Nuvistors were also used in the IF of a APX-153 Doppler ground speed & drift angle radar on P3B aircraft. Fred KF4QZN ----- Original Message ----- From: John J. Riddell Sent: Wednesday, March 24, 2004 8:37 AM Subject: Re: [Repeater-Builder] Re: Motrac / Solid State Tubes These devices were sometimes called Fetron's. We used them in 43A carrier
units in the Telephone
Central office in the early 70's to replace vacuum tubes.
They were 7 pin devices in metal cans and one version as I recall worked
well as
a replacement for a 6BH6 tube in the first IF of a GE progress line
receiver..
(Hams are resourceful people).....
The nuvistor was a different device, it was found in TV tuners of that era
and was developed by RCA.

| Perhaps the device referred to is the Nuvistor?
|
| These were used in VHF applications. [e.g. 6CW4] They
| are metal and don't look all that different from early transistors.
| The size is similar also, the Nuvistor is 0.400" dia. and a TO-5 is
| 0.335" diameter.
