Hi C4R0, I was also looking for MRF150 transistors.

Search eBay every week and you will find some second-hand ones available which you can desolder from RF amplifier boards. I think one is even active at the moment:

http://cgi.ebay.com/Lot-Of-3-RF-AMPLIFIER-BOARD-Using-MRF150-MRF148-MRF134

Just curious, what is your application?

Thanks for the link. I saw this auction, but $150 when i need only one transistor is a bit too much for me wink My dad is repairing a CO2 laser power supply (1kW @ 40MHz, cool amazed ). Looks like one of the mosfets is dead and i have to replace it.
