In a prior thread and some related 'now what' questions, y'all helped me figure out a buddy's ?1955 Gibson GA-9; octal preamp, parallel single-ended 6V6s, field coil speaker, all original. A few 'before' pics: With good advice here, we decided to do the minimum to make it safe and playable, no external work, etc. Other than new resistors to replace a 470 and a 220K that had drifted badly (both were floating over tube sockets -- the PTP here means almost everything is), most of the revisions can be glimpsed in the overhead. SJT power cord with strain relief. DPST hot/neutral switch. Stuffed new Nichicon 22uf/50V inside the old bypass caps. New filter caps with split grounds. And a lot of dust and debris removed. The PTP wiring made revisions tricky, since the 3 non-recto sockets essentially do all the work of a board; many socket lugs have up to 6 wires attached under an overhead defensive perimeter of wires and floating components. The whole chassis is narrower than the board in a small tweed: 3". Most of the resistors were surprisingly intact in value. All voltages came in nicely. I still need to put a p-clamp on the power cord and tighten up the springs in the sockets, which may be the source of some occasional static on loud notes. But it sounds extremely sweet -- awesome tone, in fact. I can add a few details later, but first I'm gonna complete the last few steps and then let my buddy give it a test run. Thanks to all of you for your help on this.
