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.
