Great idea putting the fuse in there Bridkarl! I would still have that console that Dad (really Mom and my sisters) made me toss after the transformer fire caused by a shorted 5Y3. I always install a fuse in a transformer powered radio (The 35Z5 / 35W4 is its own fuse in an AA5). I also disconnect the HV Secondary to the 80 / 5Y3 plates and put 1N4007s in series between the winding and the rectifier plates (Observe polarity). I can't remember where I got that from, maybe Phils Old Radios or Ron Ramirez. Protects the transformer in case of a plate to cathode short in the 80 or 5Y3. Not really necessary on tubes with sleeved cathodes like 5AR4, 5Z4, 84, 6X5, etc.
