Amp/Preamp Asylum Looking for a new Amp or Preamp? If you're after tubes, post over here. |

Was wrestling with my 3rd generation (Blue/Red) B&K St-140, using spade lug connectors (large ones) and managed to let the + and - on the R channel touch.
Fired it up, right channel MIA. Checked the connectors. Crap! Checked the speaker fuse. Blown. Replaced speaker fuse with correct value (5 amp, 250 V fast blo) and fired the 140 up again.
Right channel back but very distorted. Guess the fuse didn't blow fast enough to overcome my stupidity. Have no idea what was damaged. hoping to find a repair tech in the northern Virginia area who knows B&K amps.
Just hope it's not one of the 4 MOSFETS on that channel because those puppies aren't easy to find.
I repeat. Grrrrrr.
Opus 33 1/3
