There are no chokes in Alpha power supplies.

>Power transformer might be to small for 4 kw input.
The power transformer is good for 5900 watts input. (The ones with the 20 amp
filament winding)

>Plate meter out of range.

There are resistors that come with the two-tube kit to make the meter read
2 amps f.s.


>Grid current trip circuit not working properly.

Alpha 77 series amps do not have any grid-trip circuitry...you must be very
careful.
A 100 watt exciter can damage a pair of 8877 under certain operating
conditions.
