"must have" accessories for TT and LP?

Good responses. I would add a bubble level, small mirror strobe disc and light. Test records; there are many fine ones. I like the Radio Shack/Stereo Review model for the test tones. A sound level meter helps also as well as a nice stylus force gauge.

All of the above are very good. Agree totally. Enjoy!

A one inch wide paint brush for dusting.
Gruv Glide.

I agree too, except for the clamp. Depends on the turntable. Many will do better with a Ringmat than a clamp (including some that CAME with a clamp). Good luck and have fun.

I sneaked a peak at Jeff's, but here is the complete list of what I consider essential.

Protractor
Magnifying glass
Tweezers
A couple of small screwdrivers (for those small screws)
Allen wrenches for some tables
Record Cleaner
Stylus Gauge
Test Record like HiFi News (the Cardas record is nice supplement)
Record Brush
Stylus brush (comes with the cartridge)
Level (Clearaudio makes a nice, overpriced one)
Inner and outer record sleeves
A cold drink
