Re: How long can electrolytic capacitors (in a tube amp) last?

hi jim, electron, jim etc

thanks for the valuable input.

i called leonard of ARC just now and he too advised that i should change the e-caps after 10 years. he further told me that of late there has been a lot of older ARC power amps returned to the factory for repair/replacement due to bad e-caps. so that is really reassuring.

i can only get BHC Aerovox e-caps in my country. leonard said BHC is good cap. the only issue is the BHC is 1,000uF whereas my existing Philips is 800uF. the operating voltage is the same, 450V. i guess that's not a big problem.

ARC's price is really shocking and way out of my budget! Anyway, as jim wisely put it - i may even get a sonic improvement using newer e-caps!
