My old beloved 100w Einstein started melting power tubes for no apparent reason. Tried to swap for some new ones, same behavior.
Does anyone know any repair center in Portugal? I tried to check on Diezel site, but I think it's down.

Thanks.
 
Go to any local tech near you. Is it JJ KT77 giving you problems? If so maybe you have to tighten up tube sockets and clamps, I had same issue with JJ, Peter Stapfer told me it has something to do with tube socket size, I was told that JJ connectors are tiny bit smaller size than typical Russian or China power tubes, therefore clamps on older amps(that was shipped with EL34 from China or Russia) was a bit bigger and JJ might be a little loose there.

Thanks for the help. Actually I tested both EL34 and 6l6, all from TAD, I've been using this brand since 2014, with no issues util now.
