Hi everyone,I just found this board and couldn't figure out how to search it, so forgive me if this has been covered in the past.
One of my Svetlana 300Bs has gone bad--only half the filament is lighting up. I've now read about reliability issues with these tubes, so I want to find something else, since they clearly need to be replaced.
Any recommendations for a tube that has worked well in this amp? (mine are built without any modification to the schematic and with Audio Note OPTs). I've seen Electro-Harmonix Gold Grid, JJ Tesla, and some others. WEs are not in price range.
And a related question: I've got 425V on the B+, so I'm not sure if can use mesh grid tubes. I understand they need about a 20% reduction in B+ (they were not around when I built this and I haven't really kept up with things since then).
Thanks a lot,
Jamie
