Can you tell where the rest are made?

Well, if alphabetic economy is needed, may I suggest switching to
Hebrew instead. Hebrew has only 22 letters, no vowels, and 5778 years
of experience and testing. For situations where vowels might be
useful, they can optionally be attached to letters as niqqud:
<https://en.wikipedia.org/wiki/Niqqud>
In all, Hebrew would make a suitably economical replacement for the
Kings English.
 
Another problem is conserving white space. White space is not really
necessary. For example, ancient Greek did not have any extra spaces
or symbols between words.

The supply of white space is limited and in danger of extinction. When
we run out of white space, allthewordswillruntogether.

I see there's one listed on ebay - not mine but I should have one according to an old database I have from my service days back then.
I do put some on ebay as I find them depending on condition etc.
I'll keep a look out for it but it could take some weeks to locate.

Try your basic Google search. Many times it comes up with a link to electrotanya. There is also a very very slight chance the hifmanuals or hifiengine has it.

Hi Dan,
 
I should have mentioned I am a retired service tech (many years) in consumer
products (TVs, VCRs, Stereos, etc.) repair.
 
The problem has to do with a long delay 30 to 40 seconds when you turn on
the Radio before you hear the sound. This happens when the radio
has not been turned on for several hours. If you turn on the radio in 15
minutes to a few hours after it was on, the sound "comes on" very quickly.
 
I know the technique to isolate the faulty stage. The schematic would save
me time (I won't have to circuit trace).

Agreed. However, I suspect that you will find that electrolytic capacitors in general will be the actual problem(s). Look for any swelling or signs of damage or leakage - you may not need the schematic after all.

Try preheating the radio. If it then comes on immediately you've almost certainly got a lazy small value electrolytic on the board.
 
If you have an ESR checker, run through all the caps after the radio has spent about half an hour in the refrigerator.
 
I still make an excellent living repairing consumer electronics, and using time saving shortcuts allow me to do so. Very few things these days has a full schematic for it. Most of the time I'm piecing them together from IC datasheets.

If it has a switching power supply that is where I would look for a bad
capacitor or more. If you have one of the SMD heat guns, play it on the
electrolytic capacitors to see which one makes it come on faster.

Does it require tubes to operate?
