Have you had it working?
It is powered up and playing very well as found and using the 77 year old "C" battery. It is driving a speaker with good volume from only two 01A’s. It receives many US and Canadian stations and its performance makes many of my 20’s radios look poor.
I have the front panel, tuning caps and coils and the audios only from a Grimes Inverse Duplex. This radio is getting up my interest in homebrewing the rest of the Grimes.
