Hi all!
The TU has found a new home...
Jack was rite, he was likely the only one to have
seen it, as it was not found in the normal
RTTY/Teletype haunts...
I was going to pass on it, but realized the treasure
trove of hard to find costly parts in this well built
TU!
I gess I have a penchant for these old relics
of yesteryear, and enjoy messing with them...
It is for sure a W2PAT design, and from what
I can see in the fotos, the original builder
put a lot of quality in the contruction...
The only downside of if it all is the TU is likely
set up for the old 850hz shift, and I am not
sure if the slug tuned coils can be padded
enuf to make it work with the 170hz shift...
I'll have to play around with it a bit to see if
it is possible...
I got a similar W2PAT unit from Jim awhile back
and still working on it in spare time...
It appears the orginal owner strayed somewhat
from the circuit as designed, so it needs
a bit of "Reverse engineering"
It is different in as much as it uses a 255 relay
to key an external power supply and loop...
This one uses a 6Y6 tube as a magnet driver...
Tks Jack for bringing this item to our attention...
Cheers!
