Replacement Capacitors

I am looking at replacing the 3 capacitors in my Dual CS 1268 turntable. I was hoping someone can point me to the specific ones I should buy as I am not familiar with buying capacitors. I have soldered some kits before so I am comfortable enough doing this. One other question I have is do I have to discharge the capacitors before unsoldering or can I just unplug the table and unsolder them? Thanks!


For each I found the below.

C1 = 399-R4Y5I21005000K-ND
C2 = 732-5889-ND
C3 = 732-5731-ND

Please review these for your needs!

Hello an0thernumber,

Excellent! Isn’t it wonderful that you can walk into nearly every department store today and purchase music on vinyl. I haven’t seen this since I was a young child - even then, music was moving to cassette tape.

I’d like to add a few comments about the capacitors. Your Dual turntable is a line powered device. This requires capacitors with additional safety ratings. I’m sure you noticed the prominent “X” and “Y” on the capacitor body:

  • Type X capacitors are placed directly across the 120 or 240 VAC line. This is no trivial application as the capacitor is subject to a good measure of abuse as line transients over 1000 Volts may be present.

  • Type Y capacitors are typically used to connect line to ground.

I once had a laptop computer that wasn’t built correctly. It was a hazard when the battery was being charged. When I was barefoot, I could feel the tingle in my palms when I rested on the metal laptop case.

The question for you dear reader, is to identify the defective capacitor in my old laptop computer. Was it type X or Y? Here is a short video to better explain the importance of X and Y safety capacitors.

Thank you to @Nathan_2268 for providing the appropriate part numbers.

Happy listening,

While it never hurts to use a clip lead across it to to discharge a capacitor before removal, in this case it is not necessary for two reasons.

  • Capacitance value < 1uF
  • Connected to AC not DC (with AC it charges/discharges continuously leading to 0 volts at power off)

Thanks you everyone! I ordered the capacitors last night! If the physical size is different that is fine since they are rated as the same part correct?


Modern technology makes all newer capacitors smaller than their old counterparts.

While is doesn’t apply here, a nice trick when restoring antique electronics with can capacitors is to remove the guts and install the new capacitor inside the old can to preserve the original look.

Hello Paul,

This works for the old radios:

I once worked for a man who would rebuild the old twist-lock capacitors.
