Title: 2n5172 Substitute/Equivalent
Post by: Shrtyska9 on August 18, 2014, 08:49:37 AM
Hey guys I am trying to finish up a systech od build and the doc calls for a 2n5172.
I have searched high and low on Google and cannot seem to find an answer for a substitute tranny so I figured ask the knowledgeable folks of the madbean forum.
So is there a more common substitute or should I just order one?

Thanks in advance guys.

Richard

2N2222

Both of these are listed as "Very Close" replacements. Be sure to check pinout  ;D

Worked like a charm despite making a few bonehead mistakes (connected tip to ground and sleeve to in, and the power jack backwards.) lol.

Thanks again man.

Well I can do a demo and a gut shot but its in the enclosure i use to test boards before they get a permanent home. I am definitely slacking when it comes to build reports though.  :-[ :D

Basically this thing sounds like the Harmonic Energizer run into a fuzz pedal. It nails the tone on Pojama People.
