So what do you all think about using an RF Parts RFC-3 (225 uh 1.5A 4KV) plate
choke as the safety choke for a large HF amp?
The supply is 4KV at up to 2A, bridge rectifier with 32uf of filter. Although
the supply *can* source 2A CCS, the duty processor will drop the mains relays
if more than 1A flows for more than roughly 100us. Whether that happens as
designed or the mains fuses blow first I don't know yet.
Anyway - the circulating current in the choke should be low enough to ignore on
160m, and the effect on the tank should be manageable, especially since this
amp won't run above 20m. (in this incarnation at least) I *think* the wire
should be large enough to hold until the mains fall out and the caps discharge,
but I'll have to think up a way to test that without stressing the supply or
myself too much.
I got the idea from an old posting of Ian's, in case anyone experiences deja
vu... ;-)
Thanks and 73,
Jim, N7CXI
