Can anyone tell me what Q7 is in this amp. This is the version that has 2 torrids on the power supply
MMBT5551, likely. They would be marked G1. The transistor next to it is the same transistor. This is from an amp with 4 transformers but this should be the same. It's the DC offset protection.
Thanks sir. I also have another question. I am attempting to repair this amp from a previous repair. It came in with two shorted output devices. I dont own an o-scope or have access to one. I have removed all the output devices. When I ohm out all the pads, gate to drain, gate to source, drain to source. Everything checks out no short. But when I used diode setting I get readings. My question is, is it normal to get readings on diode mode, or is there an underlying problem? Thanks in advance
You could be reading other transistors or diodes in the circuit.
If this is for a different amplifier, start a new thread (including make and model in the subject line) if you have more questions about it. Having multiple repairs in a single thread makes the thread, essentially, useless.
