Re: SH101 Strange Noise bleed

After a pit stop at a friendly tech, I got it back running like a charm :) Learned a lot while looking for the error, and finally discovered the Resonance slider was dead. Followed the signal path all the way from the BA662 to the VCO, and after a bit, found the error. A quick replacement later, and...

Re: SH101 Strange Noise bleed

@Mooger5: I tried the wiggling, but that has no influence on the noise. I've been suggested on Reddit it's either the VCA IC - the BA662 - that's dying, or sliders dirty / going bad. As per this thread: https://www.reddit.com/r/synthesizers/comments/5zwgwb/sh101_noise_bleed_bad_vca/ I'm going to the...

Re: SH101 Strange Noise bleed

The JX had a faulty power supply, and one capacitor that was dead on the MIDI board, which prevented any MIDI of going out.... I indeed suppose they weren't interested. I feel you when you talk about replacements and al. I'd rather not go that way if I can. I could easily fly with the synth and get ...

Re: SH101 Strange Noise bleed

So after much wiggling, I can't say any particular part impacts on the noise. It is affected by the filter to some extent, but still comes through above the filtered signal (with all the OSC volumes down). Moving the boards a bit seem to have diminished it, but as the volume is random, it's hard to ...

Re: SH101 Strange Noise bleed

thanks for the insight. I'm expecting to pay a price for repairs, heck, I've been an architectural consultant in parametric design. I know how much an hour of work should cost. But the pricing I had was 120€ before knowing anything and then 120€ per hour of work. So a whole day here is more like 800...

Re: SH101 Strange Noise bleed

I'll check about the loose contacts and solder joints as you suggest. I'll post my findings ASAP.

The synths behaviour isn't worsening with time powered. However before i truly noticed this behaviour it was something that would worsen over time, until it was there from boot.

Re: SH101 Strange Noise bleed

Hi @Solderman, Thanks for your response. I'm indeed not so experienced with repairs, but my neighbourg happens to be pretty good with electronics, so i'm hoping to ask him for help regarding soldering material etc. Would you recommend doing this mod to fix my issue then? https://tubbutec.de/blog/sh-...

SH101 Strange Noise bleed

My beloved pristine blue SH-101 is starting to show one strange sign of fatigue. After much googling, I simply cannot figure out what is wrong with it. The current issue that I have is that whenever the GATE is opened, some strange digitalish and random noise comes out. This is totally independent o...
