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. Altho

Hi Jim, I suppose you would like to put that choke across the (50Ohm) output terminal ? Think 225uH is not needed at all to have negligible effect at 160mtrs. I would go for a reasonable sized toroid

Hi Carel. I don't think I can get enough inductance with any reasonably sized stack of powdered-iron cores, but perhaps ferrite. I'll check into it. Thanks, Jim N7CXI ________________________________

A 1MH 300ma piewound choke should be just fine in normal operation and still give the amps fuse time to react. Just dont use some slow clunky breaker. Carl KM1H ______________________________________
