Replace with your known working stock tubes, provided they were working. Always have on hand a working set of tubes to check against. My guess, one or more bad new tubes if the old ones worked. Jallen
Tube amp stopped working
I have canary CA 160 mono amps. I replaced the tubes and one channel stopped working. I replaced the stock EL34 out put tubes with Gold Lion KT77. The one channel sounds better. The second channel does not play at all. All the tubes including the input tubes light up. I don't see a fuse on these. Have I missed something? Thanks
