I am in the process of going through the RF deck on my 1952 Collins R390A. The first thing that struck me was the chassis darkening in the subcompartment under HR202. As we know the heater is *on* all the time, cooking the Xtals. All the small components there showed the effects of lots heat with runny wax on the micas and darkened ceramic disc bypasses.
One strange finding was R211. There was a 82K resistor, but all the manuals called for a 8.2K resistor. My question is: is this just an innocent error?
Thanks
