Could it be a J307? That's a VHF P-channel FET.ansil wrote:i have a motorola

The J307 comes in a TO92 case (not much help, really, as a large percentage of transistors come in those!).ansil wrote:got a link to datasheet. it could very well be that i coudlnt' find anything on it.

Why do you need to replace the device?

ok the j307 looks like suitable replacement for it. but no luck on finding it to-92 case. and i forgot to add that the previous one was in a metal can. i did however find the preamp schematic for it courtesy of lovely chaps at fender.
