Photos of Available Items

Below are some photos of items that will be available at this years RadioActivity Event, either through the auction or the raffle. More photos will be posted as they become available, so check back often.

Fada "Temple" Radio


This Fada model 652 is from 1946. An exquisite example of Art Deco, the radio has a catalin cabinet. How about that butterscotch trim. Look for this radio in the main auction.


SNR Excelsior

This radio is a chromed SNR Excelsior model 52. It was made in France, dated 1952. This multi-band radio has all the bells and whistles: tuning eye, original sombrero knobs. Restored in France, it is in good condition. Such a fine radio, it was the basis (almost identical) for the Russian "Red Star" radio of 1954. Look for this radio in the main auction.


RCA Model 128


This fine looking and perfectly playing RCA was donated to MAARC for inclusion into this year's auction. You may get to hear it over the course of the weekend. The radio has two bands, AM and SW. It will make a fine addition to anyone's collection.


AN/USM-118B "Cardmatic" Tube Tester with Cards

This unit was the end-of-the-line as far as Navy tube testers go, and saw service clear into the 1980's. A Hickok made 'cardmatic', it comes complete with an extensive set of cards (all that were issued with the tester), a zener diode test unit, a complete set of calibration cards, and a reproduced manual. This test set is fully functional and was just calibrated using the calibration cards and zener test unit. It will be made available to test tubes at Thursday's tube and ephemera auction. Donated to support this year's raffle, you may want to purchase a few tickets so you get a better chance of taking it home.

Replacing Power-Cord Resistance Elements or Ballast Tubes

Have an old radio that used power-cord resistance elements or ballast tubes that are no longer available? Ed Lyon has taken Charlie Rhodes' equations for determining how to replace those with modern-day capacitors and created some charts to guide your repairs. Published in the September 2017 Radio Age, they are provided here for your use.
