Mullard red jacket GET 104T
 

I'm looking for some data on a Mullard germanium transistor - GET 104T. Are these useful types?

Re: Mullard red jacket GET 104T
 

GET104= AC126, ASY59, 2G303, 2N2429

The "T" suffix is not mentioned in my old book.

Many thanks indeed.

Here is some data which may help, but no T suffix

Excellent Martin. Thanks heaps.

It's actually a GEC transistor. GEC and Mullard/Philips had a joint venture in the early 60s making transistors, and this resulted in Mullard branding on some GEC types.

The GET104 isn't anything fancy, it's just GEC's answer to the OC71.

The name Broadstone mentioned in the Thumbnail in post #4 was the name of the mill where the GEC transistors were made in Reddish in Stockport if my memory serves me correctly. I remember the minute pieces of coloured sleeving on the wires of GET 113 and 114. Mullard and/or Philips had a facility nearby at Hazel Grove. Peter.

Please find attached a PDF copy of the GEC Data Sheet for the GET104 Germanium Industrial Junction Transistor, all 32 pages of it. This is not the "T" version of the transistor but may be of some use.
Note I have increased the size of the document by 35% to fill an A4 sheet, it also helps me read it.
Regards Stan.

Many thanks for all the replies gentlemen. I'm very grateful.
