Howard Car Radio Model HA6 1936 - Antipodal - 08-25-2024

Hi Everyone, 

A friend has given me a Howard Model HA6 car radio - a set which has an interesting history , the more so for its turning up here in New Zealand.

 (Because we here in N.Z. have a lot to do with our Australian neighbours I originally searched there - and there was in Australia a Howard Radio Company. but they seemingly built only domestic radios.)
So try the U.S.A. and the Howard Radio Company of Chicago.

It dates to 1936 apparently . The schematic is in Riders 1937 GHI page 255.It uses a little bias cell, apparently to bias the triode section of the 75 1st. audio.As original the output tube was a 6B5 working into a push pull output transformer, but now replaced with a single ended 6V6. I haven't explored the output transformer yet. The holder for the bias cell is empty so what the arrangements for biasing the 75 (if any ) are ,also awaits exploration.It uses a separate oscillator tube (76) and a synchronous vibrator.

 But sadly like so many car radios the head unit is missing.
 
Would there be any one on the Phorum who has such  a   set  ,complete , who could upload a photo of their set so I can see what the head unit looked like? Or someone who could direct me to an advertisement in e.g. Radiocraft or similar to get an idea of what the head unit looks like?
Thanks everyone and all the best ,
Antipodal
