[Heathkit] Rebuilding Heath HA-10 Warrior power supply

[Rick Poole]

If I had to rebuild an HA-10 power supply (as if, for example, the 
power transformer was blown), and if I didn't care about keeping it 
original (I don't, especially), I would consider something like the following:

1.  Replace the 811A's with 572B's

2.  Install a Peter Dahl / Harbach PT-220 (replacement power 
transformer for the SB-220/221)

3.  Install a voltage doubler with lots of capacitance and get rid of 
the swinging choke, and end up with something up to 2500 VDC at up to 
600 ma CCS

4.  Not sure (yet) what I'd do for a filament or bias supply... would 
need 6.3 VAC at 16 amps and not sure what for bias (up to 100 volts 
at the transformer secondary?).

This should let me drive the amp to 1000 watts PEP output comfortably, on SSB.

Does all this sound reasonable?

Anybody know what the HA-10 power transformer and swinging choke 
weigh?  A hoped-for bonus with this, besides ending up with an amp 
that works better than new, is that it should be somewhat lighter in 
weight.  That is a factor in my plans for mounting.

Thanks...
