[Jukebox-list] Tonearm "problems"

[Ron Rich]

Rick, and all,
  Most of the time when I have found a mech that "skates", upon needle setdown, especially when it's worse on the "B" side of a record, the cam shaft shims are incorrect. The book says to shim  from .003 to .01--I favor the lower side as much as possible. If you are having this problem, watch the cam shaft as the needle sets down. It should not "jump sideways" ( or "jerk" during rotation).
  If you hear needle set down thru the speakers, it indicates that the mute switch (or, in LPC's-up, the relay hold switch) is incorectly adjusted.
  Of course, this assumes that all of the other things, such as balance, pressure, and cradle adjustments (including "trip switch balance spring"), are correct--first.  Ron Rich

  Hi JC,
I have had several 222's and they all had the original red tone arm/ cartridge and all of them (mechs rebuilt) set down too fast/ hard and even skated in a few grooves to boot. The tracking pressure was correct on them all. I did have to readjust the reset levers on them as this was causing the skating, but they still were too rough on the set down and none of them ever sounded good. My 1958 Wurlitzer 2200 sounds a lot better (with the stereo arm and cart conversion) and is very gentle on the record loading. As much as I love the 222, I don't think I'd ever own another. If I were to get another Seeburg, it would have to be a mono one, not anther early stereo version as they sound too bad (I'm not going to put up ugly external spkrs just to try and get better sound). I think the sound system in those early stereo units was poorly designed. They could of at least added tweeters so you could get decent sound from the juke without the extra expense and space needed for
 externals. Those "full range" spkrs were not very full range at all, even after reconing them (it did help, but not much). Rick.

I'll check those things. Hopefully it's one of them. It's a good idea to 
check the needle pressure anyway to make sure it's not wrecking my records. At 
least it hasn't wrecked a needle yet but it can't be good for the lead in 
groove of the record. A few tick a couple times on the lead in groove that didn't 
before they were put in the 222. Also it looks like it sets too close to the 
edge of the record and jumps into the lead in groove.Thus the thump noise I 
hear. Looks like my next project is to check the tone arm adjustments on my 
222. If looks like I need the fluid replaced for sure I'll contact you off 
list.
