I have inherited a 1966 Silvertone 1484 Twin-Twelve that works but is in pretty bad condition, and I've decided to fix it up. For various reasons, I've decided to make nice walnut cabinets to house the chassis and speaker cab, and convert the hard-wired tether between head and cabinet to a regular output jack.
I think I have the basic soldering skill necessary to install the output jack in the chassis and an input jack in the new cabinet I'm building, but that's as far as I'd push my soldering/wiring expertise. I would not feel comfortable converting it to a grounded 3-wire power cord and modifying it to use the new ground wire. I would absolutely not feel comfortable replacing resistors or capacitors.
Am I being an idiot thinking it's okay to do the output jack conversion but no other electronics upgrades/repairs? I think I may have a professional amp tech recap it and do the ground conversion in the future but I really want to get the amount I've already bitten off accomplished first.
Before anyone asks, I never intend to sell it, so ruining its resale value is not a concern.
