Subject: Alpha 86 / 89 Plate RFC
The Alpha 86 and 89 use a Home brew relay/Flapper scheme in HV path to short
out part of HV Plate choke
RF Parts sells RFC that all indications can replace the existing choke and
remove the flapper
https://www.rfparts.com/rfc3.html
Has anyone changed out the plate choke to eliminate the shorting flapper?
Saw article where author rolled his own and removed the flapper
