Hi guys. I recently bought an old Ampeg 6L6 bass amp and the Sovtek 6L6s it came with are testing positive for grid leakage. So they need replacing and I'm not too familiar with this tube type. I've never owned a 6L6 amp myself. I'd like to keep them really cheap, $30-40 for a matched pair. I'm leaning toward the Russian 6n3ce tube as I've heard great things about them for cheap. Any other recommendation? I can't get the coke-bottle 6L6 as it won't fit into the case.
Thanks!
