[sci.electronics] The RCA 9-BX-5 Rides Again!

starin@mutha.dec.com (02/15/89)

This is a second response to the posting on the old RCA radio.

------------------------------------------------------------------------------- 
 
- Knowing the tubes used, does this help to date the radio?

-- Generally speaking, yes. The 7 pin miniature tubes with the 1.5V 
-- filaments were a product of WWII. However, with the introduction of the 
-- transistor in 1948, their days were numbered. Subminiature tubes 
-- filled in for transistors in VHF/UHF applications until transistors 
-- caught up but even they were on the electronics scene only 
-- briefly (except for surplus people like me).

- The street address in Holcomb would certainly be appreciated.

-- The one I have is old but I'll look it up tonight and post it on 
-- the net tomorrow. They also have a really neat museum in Holcomb 
-- (not far from Rochester, NY) where you can see all kinds of old 
-- radios (like an arc transmitter) - bring earplugs!
