    3. Did some reading before I built mine and 1N4001s came up as a close replacement. Sounds great!

  2. Question for ya. Is this naturally a low output circuit. I’m not sure if I did something wrong or if it’s the way it is. If I turn the volume all the way up and the gain all the way down it is way below unity. If I turn the gain up I can get just above unity but very overdriven sound. Is this nature of the beast. I have read of some people complaining about low output on the original. Just want to make sure I didn’t do something wrong. Also should should I be biased about 4.6. I’m not , I’m at about 2.6 on all 3.

  3. Got it worked out. Had a bad transistor. Ended up using J113s. I kinda like them better.
    Eros all preference.

    1. Thanks for the info. Good to know that J113 works fine since the stock starnsistors is pretty rare nowadays.
