    Hi all,
    I am building a Mojotone tweed Princeton kit, and have a question on the OT. It's an NOS OT with the common soldered to the casing. If I'm reading the schematic correctly, since there is no common wire available for the speaker jack, I can just connect the speaker jack common to ground. My question is, does this cause any issues with noise (assuming of course that it is safe to begin with), and where is the best location to ground the speaker jack.

    Any input is appreciated.

    If I remember correctly, the “ring” of the speaker jack is already grounded to the chassis (on the originals).
    Solder the wire from the O/T to the “tip” terminal.

    I’ve built a handful of amps like this without any trouble.

    It’s grounded to the chassis because it’s screwed down to it. It doesn’t require a ground wire.

    Wow, in hindsight that seems so obvious. Duh!

    Thanks for the help!
