[AMPS] Grid block keying of SB200 for QSK???

[Bob Duckworth]

Thanks for suggesitons.
and
Thanks BAMA!
It sure helps to have a schematic.

SB200 has grids at RF ground and 
cuts tubes off with a neg bias to grids.

I'm going to nip the wire, lock the relays down
and try keying via the neg 90V keyed line
from the HW-16. 

If this doesn't work, will look at either MOSFET or
using the neg bias from the amp for keying the 
HW-16 rather than the other way around.

Will post pix and results to www early next week.
