    Barn Find PL400

    Did you properly swizzle the leads of the KSC1845 since they do not match that of the TIS97 devices? Both TIS97 and KSC1845 have non standard pinouts

    Barn Find PL400

    Have you CAREFULLY measured the collector of Q2 and Q1 when you find it in this condition? I suspect you may have upset the stability of the amp when you subbed the KSC1845 devices instead of the original TIS97 devices used? Q2 C should be much lower than Q1 C.

    Barn Find PL400

    If it latches up with an 8 ohm load, it will blow the fuse. If it latches up without a fuse, it will just latch up.

    "Ramblin' Man" Has Passed at 80 Years Old

    I saw the Allman Brothers when they were still intact sometime in the very late 60s at Hudson Valley Community College, warmup band was Jay Giles band. They were both still undiscovered enough at that time to be playing at a tiny junior college venue like this.

    I Need a Part

    It may be that Hexis removed one of these when he converted Gibby's original PL700, as he did a complete chassis conversion as part of that effort. Worth asking.

    Help with transistor substitution on PL400

    No, the germanium devices need to stay germanium for the current limit to work properly.

    Help with transistor substitution on PL400

    Or get a real board with capable devices on it rather than those marginal TO-5 devices :-)

    Help with transistor substitution on PL400

    Use the 2N3439 and 2N5415. On your Q4 question, none of us were there so we would only be speculating. Q4 is a low voltage application, vs. Q3 which requires a high voltage device. Beyond that?????
