Ampapa A1 - Tube Phono Pre Amp and Headphone Amp

[@Elegiac7]

12:00 o clock on the dial is default level for bass and treble. To the left of 12 is less, and to the right is more. Similar for the volume, for when you're using it as a tube preamp/buffer. Also try some RCA 6ak5's. Anyway, you'll hear the stock tubes more once you have the dials at 12, and you're not lowering the signal below input levels.

Don't forget tubes need to burn-in, given time the sound would probably improve !
