Hey there Jimmy, I wanted to let you know I found a local guy on FB Marketplace that had a PF-800 in great condition for about half the price of a new one. I hauled my cab to his place, gave it a try out and really liked it. So a few minutes and dollars later I had myself an Ampeg Class-D with carry case and cables.
I just had a gig this Friday and brought along the new edition. I also had installed some fresh strings on my work basses. WOW, what a great sound. And as you said, compared to my previous amp, like night and day. A good friend of mine is repairing the SVT-450H, and that will become my backup. Thanks again for the advice.
