since you have had one of the original capacitors fail it would be a good idea to put all new ones in, as well as the ones on the board.

use 6 of these per amp, 4 for power supply and 2 for the speaker bank, the amount of capacitance will be very close to the original configuration.
these are photo capacitors with the same voltage as the Rubicon's that were stock.

I have used new computer grade capacitors in a few of the rebuilds I did,
but personally I think the new Photo Flash are the way to go.
