Teisco 60F - dead VCO?

I guess I'm not lucky with the synths at the moment haha. WCO is not working... the noise slider has effect and reacts on all controls. so i can modify it with lfo, filters and envelope. but vco slider does nothing. synth section is quiet. range and waveform selector has no effect, only green leds a...

i have no oscilloscope so it's pretty hard to say about reset/generator. any chance to measure it with a meter? sockets are ok. eprom sits nicely, sockets also.

Korg PE 2000 - issues with pipe organ 1/2

Those sounds consist of 2 sounds stacked together [lower+higher octave]. C is missing lower tone, C#-D higher, D# lower, E-A/B are ok, A# - lower. other presets are ok. where can i start my debug?

Re: Roland JX8P no sound

synth does proper countdown. i can access all parameters, edit them, but there is constant buzz on output. if i'm switching to sound with high resonance or sync i can hear the diffrences in that buzz/hum (eg sync with locked phase). when i've connected module to jx8p i was not able to control it via...

Re: Roland JX8P no sound

sadly the sound at TP5 is same as on the output :( I've exchanged IC50 (4052), 58/64 (4558) but this changed nothing. Went step further and changed IC70 (M5218) but still nothing. IC51/52 are fine. What can be checked now?
