Issue with Phono Playback.

I also suggest you use a small mirror at least 4" x 4" (I use a mirror from a cosmetic compact) to set your bias or antiskate adjustment. (Left to Right movement). Place an old thick record on the platter then the mirror. Make sure the mirror is flat and smooth. Do not use one with a frame or anthing around the edges. It will not register properly. Just Place the stylus in the center of the mirror. Zero the antiskate. If it drifts right turn the antiskate left and vice versa. Continue this until the stylus has stopped drifting in either direction.
Before you begin this use a very good protractor to setup up or cartridge and arm. Make sure your VTA is set up correctly too. I like the Dennison Soundtractor. There are many others on the market that achieve the same thing.
This will help in getting rid of some of the noises you mentioned. It will not remedy groove damage that pre-exist. But your background will be much more quieter and your antiskate will be proper. Enjoy

Gravity
A couple of years ago my 14 year old niece showed a strong interest in vinyl play back.

I donated 1962 vintage Fisher 400 receiver with head phone jack and built in phono stage.
This old receiver is what I used through out most of the 1970's, 1971 to 1979 to be exact.

Her father picked up a used Rega P3 and had a new Ortofon cartridge mounted, a pair of vintage Dynaco A40 speakers were purchased there after.

Over all the sound is surprisingly good for very little money.

A large used record store is not far away from them and everyone is happy.

Have someone set up your table if you are not comfortable doing it yourself.

I think you probably would be happier with a differant brand of electronics other then the Sony.

Ponnie, I realize that many folks think the method you described for setting AS is a good one. However, many of us have found that it always results in way too much AS.
