Well I picked up a 2105 yesterday at an estate auction in an untested state along with a MR74 and a C26, a Teac 3300S and some University speakers all for $600.00.
There was no way to test the units since they were brought out from a basement and sold from a big flat hay wagon in the middle of a field. But I thought for the right price I would take a shot, even though the 2105 did not have a fuse in it.
Sure enough, today I hook up the amp, along with the other units, and it blows a fuse as soon as the power is switched on. So I do a little research on the old infoweb and it sounds one possibility is a short somewhere in the driver section or bad driver boards. I remove the covers and pull the drivers as suggested and power the unit up again. Fuse blows instantly again. Well, I am thinking major problems here. Then I get to looking around and I notice that the right channel driver board has had a resistor replaced (see pictures pretty severe burns to board). This leads me to believe that the problem is in the right side. I get to looking around and I see a green wire that is smashed up against the chassis sub structure (see photo's), and it has exposed wiring.
OK, this is were the story ends for now. I am out of fuses and need to run to the hardware to pick some up. In the mean time what do you guys think about this? Do you think by powering the unit on and blowing fuses that it could have caused other damage to the unit?
I will get back with an update after returning from the fuse run. In the mean time chime in with your thoughts.
