I'm trying to help a friend replace the cement resistors in his Gemini GSM-3200 but I'm having a hard time finding replacements.
The values are:
100 Watt 20 Ohm 5% (100W20Rj)
10 Watt 75 Ohm 5% (10W20RJ)
I think I might have found a replacement for the 10W on parts express, but wont know for sure until I can get the lead spacing measurements from the crossover. The other one I'm having an even harder time. I did find one cement resistor, but it has the wrong type of leads (sort of like a double lead sticking out the bottom on each end rather than regular axial leads, I think it might be called "chassis mount"?) and another aluminum chassis mount resistor.
I'm just wondering if the aluminum would work in it's place, or if I need to stick with the ceramic "cement" type? Both would need a bit of modification to work. The aluminum ones appear to have a hole in the "leads" on each end to solder a wire into, and on the cement one with different leads, I'd have to try to modify those by bending the leads out and cutting to get it to go into the hole if possible.
Anyone have any advice on this? The speakers are 300W speakers if that matters.
