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!

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.
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.
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?
