Hi LektroiD,

I don't know about equivalent FETs, but Banzai has the 2n5461 p-channel FET here:

I hope it helps
cheers

i took a look at my conversation with scott stites and thomas henry from the beginning of this project, and if i got it correct any P-Channle JFET should do. you could use a socket to be on the safe side.
thomas' goal was to have curcuits that don't use rare parts. and i know scott used a NTE part.

BTW if the transistor is only 0,24 it is not a rare part, i would guess. you get it from reichelt.de, and they are not known for stocking rare parts... maybe it is just that P-channel is not that common as N-channel in general.

someone over at muffs is going to try different p-channel jfet's, so we will know more soon.

I know this is a ridiculous question, but on the silkscreen the presets are shown to be a particular orientation. Is this necessary? I ask as the 25K ones I have are 1-turn and the dial is facing one way. I know I can also use 50K, I don't have enough spare...

I'm pretty certain of the answer here, but just wanted confirmation, just in case there's some magic ogre lurking in the wrong orientation...

no. it doesn't matter. i myself mounted them all headed into the same direction, just for the asthetics...
