Update: I picked up on the cheap (I was the only bidder) on feebay a lot of 30 record player serviceman items (including several cartridges, needles, a needle tracking weight scale, tonearm wire, cartridge mounting screws and spacers, a desoldering bulb etc.) for $9.99 plus shipping and one of the cartridges in the lot happened to be a NOS Sonotone 2T Cartridge so I should be good to go to get this unit fixed up the rest of the way!
