I saw a super clean 1951 Ford radio for $45, too bad I don't have a 1951 Ford! I noticed Ford still used octal tubes in 1951!

I'm supposed to be here for cars but radios keep popping up! Yesterday evening I got a GE clock radio model 535 for $15. It's a 6 tube radio with hand wired chassis instead of a PC board. No chip or cracks and the back is in great shape along with all knobs. Not a great color (marble maroon) but it's still a nice radio. I also found a like new 15 amp Variac for $40. Not sure I'll buy it as I already have four 5amp units.

Bendix built most Ford radios and was slow to convert to miniature but then probably no one other than maybe Delco had by '51... I have a '54 Ford radio that still used octal for audio output and rectifier... The other tube openings are large, chassis was no doubt punched for octals but have large 7 pin miniature sockets installed... The '55 Ford radio did have all miniature tubes... GM switched first likely because their vehicles introduced 12v systems in the early '50s, Ford finally switched to 12V in '56...

BTW there are Motorola radios for Ford as well, those may have switched a little sooner...

AFAIK, Delco started using miniature tubes when 12 volt radios were introduced, starting with the 1952 Cadillac radios. GM/Delco Radio used 12V6 output tubes and 0Z4 rectifiers up thru 1958, both octals.

I was going to mention that. The vendor across from me has all Chevy parts and had a NOS 58 Chevy radio with Octal tubes in it!

Yeah if it hadn't been for 12v vibrator P/S car radios, I doubt there would have ever been a 12V6, or 12X4 for that matter... Both of those were history shortly after the transistor output radios appeared in abundance for '57...

Did any other radios use 12V6 tubes other than Delco Radio? I can't think of any, right offhand.

My mother used to have a late fourties Chevrolet with a car radio that used PP 12V6 audio output tubes. That radio was a great sounding set. Great reception fairly good treble, and, excellent bass.
Miss that radio... The car was a tank.
What happened? My mother was stopped at a light, and, somebody jumped the gun, and, rammed our car. We survived, but, the car was totaled.

Not a 1940s she didn't, was no 12v car radios till the early '50s and Chevy didn't switch to 12v till '55(we had one, but it didn't have a radio)...

Out of curiosity I checked the registration for 12V6 and it wasn't registered till 7/9/52, so the earliest it would have been in anything would have been 1953 models... Interestingly the 12X4 was also registered 7/9/52, both tubes by Tung-Sol... Assuming Caddy switched to 12v for the '52 models(maybe 53?, I honestly dunno), they would have used a pair of 6V6 in series...

Tung-Sol regularly worked with the auto mfgrs, the low voltage tubes first used in the '57 models were all registered by them...

IIRC, Cadillac and perhaps Oldsmobile adopted 12 volt electrical systems in 1952. Buick in '53, and Chevy and Pontiac in 1955. Bill your mom's '49 Chevy likely had 6V6 output tubes.

While looking for EIA code info I dragged out my 1961 Sams index that lists car radios by mfgr, not just generic General Motors like the newer index...

Guess what???

Sams apparently didn't cover either the 1952 or 1953 Cadillac radios(maybe with model number those could be found in the generic GM list)... There's the six volt '51 & then '54 which used a pair of 6V6 with heaters in series... The '55 radios did use a pair of 12V6... In light of the '54 radio, I suspect the '53 did same and since '52 production was winding up approx same time the 12V6 was registered, it's safe to say that radio also used 6V6 in series...

That is interesting.  I rebuilt a radio for a '54 Cadillac Eldorado.  It was a WonderBar, with, IIRC, 9 tubes.  It had P-P 12V6 output.  I am not familiar with any GM radios with 6V6's wired in series.  This same '54 Cadillac radio was used in '56 Packard Senior cars.  The only difference was the face plate.  It even had the vacuum switch for the power antenna, ala Cadillac.
