RE:Here is a photo of the bottom amp

Right, i measured the residual AC on my bias supply and it is around there .002volts. The only thing that is out of the ordinary is the filament transformer which got hot after 45 minutes. It is a used transformer so maybe a question mark as to its reliabillity? This trans is connected to a .8A 6.3v tap. It is not unbelievable that previously it may have be over worked. If it was actually abused could that cause it to not maintain it voltage regulation?
