I have maybe two to three thousand LPs. A bit of everything but mostly Jazz.
I have maybe four or five hundred 78s. Stuff from the 1920s up to the mid 50s, most of it post-WWII. My dad's collection, which is mine now, forms the core of this. I have old-timey country, 20s British dance bands, Swing bands, Jazz, Rock and Roll, and DooWhop.
For 78s the best cartridges are Stanton 500s and their Pickering clones. Esoteric Sound offers some the best and most affordable 78 styluses for the Stanton 500s. They are truncated (no point) elliptical styluses of varying sizes. They ride the grooves in an area where the old steel styluses did not. The truncation means they don't bottom out down in groove where all the decades of rubble lie. The varying sizes are because sometimes you have try different spots on the sidewalls of the grooves to find the sweet spot with the least amount of wear and also because 78s are anything but standard - no standard groove widths, no standard (exact) diameter, no standard speed, and no standard roll-off equalisation curve. Esoteric also offers an affordable entry level phono preamp for pre-1955 recordings, 78s and Microgrooves - it has a generic one size fits all roll-off curve but it is quite effective. Nice. I have not gone off the deep-end with multiple styluses but just have the most generic one - good enough for me.
https://www.esotericsound.com/index2.htm They are the descendants or purchasers of Rek-o-Cut, a company who made reasonably high-end HiFi turntables up to the 50s or 60s. They also made the cutting lathes for cutting the lacquer masters for records.
Old Dual 10 and 12 series turntables make good platforms for 78 playback. I used to rebuild them myself until my eyes grew too weak for the small close work. There is seldom a lot wrong with them - mostly it's just cleaning contacts, lubrication, and new rubber parts. If you like doing this sort of thing, there are a lot of online resources. If you don't, there is almost always a Dual turntable freak in any town of any size who buys them, refurbs them, and sells them on. Look on Craigs List.
