I'm aware it's not the correct way to resolve the issue, skiping the resistors, I'll try to get the spares. In the meantime the bridges are only for testing the unit. The results are not bad at all. I can see two problems with this schema: 1. With DSL disconnected the voice equalization is very different, left channel higher level than right one. 2. DSL engaged I can't hear differents between left and right channel at volume level 5 or less, at higher levels, vocals has different tone Head is in very good shape, I think slightly better than my other unit. The sound is very rich, powerfull and detailled I'll try to get the resistors from a donnor and install them to confirm that it's ok. Otherwise I'm happy to have found the way to fix it. I thought it had not way out for this unit.
I got 48 resistor from a donnor, put in the pcb , right channel with a little suspense, first of all nothing change, resoldering recover the normal level sound, and then again sound turn off... Fortunately after aply new solder layer sound recover definetly. Measuring the old resistor
The resistor is ok! I think the pad was corroided the new solder seems to remove the corrosion. Now the sound seems to be ok, I need a little time to test it well. Now I have to inspect the R17, need a replacement, although it's possible as the R48 actually the resistor it's ok and the pad corroided
Hi, both are black. First had a bad diode and you gave me the idea to solve the issue. Second after recappimg, didn't have sound on left channel, this is what I'm working. Resistor 17 now is working fine, after desoldering and cleaning the pad. This unit is affected by corrosion, I hope in the future there won't be more issues. Now the sound it's ok, actually slightly better than my other unit, head is in better shape. Two issues remaining, a pinch roller with an indent, and a broken hinge
