Yup - that's the PPIMV on bedroom volumes, no power tube clipping whatsoever. Before I blamed the PPIMV for the poor qualities in my tone, as I had to crank the amp to get a good sound, but now that I've got NOS preamp tubes and the right speakers, caps and OT, the sound is great even when you can barely hear it! I've come to realise that power tube clipping was just covering the problem and not fixing it.
