**Sorry, I don't. But it is worth fixing. I had one in my FC Holden. Best
damned AM radio I've ever owned, except for my all valve TRF.

"all valve TRF" now Trevor my friend, you just dated yourself with that one.
One day in class my instructor held up a transistor and said "don't worry too
much about these, they won't last".  How's that for dating.

Thanks for your reply

**Probly was. I purchased my FC in 1973. I fitted the radio (which I bought
from a wrecker) soon after. A heavy, push button affair, with (I think) an
AD149 mounter on a corner. Excellent AM performance. When I sold the car
(for $50.00) I wanted to pull the radio out, but the guy who purchased it,
wouldn't buy the car without the radio.

**Probly. A neighbour gave me a chassis with a 4 gang tuning cap and all the
inductors. He then provided me with a New Zealand electronics mag, with the
design of the thing within. All the hard work was done (chassis punching,
etc). I just found a bunch of resistors, caps and valves and assembled it.
It reached the point where I could easily tell which turntable the radio
station was using (due, either to mis-alignment of the arm, or a worn
stylus).

It's been a while, but IIRC the model number will be stamped in the
case, and will look something like the one I quoted.

I've got a good collection of circuits from the era, and earlier, and
may be able to come up with something if you can can come up with a
model.

Thanks for your reply John H, the number F18117 is stamped into the case near
the power transistors.  They are Anodeon AT1138 and others are 2N406, 2N410B,
2N410E, 2N412, 2N591 and one I can't read which I think is an RF amp.  Also, I
believe the polarity to be neg earth.  Some helpful Harry had connected it pos
earth hence the need for a cct dia.

The model I quoted has AT1138's in push pull for the output stage but
none of the others match.  It's also a dual polarity set.  The RF amp
is AT313.

I don't have a date for it and there were a number of models available
at the time.  Without a model number I'd have considerable difficulty
locating anything other than the one(s) I happen to remember.

Most of the vintage radio specialists (and many a good reference
library) will have the original *Australian Radio Service Manual* I
referred to (I'm a little surprised google couldn't find it) and are
probably happy to sell copies of individual circuits.  The original
manuals (which I don't have) were issued by year, so they ought be
able to track down the various models by the year of manufacture.

You don't say where you are but one source I have listed (and can
recommend from past dealings) is Resurrection Radio at Prahran (Vic).
The number I have is (03) 9510 4486.  Might also be worth a google.

Thank you John H for your help, you have given me a number of clues for which
I'm most grateful.
Google did turn up a source of the Australian Radio Service Manual but for
$110.
The local library is not big on electronics so I'll try the big smoke (Brisbane)
soon.

Thanks again for your help

It's actually the *Australian Official Radio Service Manual* (my
earlier mistake) which may help if you're using a library (or google).

Most of my circuits from that era came from the SA Public Library back
in the 1970's when I lived there.  I'd guess most state public
libraries would still have copies filed away somewhere.

Thanks John H, I've only done online searches and there's plenty of stuff in
council and state libraries if you like cars etc.  I guess a pickup of vintage
radio is pretty low on the list.  I'll do a run on the state library here in the
next week or so.

All the best

You might also try the local TAFE library.  Even if they cannot help, you
can use the index system to find the location of any copies of what you are
looking for.
