The SL65B was a fully auto version of the famous SP25mk3, so any solid 2g tracker should be fine - Stanton 500V3, Pickering XV15-VE, AT95E, Ortofon OM5e or 10 (if the arm is a good one and everything is clean and free, 1.75g tracking *should* be achieveable on these). Shure M55E, M75-EJ/93E etc...
The Tetrad may be a ceramic or crystal type and if your amp won't take a magnetic style cartridge, you'll need a phono preamp for the cartridges suggested above...
