Jack Deville Boost Tiger

Here's an op-amp based boost circuit from Jack Deville (Mr. Black Effects). He was kind enough to share his schematic a couple years ago on FSB. I stumbled upon it and thought it would be a good addition here. It should easily fit in a 1590a, and you can probably board mount the pot too.

  2. Sir what is "1-boost-3" in the diagram? Log of pot number 1 and 3? How about log 2?

    1. The pad for lug 2 would be that pad right between the ones for 1 and 3.

  6. Hi! Can I change the 51K resistor to a 47k one? I can't find one of 51k...

    1. Yes you can change both 51k resistors to 47k. Those two resistors are forming voltage reference (4.5v), so as long as they're both the same value it should work. Anything between 10k and 1M does the trick.

  7. I made it, with de 47k resistors and a 4558D. It sounds, but incredibly loud, and the potenciometer seems to have no effect on the volume. I checked the diagram and all is ok. Do you have any idea? Thanks!
