[Wswss] for sale

[Bob]

I have new a WD7S triode control board. http://home.earthlink.net/~wd7s/triode_control.htm 

I got one from him to use to control the a HF amp.  It was a kit and have it all put together.  It will completely

control and protection for a homebrew or commercial grounded grid amp.

I did not build the amp and like to sale it.

I paid $135 for it and had to buy a center reading meter. The meter tells when the amp is tuned for best power out.

I would like to get $170.00 all.
