I have a 1A, Serial #331, an early one, and another later one with WWV.?
I didn't realize that the original version did not have a crystal calibrator (I knew it didnt have WWV) until I opened them both up for recapping.?
The "newer" one also has a couple of sub boards, the original does not, though the components seem to be there.?
I don't have and cannot find the manual or a schematic? for the older unit, just for the newer one from BAMA.?
My question is does anyone know what the WWV mod, (which could be performed by Drake) consisted of? I assume it was not a difficult mod, and that the bandswitch has another contact for WWV. I have replaced the tuning dial with another I had, which has the WWV marking. Was thinking of adding the calibrator and WWV mod, but since no schematic of original old version its not obvious what was added. I have a third unit Which works but missing knobs and face place, its a shame to use it as spare parts.
