[ARC5] Harvey-Wells AR-3a

[MICHAEL BITTNER]

Hi Dave,

I much appreciate your offer. However I also have that Sams. Eldon Meyer has pointed out that the Airadio SU-41D (https://www.radiomuseum.org/r/airadio_su_41d.html) is very similar to the AR-3A . However, its chassis layout and coil construction and placement are different from the AR-3A so I suspect that there might be some circuit differences too and I'm interested in what they are, if any. I have both receivers but only the Sams for the Airadio. The methods for RF/IF gain control and audio filtering are different from the 6.3-Volt versions due to no cathode element separate from the filament in the battery tubes.
Thanks Dave and 73.

Mike, W6MAB
