[Milsurplus] BC-654

Bob,

I used to have the connectors (both ends) but sold the last ones earlier 
this year.   I meant to ask Bill last week whether he still had any or not but 
forgot.  It's worth a phone call.

There are two common problems with the PE-104-A receiver vibrator supplies. 
 (a) you will almost certainly have to pull the vibrator and clear the 
contacts (the AC line and light bulb method is usually successful with these).  
(b) you will have to replace the selenium rectifier(s) (quantity and 
function depends upon which Order Number yours was made on).  If the filament 
voltage rectifier is the only one present, you may have to add a fixed resistor 
in series to get the filament voltage down to 1.4 - 1.5 VDC.  If yours has 
the shunt regulator, you don't need to worry about that as the shunt regulator 
will take care of it.  Otherwise, I've done several of them and had to 
replace only an occasional capacitor.
