You are right on the rpm's L.P's or long plays are 33 rpm's, 45's are the small ones that usually had a single on each side that were used in jukeboxes and then 78's that if I remember right came in a couple different sizes and had a wider groove than the others. I have 4 Peaches record crates full of albums I still listen to. I just picked up another Micro Seiki turntable. Albums just sound richer than CD/digital IMHO. Damn I guess I just gave away my age. Old enough to be an expert on 33's and 45's but not old enough to remember 78's. lol
