Title: 2N5457 sub for Spacehard and Rotten comp.
Post by: mr_mwr on January 07, 2019, 09:27:47 PM
I'm just getting together a full list of all the parts that I need to order for my next few builds, and when starting a cart and adding everything in it seems that these transistors are basically non existent anymore. I did a few searches to see if I could come up with anything that discussed what transistors could replace these in the two boards i'm building but nothing I could see addressed it (maybe I wasn't looking hard enough)

Anyone have any suggestions for subs on this part for a GCFx ROtten Comp and the Lectric-fx Spaceharp?

You can use MMBF5457 and sot23 adapter board.

The jfet in the spaceharp works as part of a buffer, so pretty much any jfet should work (socket and experiment)
I've built a Rotten Komp/LoveSqueeze with a mpf102 and it works like a charm (not sure how critical it is, though)

If you can find a reliable source of toshiba transistors (I tend find those more easily), the 2sk118 and 2sk246 are sometimes listed as replacements (mind the pinouts, though)
