[Heathkit] sure will appreciate help on getting straightened out on SB-221

[rbig at cox.net]

The guy that sold it to me said I needed a buffer relay.   What he says may be protection for my tranceiver.   This guy has an article on what I think I may need:

There should be some finished products available for this.  Does anyone know of any?   I'd really rather buy a finished product that to try and build one.   

Harbach has a Soft-key mod they sell (SK-220).   I'm not sure if this is like the buffer relay above, or not.    I'll get it and put it in.

They also have a Soft-Start mod, which I'll get and put in.

I think this one is not like the buffer relay.  I think this is the relay in cabinet.   It's called a Harbach Relay Replacment (RY-220.

Sure will appreciate getting straightened out on all these things.    

Also, does the SB-221 have compatability between ALC from TS-430S, FT-101zd, FT-101ee?   Will those be able to have ALC on this amp?
