There is more ways to skin a cat. Dick possibly didnt know about the
Ameritron choke or the 3 versions before it came out right.
Id be willing to bet there are a lot more 8874/3CX-800 Alphas on both WARC's
than Dick ever dreamt of doing.

I also have a 76PA that has been upgraded to 3CX800A7'S, vac relays, etc
done by Dick N4UQ.
Its been a while since I have asked Dick about mods to my 76PA for 12M
but as I recall it was a more extensive mod than
just swapping out the plate choke and I decided not to do it. I would
bounce this question off Dick again to get his input.
Let us know what you find out. I would be interested in doing a 12 m
upgrade also if it wasn't too big of a deal.

That choke is the same as the $20 Ameritron and works fine in my stock
tubed 76PA. Placement is a bit tight but Ive had no arcing or detuning.

I have recently obtained an Alpha 76PA that has the 3CX800A7's, Vacuum
Relays, and low power modification and meter modification, apparently
done by Dick Byrd N4UQ some time back.
The 12m mod was never performed and I would like some input on this.
I read an article by Mat KK5DR that this can be done simply by swapping
out the plate choke with an RFC3 from RF Parts.
Is it that simple?
thanks 73 Dwight NS9I
