For this discussion, please refer to pages 39-43 of the below-linked
1. Is this a good practice for "...trouble shooting the the first stage differential amplifier..." that can be used with most, direct coupled push pull integrated power amplifiers? Right now I am thinking of it as pertains to a Pioneer SX-939 with a suspect, "long tailed pair."
2. Is it necessary to disconnect the output transistors?
3. What happens if you don't?
Thanks!
