Hi :


Can somebody help me with what the UF4007 does? Is it really necessary and will a 1N4004 be a good substitute?


Also how critical to performance is the 100uf that is connected to pin 4 through a 10K resistor?


Thanks

I am subscribed to this thread, it is old, but
Do not use a 1N4148, it does not have enough current capacity for the clamping function, a 1N4004 will work.
100uF is not very critical, it is part of the power up mute circuit.
