Hello again!
If you can not find the semiconductors you need to repair the amp in Mexico then the closest US supplyer to you would be Mouser electronics in Texas.
They stock NTE semiconductors.
The output transistors are NTE 130 like I posted before, but if you need more than two of them I would order NTE130MP which is a matched pair.
If you need 3 output transistors, order two matched pairs.
The orignal driver transistors in the heatsinked boxes(38737 and 38736) cross over to NTE129 and NTE128 respectivly.
These do not have the box heat sink anymore so you will need a slip on top hat type heat sink for each transistor.
Another good repplacement for the oringinal RCA output transistors would be Motorola MJ15050.
The amps 3 amp fuse is likly blown also and you will need to order one of those.

If you have never worked on electronics before I would get the amp repaired by a electronic repair tech and have him contack us if he has any questions.
