Hello guys.
I have a Peavey Bandit for repair. Both power transistors have shorted. I had this peavey just a few weeks ago, with both drivers for these power transistors shorted, and an open SZ-13866 dual diode thats monted thru the heatsink. I replaced the driver transistors with the correct replacement parts according to Peavey, but I couldn't find a corresponding diode, so I used a 1N4007 and it worked. Now with this Bandit back on my desk, I suspect this 1N4007 does not behave so well once the heatsink gets hot.
Any idea what would a better diode?
Thanks in advance

Red LED. Unfortunately the package of a red LED does not fit the slot in the heatsink like the dual diode in DO41 package. A little work with a quill grinder and heat transfer glue may modify the heat sink. Use safety glasses when using power tools.
Wow! How did you find that out?
Well, since a 5mm LED and a 3mm LED have the same volt drop, there would be no problem in using a 3mm. That's what I have on hand right now. I ran out of red 5mm LEDs... Also less drilling involved.
