Anyone interested to build a TG1 clone ?

It loks to me like there is possibly a bit missing from festers diagram (which is the one that was posted before) where it has been stitched together.  If you look at VT16, the emitter of the transistor above, doesn't seem to tie into R47 properly.  Maybe there's another component ????

For missing stuff, it worth to roll some posts back.

I vote to realize a clone that's closer to an EMI original, too
About the transformes, I think that it is better to use a 1:1 configuration

Thanx to my friend for cleaning the old dirt from mom's receipe!
Now it looks like new, 80 years ago.

Those who interested in TG-1 progress, please send me an e-mail!

(no pm's, thing is too tired to check pm box and clean it up).

Here's some photos from my lab.
It is good rainy weather and Friday 13th here!

>Playboss,
you're doing it wrong:
first, you're supposed to say "email sent", and then you add a laughing smiley, not a question mark.
Then twenty others do the same, and we have a whole "email sent" page".

Quick question: is anyone able to verify the values of the A.O.T. resistors I'd posted earlier?


And again for the record: Email sent  :-\

The A.O.T. values differ from side to side and unit to unit. The very point of these values is to calibrate the product and then match it with it's twin. The A.O.T process from scratch takes 76 hours minimum.

Does anyone have any idea what the two output transistors are in the C******r unit are. Is there a modern equivilent to the ones in the schematic ???

NTE218 = 2N4898

NTE175 = 2N4910
