December 1990 QST, QSK for SB220
 

I am interested in installing a vaccum relay QSK circuit in a SB220.
If anyone could copy for me, the article, and provide me with it, in
the December 1990 QST, I would be forever gratefull, and would pay any
cost.

Either e-mail attachments or USPS would work for me.

Win,

What you are asking for are the QST articles authored by Rick Measures.
"Circuit Improvements for the Heath SB-220 Amplifier" (Rick's updated
manuscript (2001) for Nov.-Dec., 1990 QST article).

Rick has these on his web site, he

Thanks, gb. I found Rick's site last night and ordered the parts
direct from him for the mod.

Also, I thank Joe, G3LLE, and Danny, K6MHE, for providing me with
documentation via e-mail.
