    AR 18BX speakers: Upgrade or a good compliment?

    Hello. Newbie here. I'm a bit of a novice at vintage speakers as far as technical knowledge but know enough to prefer vintage over anything after 1985. My setup is nothing to brag about. Most of my experience is in collecting vinyl albums since I was 10. Between myself and my oldest...

    AR-XA motor question

    Hello all, Old member here who just did a nice tune-up on my AR-XA. Every few years I clean it up... I wanted to oil the motor with sewing machine oil. And to my surprise, I had forgotten what motor was there under the plinth. And guess what? I don't know what it is. Does anybody know what...

    Hi everybody after roughly 25 years of music, three relocations and two quite active kids, I had these speakers serviced. The technician replaced the foam suspensions and serviced the tweeter domes which had been dented. I bought these speakers back in 1991 and they have been connected to my...

    AR XA Problems - Platter too slow

    So one day not long ago, I was listening to a record and all of sudden the platter slowed way down. Since then I've changed the belt twice, applied talc, re-oiled everything, and tried different outlets, but I still can't get the platter up to playing speed. On top of that, when I drop the...

    AR XA turntable score?

    I found a AR XA turntable sitting in a shop. The owner said it's been sitting for a while and that he's asking 75 for it. The veneer on the plinth is peeling a tiny bit. Not enough to detract from the table. It turns on and the platter spins... is this table a good buy? I was going to see if he...

    AR-XA with cryptic mod--what is it?

    Scored this AR-XA for a steal at $60, but it's got this machined part on its surface with a spring on it. What could it be? See it on the bottom right there? The spring unscrews and detaches, but the bottom piece appears to be fixed to the top plate. It looks to me like the pulley for a...

    AR2 woofer stopped working

    Hey AK, Picked up a pair of AR2s a few months ago and have been loving them, but now one of them only operates the dual mids (aka tweeter section). I don't think these have ever been opened up, but can't be sure. What I do know is the crossover knob feels dry and slightly squeaks (like nails on...
