20 Most Recent Seth Thomas Pacconi Turntable Questions & Answers

My older Thomas Pacconi turntable was also turning too slowly. Rather than replacing the belt or needle, I tried using an eye glass repair screwdriver to alter the trimmers inside the motor. But the changes didn't take. Then I tried trimming the power to the motor using the larger trimpot next to the motor with the motor itself set to the 78 rpm setting. But the adjustments to the trimmer didn't get the platter to spin slow enough - it wouldn't play an LP. To get the speed down further I replaced the 1K trimmer with a 10K trimmer I picked up for a buck at Radio Shack and successfully adjusted the turntable down to down to 33 1/3 rpm usage. All that was needed was a soldering iron and a 10K trimpot to get the job done.

did you figure it out?

You need to buy the Jack's male plugs, Wal-Mart has them if memory serves, and splice your speaker wires onto them, preferably with a soldering gun and heat shrink insulation.

Lift the record platter up, it is just sitting on there and then you can replace the belt.

Hello there, there are so many things I could be wrong so to prevent rambling I will make a simple suggestion, check the needle. (Replace) if this does not work, just try reposting your question with the model of your item and any noises you may have experience before the device failed smells or sounds. Also if you have done anything to attempt to repair the unit. Are the speakers a part of the unit or are they separate. Good luck! Thanks! Questions? Just ask! Me.Mike

could you include a picture of the under side of the turn table where the belt is fitted?

Since you have no sound even on radio, it's not going to be a bad tt motor. There is no fuse except for a thermal fuse inside power transformer. I would start with a continuity check accross both of the blades on the plug. If it's open, you prob have a bad power transformer.

Pjam,
Had the same problem & checked around on the net. Several people tried replacing the belt, but it had no effect. Spoke w/ several repair shops around the country and they concur with what I'd read on the net - bad motors. 3 or 4 repair/supply shops told me getting a motor would be impossible. Since I only listen to 33-1/3 LP's, I messed around w/ it a little and found a solution. Take the turntable out of the unit & you will find a small circuit board attached to the bottom. On that board is a small square blue fixture w/ a white circular "dial" in the middle (has grooves to accept a small straight blade or a phillips screw driver). This controls the voltage to the motor, which in turn controls the motor RPM's. If you set the selector switch to 78, you can experiment /w turning that white circular "dial" to slow the motor down. It isn't very hard to get the speed set properly. The down side is that you will only be able to play 33-1/3 LP's, but they are probably the most common anyways. I assume you could do the same to set the speed for a 45, rather than a 33-1/3. Down side is that you will only be able to play 1 size LP on the 78 speed setting, but it's an easy adjustment that can keep an otherwise in-op turntable functioning. Good luck!

Try changing the needle which runs on the record this is to do with clarity , makes a big difference and you get many types of needles

All you need do is look at the cartridge it fits in. There should be a maker name and model number on it. Put that into Google and you should find it - plus the stylus.
