Pepperbox / Volt Thrower - 18v -> 36v!

[megabelkins5000]

I built an Effects Layouts Pepperbox awhile back that I love. I just learned today that the Volt Thrower, of which Pepperbox is a clone, can take an 18v power input, and I am wondering if the Pepperbox can do the same. Seems likely, but I'm not certain and I don't wanna kill the thing. Help

If you used a 5817 and a ltc1144, and caps rated for the higher voltage, you can try.
Note, it is running at 18v. +9/-9 rails.
Note that +/-18v is the maximum rating for both the 1144 and LM308/OP07s.
So, you would be running the circuit at it's absolute maximum and the 5817 is a 20v diode so if your power supply spikes...

I'm going to bet that position 6(no clipping) is the only spot you'll get much audible change. In every other position, the hard clipping is going to dominate, regardless of headroom of the gain stages.
