Repair Yamaha SY-99 Vintage Synthesizer Reparatur Service21. März 2021
Roland SH-101 synthesizer service. This one came in for an overhaul, a complete restoration.
The first thing I spotted was this section of rust. This is never a good sign. I took a wire brush on my drilling machine and some rust remover. Later also some rust converter. I later sprayed everything with some "zink spray".
Other than that it was usual business, like cleaning all slider potentiometer, rotary switches and potentiometer, switches and so on. All of these were desoldered, opened and carefully cleaned.
I cleaned the keyboard. All the keys, contacts and I also refurbished the rubber contacts.
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.
