Speed problem on Thomas Pacconi Turntable

My Grandparents have a Thomas Pacconi 7470 model and can't find the manual. 78 is the only speed that will play right. It will turn with the 33 and 45 but won't play at the correct speed. I don't know where to start and can't find the manual online. Any suggestions?

I have Thomas Pacconi 3-speed phonograph model TPC-7475 and wanted to attach external bookshelf speakers. Is there any way to hook speakers up to the line out jacks?


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.

Thomas Pacconi Model TPC-MSE-800 turntable runs slugglish. 78 runs fine but 45 or 33 runs slow. I removed belt cleaned it and platter. I put a drop on oil still same problem. Do I need a new belt? This is...


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!

WHEN I PLAY A 331/2 RPM LP IT SOUNDS A LITTLE


The needle itself will not induce drag on the record. Even worn needles play no role in the problem you describe. The belt, provided it has suffcient tension to turn the platter, is doing it's job. The most likely source of malfunction is the motor itself. Try sliding the speed switch back and forth while the turntable is turning. If you see no difference in the speed between the 33 1/3 rpm setting and the 45 rpm setting, you have most likely eliminated all sources of the malfunction other than the motor. They are very prone to failure. If a replacement can be found, the job of installing it is not particularly difficult but indeed should be left to someone skilled at soldering electronic parts.

We have a Thomas Pacconi record player and the band underneither the turntable has stretched out. The band is black, about 1/4" wide, and round. Can you help us.


TBirdMM, thanks for the advice. I was turning that dial this morning tweaking the rpms and it worked! Strangely enough I actually broke the white dial off, but when I spun a 33 on the 78 setting it played right on! Thanks!

Does anyone know why that dial only effects the 78rpm setting, and if there is a dial for the 33 rpm setting?

Thomas Pacconi turntable turns too slow


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.
