[MRCA] BC-611 (SCR-536) Restoration - Experience/Advice Needed

[Garret Scott]

I’m starting on restoration of several BC-611F’s.   

 

Any advice from someone who’s actually done it?   

 

I’ve googled it, and come up with nothing, other than the TM and a post on how to make a battery.   

 

All of these are Mid 1945 Galvin production, appear completely original, no LSD overhauls or any other sign of repair since originally manufactured. 


So far, all appear to be mostly inoperative in the same way.  i.e. , there is some white noise in the earpiece, the LO is running on freq., but the IF seems pretty much dead.  Injection of 455Kcs does nothing unless I pound the detector grid with lots it.  AF amp seems to have some reasonable gain.  

 

I have not checked nor replaced any caps, although I see a few micamolds in there, so am naturally suspect, and will be replacing them.  

 

Thanks,

Garret
