Amp/Preamp Asylum Looking for a new Amp or Preamp? If you're after tubes, post over here. |

I have a McIntosh MC2105 on my bench for repair. Output one channel blown, took 3.32 & 5.6 ohm current limiting resistors with it. Someone has been here before, most transistors have different numbers. There was only one transistor with an insulator under it, I'm assuming this is wrong.
The six output transistors are NPN, Are they all the same part#? On Semiconductor MJ15003G.
The predriver boards have both been reworked, but look unburned, transistors buzz-out OK.
