Among the appreciations of DIYers is stuff that works simply, well, and cheap, not necessarily in that order. 

This project is an effort to assemble these elements into a discrete gain stage that can be used as the front end for modest power amplifiers or as a general audio gain circuit.

What's included?

• Pair of circuit boards
• 12 matched J113 JFETs
  
• 2 KSA992 bipolars
• 4 resistors matched to the JFETs
