Product Reviews
My second or third choice now. 3rd or 4th if you include restuffing old cans. The low rated temperature is not a very good selling point when I can buy caps from a USA custom winder for competitive prices that are rated for 105 degrees C. These CE caps are usually in stock. The other caps have a lead time of 2-6 weeks. A rating of 55 degrees C is not very good. I think that is only 131 degrees F. I would assume these are probably good for closer 80C but no one has done any real testing either. Do I want to risk a pristine 1968 Ampeg Gemini II to this cap failing? No, I do not. I'd rather buy this cap and custom order a 105 degree cap. I can get the amp running fast and then put in the better cap later on so the amp is more reliable. Mallory was using potting compounds made from Gilsonite or a natural petroleum asphalt, otherwise known as tar or pitch, and it degrades in high temps. Modern caps are using a non-acidic electrical grade silicon potting. I don't know what the electrolyte film is in these. It has to be better than 1950s aluminum & chemical electrolyte on Mylar or paper. 3M makes a nice inorganic "paper" for capacitors. It's inorganic so it's not really paper.
Fits perfectly in Ampeg B15N mounting bracket. Truly happy to have found that part. Thanks for keeping our oldies running!
I previously gave this capacitor a 1 star review. I can't edit that old review so I'm writing a new one instead. I apologize to AES, the cap I received was not defective. The problem I had with my Audio Research D-76 amp was a bad zener diode causing this AES cap to arc and burn up a resistor. The original multi-section cap (475vdc) did not have any issues with the bad zener, but this cap (525vdc) could not handle it. Once I figured it out, the AES cap has performed well. So, while this isn't as robust as the original cap, it does work well.
If you are going to recap any Audio Research series 50-75-76 this is the hardest cap to find at a reasonable price. The cap is a "bolt in" replacement and works very well. Forming was not required, but I did soak it for about one hour at 500VDC.
I bought this cap.to replace for C27(4x40μF/475V) of my AudioResearch D-51 Tube Amplifier.This capacitor fits fine to the D-51 main PC board and work well.
I purchased two of these caps to replace the ones in my browning mark 3s and I have never had a problem i have used the radio every day for the past three months will be buying more in the future
I bought this as a preemptive replacement for my Audio Research D-76 that uses a 40uF x 4 @ 475VDC pcb mounted can capacitor originally made by Cornell Dubilier that's now 42 years old. My tech, who's a 30 year veteran working with tube gear, did the installation. While applying voltage after installation, this new CE cap started arcing and burning up a 2 watt resistor. Tried it again after having to replace the resistor and it did the same thing. My original capacitor went back in and that works fine. So I have a defective CE cap and contact Antique Electronic Supply to get a replacement. The replacement did the same thing, it started arcing and burning up that resistor. I have to say that each section of this CE cap tested fine for capacitance. But I went through 2 of these and they both failed immediately. Perhaps there is not enough insulation between the plates internally(?). This CE cap is rated 50 volts higher than my original cap too. I hope Antique Electronic Supply figures out what went wrong during the initial production of this cap and can correct it in a future production run. Audio Research charges $250 for their replacement of my quad cap so that's out of the question for me. I'd rather not have to come up with a non drop-in replacement.
