Does the fuse blow or just go out? When it cools off, does it come back on? Also, which chassis(amp) are we talking about? With or without PI tube. | ||

Have you replaced old electrolytic caps? | ||

I'm going to go with bad caps OR a bad connection at one of the heater wires. Get's hot, tubes go out. OR PS transformer taking a whizz. |
