Hello All-
I have for sale the Manson Labs GRC-129 synthesizer set for the R-1147
{ R-390A variant by Manson Labs} receiver. There are two pieces of equipment
here that work together : { Listed Below}

Synthesizer, Electrical Frequency # O-1203 / GRC-129 by Manson Labs,
serial # 71
Converter, Frequency, Electronic # CV-1693 / GRC-129 by Manson Labs,
serial # 46

Both units are in nice condition.I popped the covers off and made a visual
inspection of each unit.They are clean inside and look very nice.I noticed
on the CV-1693 that the 12AT7 { near center of unit} was removed.The shield
is there.Not sure why this was done.Also, 2 of the Zeus fasteners on top
cover are missing on this unit.I surely will not power them up and they will
be sold as-is, please.
Anyway, I have no other accessories, cables, etc. I also brought back a
large amount of military manuals on this trip, will double check them in
case the GRC-129 manual may be there.
Thanks, Byron.
