Hello everyone. Recently picked up my first deck, a Lasonic TRC-931 2nd Edition. Seller says they bought it in 1986 from Sears and had it hanging in his out building the entire time. I love this thing, in fact I love everything vintage, audio, analog related. I have multiple vintage setups, 3 turntables, 3 cassette decks (with a Nakamichi as my main), a Pioneer reel to reel, tons of vinyl, 600 cassettes, and 41 r2r tapes. This website has been a god send for the last week and wanted to join the crew! I took the Lasonic apart this weekend to clean, deoxit (tough to get to) knobs/switches, and replace belts (though they worked the guy said he never changed them). I discovered a SBS 16.0 works perfectly for Tape A, but reading here someone mentioned SBS 8.0 for B (which isn't the case). My B had 2 smaller (4.7-ish belts) and 1 (estimating) 6 inch (2 backside and 1 (counter) front side). I'll figure it out and give her a go soon. Thanks for having me!
