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

Hi everyone, I'm pleased to report that this set ,albeit without its head unit now goes and goes well. What I thought was a 6V6 turned out to be a 6K6 and the 75 had been replaced with a 6Q7. The vibrator (synchronous ) took some persuading to go but has started reliably ever since. Distortion caused by a leaky coupling capacitor to the grid of the 6K6 was an initial worry but once the cap was replaced it goes well.Overall it has been a pleasing repair,
