Hi,
oops, typo, I mean NPN. Here's the circuit. I needed a 12-15v tone control so that's why I chose this.
What's the best npn buffer transistor ? Would I need to change the input bias resistor from 1k for the upgrade transistor ? Thanks !
I'm using MKP1837 Vishay caps in the baxandall-type tone control and Blackgate n caps for coupling. I've replaced the op amp with LME49720HA but maybe an AD8620 will work better.
