Looking for info on an old obsolete RF transistor

[loosecannon]

The only thing i can find on this transistor is a chinese fake on ebay.

the part number is: 4104P1 and i think it might be a motorola transistor?

it's a "pill" style transistor with a stud on the bottom.

I got two of these, never installed, in a box of CB junk a friend gave me.

this was actually a very good box of "junk" as it also included an old palomar TX100 amplifier that has the 80-10 bandswitch on the back, as well as an outcom "the force" two pill.

thanks for any info anyone can offer.

Is it like the 455A with a stud mount?

Hmm
Only thing I saw looks suspect, general chicom with no real data about the device.
What's it going in?

yes Jeff it looks just like a 455a stud mount. the white cap is 1/2 inch in diameter.

i don't have any plans for it, i am just hoping to find out what amps it might have been used in, and what they might be worth.

i havent tested them yet but i have no reason to believe that they are bad since there is no solder on the tabs.

not even RF parts shows this one!

I have a motorola book at home that might list it. i'll post back if i find anything in there.

Been almost 50 years since I worked for a Motorola land-mobile authorized shop, but that number could be for a Motorola FM 2-way radio. They would print only the last four digits of a 8-digit (IIRC) part number onto the transistor. Cross-reference books would tend to include the whole full-length part number, but the abbreviated four digits printed on the part not so much.

When doing a repair on one of these, you knew the radio model number and had the factory schemo and parts list on hand. That's where the full-length type number would be found, so you could order them from Motorola.

But a naked four-digit? Good luck. Needs someone with first-hand knowledge of the radio it was meant for, maybe?

thanks for the input nomad!

it looks like this might be a GE transistor?

it seems to have been used in the GE Mastr II repeaters.

Here's what NTE says will replace it. Low-band (30-50 MHz) 40 Watts. Only 7.5 db gain? Hmm. That would make it closer to 10 db at 27 MHz, maybe?
