Is there a 2N# for this transistor. I could grab one at my shop if I knew.TY

Look it up in the transistor substitution guide.

If you were nearby I'd give you a few, I've got a ton of those. With parts being harder and harder to get locally I tend to buy large lots when I order a certain part. I'm starting to become a parts hoarder. Hopefully you can find what you need to get it back on the air.

Wouldn’t 2SC945P work as well or just plain ole 945? I’ve probably got a metric ton of those things in the junk bin in old radios.

I found no 2N sub for it though I only looked for like 15 seconds cause I’m in Alaska hunting wolverines.

Thanks to everyone who gave advise on transistor, I did find them online at mouser and digikey 34 cents a pop. More to ship then the bloody transistor. I should have looked before posting. Sorry, you guys are the best....MM

I’d be careful of where I bought them, I buy a good bit from Mouser also. I’ve got a bunch of them that were worthless. Put them in and the radio didn’t function correctly, pull it out and put one from a junker in, worked fine.

The good old 2N2222 will work as a sub in most applications. If it is used as a switch, it will definitely work. As an amplifier maybe ... maybe not. But cheap and readily available so worth a shot.

The plastic-body 2N2222, or "PN2222" has specs that are pretty close. Just remember the pins are not in the same order.

The '945 is E-C-B, left to right, leads facing down, flat towards you.

The '2222 is E-B-C, oriented the same way.

Can't just drop it in a circuit board oriented the same way. The "C" and "B" pins have to be reversed. Only a little clumsy.
