Locating capacitors

I'm re-capping my tube amp. I'm having difficult locating some caps with a Google search. I'm not sure if they're made any more. Can anybody suggest a supplier that might have: SAMHWA axial (light blue casing)(GA) 85° C (M) 9104 350v. Thanks!
You can most likely use any electrolytic capacitor of equal or higher voltage rating - Mouser have several make sure it fits size wise and of course make sure you get the right value (uF) - also it would not hurt to use a 105'C cap they hold up longer.

Good luck

Axials are especially hard to find current replacements for. Most all the new designs are radial (with the leads coming out of the same end). Axials the leads come out of opposing ends.

I think Vishay makes a line of current axial electrolytics (you can find them at DigiKey), but the range of values and voltage ratings is limited. You also did not mention the capacitance value.

I did a Digikey search for you for "axial electrolytic capacitors", and no parts come back at 350 V. Highest is 200 V, and all those are made by Vishay, with values from 10-100 mfd.

Parts Express has some high voltage axial electrolytics under the name "Ruby Gold". They are 350-500 V parts, from about 10 mfd up to 100 mfd:


Also, are you sure this is an electrolytic cap and not a film cap?

Post the capacitance!!!
My bad! These are radial - not axial caps. The cylinder is approximately 1 3/8" long x 11/16" diameter. The capacitance is 47uf. I assume that they are electrolytic. The manufacturer is long gone. Any help is appreciated.
Mouser capacitor

Heres one that should work

Happy Soldering :-)

Make sure the amp has been off and you know the high voltage power supplies have been bled. Otherwise you might be in for the shock of your life. I also suggest you get caps rated at 105C. The Panasonic's are quite good. The bigger issue for radials in lead spacing. Make sure you get that close or the cap will not sit flush up against the circuit board.
Thanks all for pointing me in the right direction. Hifigeek1, I never would have thought about the lead spacing. This project might take awhile. Let's see if I can put back in the same amount of parts that came out. LOL.
At that capacitance you might also be able to find a polypropylene film type. It will be a larger and more expensive, but sonically a vast improvement. And those will be radial so they may not fit as well.
I'm getting closer to ordering. Some capacitors have specs that say that the 'load life' is 5000 hours. Others do not even mention load life. Which to choose?

I would choose the cap based on operating temp (105C preferred over 85 C), then the lowest ESR (equivalent series resistance), then finally ripple current (highest best). Load life is generaly the life of the capacitor operated at a given set of conditions specified by the manufacturer (like maximum temp of 105C and max ripple current) before it begins exceeding its specs (say for example, leakage current, which may steadily increase as the cap gets older). A 2000 Hr rating will not be as good as a 5000 hr rating, for example.

More advice, please. I am unable to locate a replacement for a Nichicon 4700uf, 100v, radial leads, 30mm diameter x 45mm height, 85 centigrade. The diameter is the problem. The newer caps are 35mm in diameter. Since my amp's circuit board has 4 packed together, there's no room for another 5mm each. I've checked Digikey, Mouser & Newark. Can a snap-in be converted somehow? Any suggestions?
It doesn't need to be a Nichicon. There are plenty of good quality cap manufacturers out there. Why don't you call the manufacturer of the tube amp you own and see how much they want for the part.
