First of all, I think you should look for something common in your devices. AND check power supply, grounding etc. It's rather strange you have such a big number of burning all the time! And where is your fuses? Why did they not blow? Do you really have grounding (the third) wire in you power outlet?
So i figure it's the .01 cap's in the powersupply that went.I have them on order.
To check - you do not have to buy another cap. You can easily remove it from the PCB and use the device without it. It may affect sound, but the device should work.
Another guy told me that he had the same problem that the cymbal's were very hot.He had to build a fan to blow on it.
Could it be a bias problem?
It could be a lot of sources for the problem, but since you have similar problem with almost all your devices, I think something is wrong with the usage or power outlet or something external to the devices.
One other question i never got answered.Do you have to fill the whole top of resisitor's?
Have you tried to read the manual?
"Not every spot on the circuit board is populated. Many parts are marked either “L” or “R” to indicate channel. Only those parts needed per channel are used, refer to schematic."
I checked the bias... 0.010. Is this right?
BIAS of what stage have you measured? If the last (power) stage - it is written on the scheme (1.2V to ground).
First stage BIAS also mentioned (4.5V cathode-ground)).
