Been a LONG time since I last posted, many things have happened like RETIREMENT ! YEAH !!!
So my current system has 2 BA-3k's , each running mono, driving Westlake BBS-M 15's fed by the 3k Pre I did here MANY MANY moons ago.. The other day ( post household mishap in the plumbing dept ) I thought it would be nice to fire up the main system.... the right amp went CLICK and the nuttin.... The main fuse blew.
I had an 8 amp in there and it called for a 10 A...... New fuse in CLICK smoke POOF..... GRRRRRRRRR.
So off to the bench it went. I had been working on a Pioneer Spec 2 ( japan version M-77 100 volt ) . So that was not completed but stable enough to run... and we had tunes again. So with the fuse change I took out the 2 4 ohm inrush resistors, the left driver & 3 of the 6 output transistors. I THOUGHT I had an excess of OE output transistors.. but the gains of the devices are 80 to 125.. where the ones in the good right channel and the 3 that survived in the left are in the high 30's to mid 40's..So right now I have the protection board repaired, both the drivers working and the right main block working. I placed the Digikey order today for more MJ transistors.
Hope all is well with you guys.....
