WTB: Info on 75A-3 Product Detector ER

[Bob Rinaldi]

Hello:

I'm looking for a copy of the article in Electric Radio for the "no
holes" 75A-3 product detector.

Will be happy to pay for photocopies.

Thanks,
73, Bob

What issue is this?

Tell me more about this device?

I am looking at an outboard product detector for my R-390, and have been
idly considering some of the sheet beam tube designs. If there's one
out there for the 75A that I could steal and use as an outboard box, I would
be very interested.

Me too! Do you have an issue number for this? I am sure we can order the
back volume.

I don't have that info, but I did a product detector mod to my 75A2 long ago,
and it might work in the A3. If you don't find what you are looking for, email
me if your bfo tube is a 6BA6.
