When I sold my SVT in 1980 I bought a Mark III and immediately modded the crap out of it. I added two more upper bands of EQ to the graphic EQ, added an active aux in with a presence control. I also added a compression control to control the DDT compression and upped the main filter capacitance for added headroom. I biamped using the tube preamp of my 65 Bassman into the aux input, used the 300 watt SS power amp for the low end, and the 50 watt tube power amp in the Bassman for the mids and highs.
Into a pair of 1820's and a bank of Piezos and it was glorious! It served me well for years..
My favorite PV amp.
