This is my first journey into tubes. Purchased off Audiogon from a highly rated seller. But when I hooked it up this morning it blew the 5 amp fuse after
about 20 seconds. It started a faint popping in the speakers that gradually
became louder then one last pop blowing the fuse. I checked all my wiring
and all good. Then I notice that in my haste I had tubes V4 and V1 [EL34's] reversed according to their labeling so I fixed that. I then replaced the fuse and it blew again. Watching the tubes as it warms up, the popping seems to coincide with a flashing or arcing in tube V4 at the last moment before
blowing again. The amp came with a spare set of tubes so I have them to try out when I get more fuses.
The speakers are 1.2TL's and were hooked up both times the fuse blew.
Most of the popping seemed to come from the right speaker.
Since this is my first tube amp, any recommendations would sure help.
