What Germanium PNP transistor do I use?

*****Oh no, Phil. Not at all. But I have no idea how to post it
online. Am I supposed to
scan it in first? Or....?

Yes you would have to scan it or get someone to scan it for you.

You could post it on various sites that host image files for free. I recently
used rapidshare to do just that for example.

US cars were 12 volts a lot earlier than that. My '61 Ford Galaxy was
12 VDC. I could dig through my collection of Sams Photofact car radio
manuals to find the exact dates, but 12 VDC was in wide use when car
radios were still using vacuum tubes in the US.

My father's 1960's Ford Taunus 12M was 6V. This series was somewhat
comparable to the Ford Cortina and probably named after the German
mountain range "Taunus" near Frankfurt. 12M meant 1200cc, 15M was 1500cc
and so on. AFAIR they were built at Ford Motor Company in Cologne, Germany.

I think that VW was the lone holdout in the switch from 6 to 12
volts. I used to sell and install a lot of 6 V to 12 V converters for
'40s and '50s cars in the early '70s. I repaired a lot of them, when the
moron hooked it up wrong and took out the pair of Germanium power
transistors. There was also a 12 V positive ground to 12 V negative
ground converter for a few oddball models.

The 12V auto-electrics were well and truly established in the period I
remember, and don't forget the first ever transistor radio used a 22-1/2V
(tube) hearing aid battery - presumably the PP3 hadn't been invented yet.

ISTR 12 volt tube sets with synchronous rectifiers.

No, those are fairly small:

But in their days anything that carried the name Tektronix on the front
panel was big bucks.

Mine was free - a company I used to repair monitors for decided to downsize
and concentrate on their core business (keyboard refurb), they had a pile of
scopes in the corner which they donated to me. The lowest was a Trio S/T
10Mhz and the best was the 465, all of them had some fault or other, the 465
sometimes "goes to sleep" - it wakes up with a gentle pat on the side so for
the time being I'm content with that rather than mess with the insides if I
can get away with it.
