Arcing rectifiers

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Hi, I bought some JJ 5AR4's a couple of months ago and only just now put them in my amps that I use on a regular basis with 5R4WGB's. When I fired the amps up (an apt expression) I got major arcing along the full length of the plates in both tubes. The amps are a DC design with a choke input filter and have been working without problem for a couple of years. When I tried some 5V4's and replaced the original 5R4WGB's I have no problem, just the slightly different voltage drop across each tube you would expect. Anyone have a similar pyrotechnic display with JJ's?
