Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: 300B overbias / underbias questions

To clarify something I stated earlier in this sub-thread: It seems like the mA is distributed between both tubes (obvious, now that I think about it), so you can rest knowing the tubes are probably not being burned up fast.

Now, to your questions:

Trust your own ears. If you like it at 160mA, run it there, enjoy, and rest easy in that you might get a bit more life from the output tubes. I'd call that biasing with slightly less current than recommended by the manufacturer, but well within accepted tolerances.

Ignore the post you linked - in the quick read I gave it, the observations are subjective and the definitions/characterisations (over/under/cold/warm) etc. not typical.

Cheers,
