what's the smallest (literally) boost stage i could hack on the end of this?

[idiot savant]

Anyone ever use the TO-92 version of the LM317 as a boost stage?  The signal input goes to the adjust pin, the source pin goes to the positive rail and the output goes to the output.  The output will be 1.25 volts above the input, so bias the input appropriately and add a pulldown resistor at the output.  Use capacitive coupling to the output and add the normal pulldown resistor.

Joe Davisson had a lm317 fuzz on here 10-12 years ago iirc. Pretty nifty idea.

Tiago had a couple of boosts (Beast Boost) using the TLV431 shunt regulator.

wow.... mind blown. isn't that a voltage regulator?  that sounds kinda cool!!!!

i took the dang thing out last nite, and it crapped out by the time i got it plugged in lol....

thirty pounds of shit crammed in an 8 lb sock

i may give this idea a go too on the next one.
