I need a few 3sk type transistors to repair a Yaesu 736 222 mhz module. Is there anyone stateside that sells these? Thanks Mike

No luck with Digikey, Mouser or Newark.

Have you tried NTE to see if they cross to a more common 2N number or something NTE carries?  Most electronic supplier I used are able to get NTE parts.

Listen to EMO!  If you can't find an answer there.....you have the wrong part number.  Even if it isn't made or available, you will get information that might help you.

if it's in a tuned circuit area, you might have to diddlestick it with the appropriate test equipment to get full factory magic, even with the designed part.  all semiconductors are released within a band of performance, and that can vary wafer to wafer.  don't try this at home if you don't have the service manual and appropriate test equipment handy.

so I wouldn't be adverse on one of my radios to find the spec sheet, pick up on the major parameters, and work back and forth with the NTE replacement sheet to find a device with pretty much the same parms.

but if it's a discrete made in the past 20 or so years, somebody has overstock and will sell it.

you could also contact the manufacturer parts department and likely get one from them.  3sk type MOSfets at low power are still around.

Remarkably Yaesu had them $1.50 each. Bought new screws for 2 cents each. Received in 3 days. Great deal.
