Hi All
does anyone have a service manual or schematic for a Yamaha VX35 guitar amp.
Thanks

I only found two sources.

Both want money.

Try asking Yamaha. They usually charge but for older stuff I've found them to be very accommodating (i.e. free).

Agree^^^

I just checked my dealer support page at Yamaha, and there is no manual for the VX35 there. There is one service bulletin that says TR1, 2SC2320 can be noisy, and to replace it with a low noise 2SC2320.

So I suspect Yamaha has it but not scanned.

Is it anything like the VX55?

I googled the model to see a photo and whatever else came up.

Here is the JX35B. Idle current setting is 5mV across the .47 ohm resistor.
