    I just finished re-capping my ST-70's driver board.  I used 0.22 mF for the 4 coupling caps and I also used the same 0.22mF for the other two that were originally 0.05 mF. First impression is the bass seems to be more pronounced. After a bit of reading, I see that I probably should have used 0.1 mF for the two that were 0.05 mF.  I'll go back in and change those out to 0.1 mF if that's the smart thing to do.

    By the way, I just used the white tubular Cornell Dubliners from Mouser rated at 600V, wondering if anybody else has used these in audio circuits.   Sounds good on first impression.
