[Heathkit] foldback

[Mike Hyder --N4NT--]

Hi Bruce--

When I first tried to tune my SB-220 on 10 meters, I thought I had it tuned
right but had low power output.  I found that the load control had to be
advanced quite far (on the order of position 6) to get the proper loading.
Thereafter I would begin the tune-up procedure with the load control on 5.

This may or may not help.

73, Mike N4NT

I have a great SB220 with the latest Harbauch mods that I installed.

Question:

My exciter (TS140S) folds back to 50 watts out on 10 meters. How do I go
about tuning the amplifier (input circuit I guess) to eliminate the foldback
issue or is this normal?

Thank you,

Bruce
