The 6L6 did seem to add a bit more "oomph" .martin manning wrote:I doubt it. The only real difference between 5881 and any of the various 6L6's is the power handling capability (max plate dissipation). The socket spacing is surely assuming the small straight-sided 6L6GC envelope, which dates back to 1959.andresound wrote:Should I rather use 6L6. Might get a bit more clean headroom.
Good to hear you have the hum solved. What does the ground scheme look like now? Still using the cap can for everything except the last filter?
No Martin, still using can cap for all stages exempt last filter. I had too many ground points. Now I have 2. First stage-output section, PI/reverb and V2 and last section-v1. There is still a "small" bit of 60hz which I will address, when Axial caps arrive.
