I bought a late 70's early 80's PR that was BF'd by a previous owner. The PR came with a 12", 16 ohm, JBL K123 speaker which I replaced with a Weber 10F50T, a speaker that I've have used successfully in Princetons in the pass. I gave the speaker a 24 hour variac break-in before installing it. I also went through the amp and while the BF work was pretty sloppy everything was as it should be value-wise. This amp is bright with a capital "B". With my Tele I have to keep the treble down to 3 - 4 or you get into bleeding-ear territory. Speaker choice? Tubes? Something else? Any help, suggestions, etc. would be greatly appreciated. Thanks in advance.
