    Bias JFET?

    Bingo! DMM was also partially to blame. Went to the store and got another one and R5 worked right away. Got it to 12.07. My ear had it a little bit too hot. thanks for the help guys... now on to Q2 + Q3. Hopefully Ill get those much easier.

    Bias JFET?

    That makes sense... My DMM must be a POS. 2K, 20K, 200K nothing changes but the decimal place... no reading. If I go to 2M I get a reading.. 1.235 nothing changes when I adjust the TRIM.

    ok wow... you are correct! i am an idiot. wrong resistors ordered and installed. Don't have any 1M on hand so will have to wait a bit to swap. thank you!

    Son of Ben (no sound when engaged)

    hi there. I've built up the son of ben twice now. both times i've had the same issue. signal passes thru just fine in bypass. No sound when on. I've read a few threads on here about bad jfets. My first time i got some off of eBay... 2nd time bought from mouser. Same results no mater the...
