I'm getting ready to replace the 132-153/154 on my mcintosh 2100 circuit board but need help identifying the old part that is still on board rca 038 and 039. Which corresponds to 40409 and 40410? lizo
Listed in 1973 RCA data book. What would you like to know? They have a heat sink attached. 40410 PNP, -90V. 40409 NPN, 90V. 3W
I'm working on my own 2100, and I'm replacing those transistors with Fairchild KSA2690A/KSA1220A.
