IS that a 2SD1915 or something else, it looks like an 2SA1022 or NTE2407crosses - Newark Electronics or Mouser might be able to provide you a different cross reference. There are data sheets that seem to indicate a A1022 / NTE 2407 - this one can be found here http://www.mouser.com/Search/Refine.aspx?Keyword=2SA1022 Amplifier Transistor - these are common I think for older amplifiers. If memory serves me right - I probably have a couple old ones I bought to fix a Reel to Reel .

Is the right output transistor part number the same as the left output transistor.


Should be provided you only have a single transistor in the output power stage. If you have a pair of transistors in push pull arrangement, then those two units for that one individual channel will be different.

I rather suspect IC1 TDA7293 is the cause of your problem. If this is the case you will need to check the speaker/s

How can I obtain a plugin 100w module for my Stagepas 300 as both output transistors are short circuit plus several pcb mounted driver transistors/resistors damaged.Thank you David Bunn


You could try buying the part from Yamaha America... the music section in California. Transistors and resistors are easily replaceable so repair of the board would be the path I would take myself... but then I am an electrical engineer.

I have this problem. my bass amp is blowing fuses SWR workingman4004 the problem is that not only burns but also fuses the 4 output transistors (2sc3264) and a resistance R22, and replace them when I was...


I don't have a exact schematic for your amp, but I can give you some hints and suggestions...

USUALLY when the output transistors fuse there is a problem at least one level back and sometimes two levels. Often the driver transistors also get fried and sometimes one stage farther where the bias is regulated for the final amp transistors. A schematic is imperative to diagnose and repair unless one replaces every part.

Next, to prevent damage when restarting the amp, put a 100 Watt incandescent lamp in series with the hot power into the unit. This acts as a current limiter and auto-resetting fuse. The lamp will come on and limit the current while one troubleshoots the amp to find what is causing the current drain.

This schematic MIGHT be pretty close to your unit:

I would expect to see Q4 through Q12 destroyed and maybe a few more components. If transistor Q4 opens, goodbye all the transistors! The 1N4004 diodes are PROBABLY big enough to take it, but all the small transistors probably are damaged or degraded... The high value resistors will survive, but the low ohm ones that can draw enough current may be damaged.

Try to analyze what each part of the circuit is for... I think Q13 and Q14 are part of a soft start circuit. This amp is NOT well protected in case of component failure and MANY that fail in the final stages cause catastrophic destruction.

Use my suggestion for the lamp. Often using a Variac to slowly bring up the voltage is handy, but one doesn't only have one available.

It seems there's another component (a capacitor, a diode, etc) causing a short circuit to triac and transistor, or there's an over voltage on this stage, please check if the voltage is according to the one feeding the good channel.

I am attempting to repair a Kustom K100A-1 guitar amp. I found one shorted output transistor, an RCA 36892, which crosses with a NTE 130. Do I need to replace all 5 outputs with matched transistors, or can...


I don't have a schematic for this unit, however good design would not demand matched transistors.
If a transistor has shorted, USUALLY mating transistors have been damaged. I am not sure how "5" outputs are configured as usually there is symetry and an even number. If the "5" are all on one side and there are mating trnsistors of another number, then likely there is damage to more components and probably back one stage in the drivers or even farther.
Hint: when re-powering this after repair, put a 100 Watt light bulb in series with the power into the unit to act as a limiting fuse that resets without driving heavy current into the unit causing more damage due to failed parts that were not eliminated in the first reapir.

I have a Pmp5000 889406987784 Eurowpower PMP5000 1200-Watt 20-Channel Mixer and Speaker Output A has no output. What has happened?


Usual problem is the Channel A amplifier has burned and blown the switching transistors. Usually an internal board arc occurs and unless very skilled at board work of clearing the burned area and replacing the components you are better to replace the HCA2400 amplifier module... about $160
