Mission Bell Model 19A Car Radio
#9

Hello everyone, 
As mentioned in my last post I was going to see if the vibrator / rectifier section could be persuaded to work to make this set "self sufficient". 
We have had some luck here. Initially while the vibrator vibrated , it  seemed  no a.c. was appearing on the rectifier anodes. Checking the  buffer cap across these anodes  showed it to be  very leaky. Replaced with a new 1000 volt  one a healthy a.c. appeared  when the set was powered up  and  with  rectifier plugged in  I measured slightly over 200 volts  between the cathode of the 84 and earth. 
The set is remarkably sensitive especially considering there is no r.f. amplifier.
I have mentioned that there are some differences between the schematic on radiomuseum and this set.The radiomuseum circuit shows a half wave rectifier only. This lends weight to the idea that my set is a later " factory improved " set.

Especial thanks to all who have contributed so helpfully  to identifying and tracking down the make and origins of this set. I'm hoping it will provide an interesting talking point at our next vintage radio club meeting.
