My '62 Fender Tremolux was accidentally dropped a while back and since then it still works but after a half hour or so of use the chassis is EXTREMELY hot. So hot in fact, touching the metal sleeve of the speaker cable on the back would easily burn me.
The closest schematic I can find for this amp shows +365v on pin 8 of the GZ34 rectifier ... but when I check DC voltage I get 430v on pin 8. And both the power tubes and rectifier tube are scortching hot. Is this normal? I get the feeling something is wrong but I don't really know what to look for or what to check.
Any help would be greatly apprecitated. Again, the amp works fine, it just gets really really hot ... to the point that something seems wrong.
Here are voltages:
5.45v AC yellow wires from PT to rectifier across pin 2 and pin 8
429v DC at the CT of the OT (red wire)
Plate Voltage on preamps:
V1 pin 1 - 187v
pin 6 - 205v
V2 pin 1 - 187v
pin 6 - 207v
V3 pin 1 - 235v
pin 6 - 236v
V4 pin 1 - 203v
pin 6 - 185v
Bias Voltage 6L6GC power tubes:
V6 pin 5 - -37.2v
V7 pin 5 - -37.3v
Plate Voltage on power tubes:
V6 pin 3 - 425v
V7 pin 3 - 425v
