Rockford Fosgate Punch 30HD power supply.


i need some help finding suitable replacements for these power supply transistors. they are from punch 30hd.



I did some searching and found that 2N6488 and MJE3055 are a good substitute, but i don't have these parts. I was wondering if there are any other parts that i can use..

thanks for your help
It's generally best to use the original parts unless there is a good reason to use something else. This is especially true here because there are likely other problems and if you don't use the original parts, you may not know if the other problems are due to the substitute parts or from something else in the circuit.

i would like to use the original parts, but they are not made more and i cant even find a data sheet on them. I tried looking at e-bay and other places with no luck.
