OP
There were, Linear Tracking to ’see’ the blanks space between tracks. Adjustable Sensitivity to successfully find the blanks. Most if not all P-Mounts. P-Mount was an industry standard: same size/weight/tracking force, And no alignment issues,

MyTechnics SL-J33 has become my ’loaner’ to friends having trouble with their TT’s. It has an AT Microlinear Stylus, everyone is very happy with the compact little fella’s sound. It is quartz locked direct drive with impressive performance, the model I was advised here to look for.

I was using it in my Garage/Shop system, but switched to the Sony Front Loader FL-1 (pivoted arm), so I could stack it, and ger my dual cassette and 8 track units back in that system.
Sony has unique headshells, an alternate adapter that allows standard 1/2" cartridges, which I was going to switch to after it arrived. Luckily it came with the adapter and best available Shibata cartridge already on it. Don’t think the seller knew what he had.
