Look down the page to my posting of May 14, 2013. It has a list of
values and part numbers for VERY LOW ESR electrolytic replacement
caps that have a higher Temperate Tolerance than the originals, and a
couple of value changes for lower 'ripple' out of the 20V voltage
doubler chip circuit,(helps with the display flickering while warming
up) and better +5v working voltage for safety.
I also outline 2 tips for easy removing and replacing the caps,
including a simple trick to clean out the PC holes for inserting the
new caps. I have done this on 3 565's without problems.
FWIW The battery can also be obtained from Mouser, and also a higher
capacity (longer lasting) pin-compatible version as well.
