I write to let everyone know the AR-XA I have been discussing and obsessing over went to work this evening playing music!
I actually got one LP side to play last night, but when I tried another side, the left channel signal dropped out and, when I moved my hands around the tonearm and cartridge, a pronounced hum came on, louder as I moved my hand closer to the arm. Despair.
I believe on this turntable, the ground is in the left channel and because it was the left channel that dropped out, I figured to try changing that connection. I sanded the inside of the sleeve on the left channel RCA plug and used some needle-nosed pliers to slightly crimp them inward so they'd make better contact with the socket on the receiver. No hum, no signal dropout, just beautiful music! I played two LP sides with no problems.
I want to thank all those inmates who so generously offered help, sympathy and advice. I may be back at some point with more questions or problems, but for now, everything is going well. This thing is filthy and will need a lot more cleaning, but for now--all is well.
Thanks again

Not sure why ghost had a problem with DeoxIT?
But Caig makes different products for different purposes. Cleaning contacts is not the same as preserving them once cleaned. D-series sounds like what is needed.
I've had success with their products for years.

Deoxit D5 only, but I do have Deoxit red and gold lying around.
I remember comments on Kontak but never tried it.
I lived close to the Caig facility and after a dealer recommended it bought a bottle of their red contact cleaner. Such a small amount is needed I still have some in the bottle decades later.
Now I also have DeoxIT D5 and Gold.

Check the contacts between the headshell and the tonearm.
I'd advise the use of metal polish and a thorough clean with 90% isopropyl if they need cleaned.
I've had issues with old Duals, the contacts between the cartridge sled and tone arm get dirty, same with the cartridge clips. The TT will play fine for an evening and then drop one channel the next day.
DeOxit seems to make things worse.
The blissful counterstroke-a considerable new message.
Good to have this advice. Thanks a lot, ghost, for your steady help and advice, not only to me in this instance, but to others for your interest and enthusiasm for vinyl and knowledge you are willing to share. Cool.
experience with a car battery during Christmas in Alaska. When I turned the key on my Ranger pickup below 10 degrees F, all I got was dim dash lights and no start up. Desperate, I got some sandpaper and totally cleaned the battery and cable terminals. Bam! It started right up. Very cold weather really shows up any weak area. I used to periodically clean all RCA connections to eliminate green corrosion and possible distortion, but I have been lazy these days.
Thanks, alaskashiatt, for you help in sleuthing out problems with this turntable. I was very close to putting it up for sale on craigslist as "for parts-not working". Im sure glad I didn't. Just a little more effort and it's working fine. It's people like you that make this forum so useful and enjoyable--a font of information and experience shared.
After your story about your car battery and the effect of cold, I have to tell you about my car experience.
I went to grad school at the University of Wisconsin at Madison, 1971-72. The first winter we were in Madison was the coldest winter they had in a decade. I remember one day, the windchill was 65 below. Daily highs were around -4, nights -25.
We lived in a garden apartment with no garage, so the car sat outside in a parking lot. We had to bring the battery into the house every evening to keep it from freezing and to have good charge to start the car. Also, the passenger door lock freeze. We could open the door, but it would not latch when closed, so we drove around with the passenger having to hold the door closed. Fun times!
I had a '62 VW bug with a 6 volt battery when I first came to Alaska in the Air Force. I had to take the battery into the house at night and into the squadron during work hours. I also had an oil pan heater too. When I worked on the car at home, I wore tons of clothing and bunny boots outside. I had to take breaks and go back into the house to warm up. I would place my gloves on our space heater to warm up also. I lived in a quonset hut for 7 years. Gosh, I sure miss the good 'ol days.
