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.
