacement for the Matsushita caps. He told me afterwards that the synth now sounds incredible

While dissambling the unit to do the re-cap, I noticed the psu pcb was broken and loose. I fixed the corner with epoxy and drilled a new hole in a different spot.

My customer wanted to have sync. So I did a little circuit board to fit inside the synth that accepts any signal from about 3-15V trigger. Its working nice as you can see in my Instagram video.

There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk.

I’m documenting repairs for my reference and yours. I do synth restorations and repair with a specialty in vintage synthesizers, drum computer and other vintage gear, based in Düsseldorf, GER. Get in touch about your synth situation!
