Hi All,
I have a Rotel RA-980BX amp with a blown channel. I have sourced most of the transistors, but am struggling to find the other 4.
Part numbers as follow:
2SC3478
2SC4381
2SA1376
2SA1667
What would be suggested equivalents / suitable replacements?
Also, some advice, I suspect the bias pot to be bad. Based on the circuit, would you think that the bad bias pot would cause the drivers and outputs to blow? Any suggestion on modification to prevent this re-occurring?
Thanks
Regards,
Werner
