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
