Re: MF/HF Receiver type R/75/WRDV/3550
In answer to my earlier question about CV valve types, cruisinradio tells me that CV4055 is 6132 and CV4058 is M8080
Another interesting feature of the construction is the tuning lock lever, which confirms it being intended for a marine environment. I still haven't worked out the 1st IF or the 2nd conversion osc, but I presume that's a little bandstop filter at the aerial input to the tuning circuits which will reject the 1st IF
There is a crystal unit, unfortunately with no xtal on mine, but it seems to provide a single crystal channel which would have to be tuned manually by the bandswitch and tuning control
I think the tagstrips are rather cute but I hope they will withstand careful component replacements
Does anyone have a picture of the associated PSU?
