Hi Scott,

A 3 pin jack female 17 mm outside diameter was used by Geloso to connect the
cord of a microphone into a 3 pin male socket 20 mm in diameter fitted into
the front panel of a Transmitter G 4/225 in my hand.

In general Geloso uses the above non standar connector in all models of
RX/TX  for radioamateurs early in the 1950-1960

If this is your case I can send to you a scanned copy of the original
schematic diagram.

73" de

> hi, maybe some of the older chaps might remember this kind of jack. I
would like to know where i could buy one and if someone could send me a
diagram how to make a cord to go from the geloso (3pin out-put plug) to a
1/4 mono jack. Hope all had a very good new year.  73 de ve6itv  Scott
