Ar77/GR10 modifications made in mid 1960's.
Hi all!
I've recently aquired a receiver of this type which has been modified back in 1966. Basically the original octal tubes have been replaced with B9A and B7G types like the ECF82 and EF183. It was modified (officially I think) in New Zealand, but the mods may perhaps originally come from either Australia or further overseas. Has anyone come across a schedule for this modification. I've already got the RX working but I would like to clean up some of the now redundant wiring and this will be much easier with such data. BTW it has the original S meter. Any help greatly appreciated. 73's Cliff Wright ZL1BDA. |
