Ron,
Larry has a AC-4 so he's good to go on the AC4-R from Mike.

Larry,
Although I prefer the Heathkitshop board, for the AC3, I would go with
the Hayseed Hamfest caps for the following reasons.
First, the AC3 has a test point on that the AC4 does not and the
Heathkitshop board does not account for. That test point is the
absolute easiest way to set the finals bias current on a rig. I
modified my Heathkit shop board to accommodate this test point with my
AC4. Second is that the AC3 does not have a cover. That means that
with the Heathkit shop board, you have exposed voltages on the top of
the chassis.
I personally prefer the Heathkitshop board, but it was designed for the
AC4. It is your call, but if you do use the board on an AC3, please
make some type of cover, or make other accommodations for safety.
Death is permanent.
73,

I have an AC-4 but the documentation that came with the T4-X is for
the AC3.
All the electrolytic caps have to be replaced as well as some other
parts.
Differences between the models?? Also sources for the caps?
Thanks for any help you can give.
