Recently bought a Leben CS300XS (100v model using a good quality stepdown tranny from 230v) which has worked great. The amp came with the stock Sovtek EL84/6BQ5 and GE 5751.
Decided to do some tube rolling so bought a pair of Amperex bugle boy ECC83 / 12AX7, a nice improvement in SQ.
Next I bought a quad of Baldwin (sylvania) 6BQ5 black plates and on inserting these this morning the there was a bit of a smell from the amp and the operation lamp went out.
I can hear music but it is very, very faint and crackly. Have put the stock tubes back in just incase but it seems like the damage has been done.
It is looking like this is going to cost a few quid to sort out. Just wondering if anyone else has had experience with this and what it may be?
Any help is appreciated, thanks in advance.
