Gents,
The Heathkit SB-1000 amp has a very small (tiny) coil in series with the B-
and also has a 1N5408 in parallel with the B- right after the tiny coil with
the anode side to ground. Component designations are L401 and D401 on the HV
PS board. What are they for?
Note: These are tapped off right at the bottom of the last cap used in the E
doubler.
