transistorrr?????????
An externally hosted image should be here but it was not working when we last tested it.
They were likely BUZ11s but Rockford was also using IRFZ40s at that time.
An IRFZ44N or an IRFZ48 would serve as a replacement.
Also check the gate drive resistors, the driver transistors for the power supply FETs and the large Zener diodes near the FETs.
If you email Rockford tomorrow, you can get a schematic. It will have the original part numbers.

removing transistors from rf thermal strip
You can remove the transistors easy. You need to obtain a large soldering iron. The high wattage type that is used to burn wood for hobbiest. Let the iron heat up to max. spool off some solder and hold it against the to-220 transistor. Put the HOT iron against the transistors metal tab. Start feeding the solder until it forms a pool on the metal tab. If the iron is hot enough you will feel a pop! The transistor will remove itself from the thermal strip. If it does not disconnect itself fast you need a larger iron. This is how Rockford repairs its amps. To remount the transistor hold the transistor down and apply solder to the top of the tab. Perfect.

Pleaseeeee rockfors transistor ??? punch 60ix
I need to know what kind of transsistor are those that I'm showing you (?). thank you for your help! I'm argentinian.
Have you got the circuit schematic ?????????
