[Amps] Heathkit HA-10 Warrior

[Allen Jones]

I am in the process of refurbing a Heathkit HA-10
Warrior amp.  I have looked at some of the old threads
dealing with this amp and have a couple of questions.

The 866's will go in favor of plug-in solid state
replacements.  Am I going to end up with a lot of
extra B plus?  The power supply is choke input to a 8
Mfd capacitor.  Would a step-start circuit be of any
value or will the choke be enough to limit the surge?

Are the original parasitic chokes sufficient or should
I replace them with something different?

This amp has had two plate transformers fail for the
previous owner.  He used the amp on RTTY. I got a new
transformer from Heyboer and asked them to build it
for CCS.  The vast majority of my operation will be
SSB. I plan to scrap the fixed bias supply and go with
a zener in the center tap of the filament xfmr in
series with a high value resistor which will be
shorted with a relay in transmit.  I will ground the
grids of the 811's directly to the chassis with heavy
braid or copper strap.

Any other suggestions?

Thanks

Allen Jones, W9DZ
