Increasing the voltage rating is fine as long as it physically fits in your unit. As for using a 20uf in place of a 10uf, you would need to check based on the application.

The JJ cap requires a clear opening of at least 1.3" diameter. If your original can cap is smaller than that, you either punch out the hole to a larger diameter, or DO NOT USE the JJ cap.

I do not have experience with the Dynco PAS 2 preamp, but looking at the schematic (which does not show the Filter capacitor values), I would use the 40mfd tap as the first stage filter. As on old Fender guitar amps, filtering originally was done with a 20-20-20-20 Can Cap, but later upgraded to a 40-20-20-20, with the 40mfd being the first stage filtering. Gives you better startup (inrush) spike protection. Hope this helps. Dave

The two bottom contacts are 0.535" apart. The distance from the bottom lug to the second row of lugs is 0.535" and the distance from the middle lugs to the top lugs is 0.45". Keep in mind, these dimensions are approximate and the riveted terminals means each will be slightly different.

They work fine but required resizing the hole spacing from the old Mallorys.Also they measure 47/22/22/22

Excellent product, perfect for amp builders like myself! Small footprint, low ESR. No, don't try to replace your can cap in that '67 Prince with this unless you don't mind breaking the vintage code of conduct, but if you design and build cool, great sounding amps then check this one out.

I've used JJ can caps to save expense in projects in the past, this last one was doing an EICO ST70. If I had to do it again, I'd chose to avoid the JJ 40/20/20/20. Its leads are so broadly spaced it made it a real PITA to fit this can. Really braindead design, could've been less of a cluster if they'd used their head when it came to the lead spacing.

These capacitors are a great deal. They are inexpensive, take up little room, handle plenty of voltage and are well made. The uf values are good for most of my amp projects, too. Definitely five star value.

This is a great cap for small tube amps. The 500V rating gives plenty of headroom for the startup surge of amps that operate in the 300-350V B+ range. A bit larger in diameter than most multi-cans, but can squeeze into most rebuilds with the 1.5" clamp and sometimes drilling one extra #6 or M3 screw hole to mount the clamp. I like to use this cap on EL84 builds. It takes up less than half of the flat space and simplifies wiring compared to individual caps that I used to use, and has yet to disappoint. Also note the 160mA and 80mA i(ac) ratings per section, which should be more than enough for anything using EL84 or 6V6. As a bonus, the price is tough to beat for the functionality. I recommend you give one a try if you are (re)building a <12 Watt amp.

Recently bought a cappacitor and retaining ring. Price was reasonable, shipping was fast, item was as advertized. Fixed a HP 400c meter and it now works very well. Thank you for stocking parts for vintage equiptment that are hard to find. I was very happy with my purchase and will look forward to future dealings with Antique Electronic Supply.

Haven't had one fail yet. The 40/20/20/20 is a great size for smaller amps, and construction seems beefy and resilient. Love this cap.
