[time-nuts] Fluke (Montronics) Model 207-5 WWVB Receiver/Comparator

[SAL CORNACCHIA]

Hi Bill,
 
The pot appears to be working properly and have adjusted according to alignment, the problem is the plug-in board revisions my is a high serial number and the components are different than the manual and do not know if they are right or wrong, I acquired the receiver used with many issues, managed to repair some of the but cannot find the proper manual with later revisions, do You have a manual with later revisions or check the revision numbers on Your.
 
Thank You
 Best regards,

My experience with an old phase-locked receiver was that the trim pot
for the PLL was way off. Tweaked it a bit, enough to break a film of
insulation, and the PLL started working. Wasn't the only problem, tho.

This is an OLD unit (<1970s). I have one. In your shoes, I'd check all the
axial electrolytic capacitors and Tantalums first thing. You might just
find it starts working.

BTW, I think Artek had a manual in progress.
