Want to build a preamp to go between guitar and guitar amp.
would like to use 90 volts for B+ , this would be a very simple one
dust need the componen value. I sure would like to know how to
use the tube data sheet so I could design it myself. Maybe skunking
could do video on how to use the data sheet. Keeping my fingers crossed 🤞
Thinking on using a mod like this for the B+ voltage. It’s small.
