Circa '46 Emerson portable tube radio

[radiotvnut]

Here's an interesting Emerson portable radio that I recently picked up. It must be one of the better models, since it has a 3-gang tuning capacitor and RF stage, as well as dual audio output tubes. A 50B5 output tube is used when the set is operated off of AC power, probably for greater volume and better tonal quality. When operated on batteries, a 3Q5 output tube is switched in circuit. Here is the schematic: http://www.nostalgiaair.org/PagesByM...8/M0004628.pdf
