Yamaha VR6000 amp & footswitch (Yamaha VFC-3)

[Bernardduur]

Hi all!

Trying to fix my 2 VR6000's. Lot of hisses and noises coming from here, so I'm starting with the ELCO's. Shame is that I can't find a suitable schematic. Could anyone provide me with one?

Also, the unit needs a three button footswitch (VFC-3) that is connected to the amp by a simple guitar cord. I'd guess it is done with voltages that switch the features....... then again, I don't know.

Here is the schematic.

Thank you very much!

Now only the footswitch is left...... I can use the values in the schematic for the A/B and chorus switch..... only the reverb is kinda a mystery now
