Item History & Price
| Reference Number: Avaluer:1174447 | MPN: 1304-B |
| Brand: General Radio Company |
General Radio Company Type 1304-B Beat-Frequency Audio Generator, unit serial number 2750. I was not able to find a date-of-manufacture on the unit, nor was I able to find a serial-number date reference for this model. I assume it was made after 1960 or so.
All the tubes appear to be in good condition, none have gone gassy, those with chrome spots are still bright and shiny. I did not remove the tubes and test them because I do not have the facilities to do that. All ca...pacitors visible from the underside of the chassis seem to be original and untouched. A manual for this generator is available here: http://jptronics.org/GR/GR1304B/GR1304B.pdf
It bears an inventory label from Jensen Sound, which is interesting provenance.
