I just finishing repairs and upgrades to an SB-1000, including having
replaced that burned-out 160m switch wafer with an AL-80 spare from
Ameritron.
There was no sign of that particular amp ever having used and
anti-corona washer, and its original assembly manual does not show one.
I'd very much like to add one before returning the amp to its owner, but
I'm still not clear exactly where it should go.
Having already read the "thousand words", I'd really appreciate a
picture! If anyone can take a picture, either of an amp or from a
(later?) manual that shows it, I'd be very grateful.
Unfortunately the SB-1K manual is not available at BAMA (it's on their
"wanted" list) or anywhere else that Google could find.
