I fixed up an ST70 and a PAS 5 many years ago. Just replaced all the resistors and caps. I thought it was bass-heavy in my system, but the midrange and highs were great. For the PAS, I replaced all resistors and caps and bypassed all the tone control stuff. I am a HUGE Decware fan. Had a couple of their small entry level amps, and now have a Torii - 20WPC - EL34 based amp. I love all their stuff. Also have one of their phono preamps for a hi output cartridge, and I built an 8" full range open baffle using their cabinet design. The 'AH HA' moment for me was when I replaced my SS pre-amp with the PAS5? PAS3? I forget - and I could not believe the musicality that came out of my system. That was my conversion to tubes.
