I must not follow what Rich has running through his mind on this one. I can't imagine a capacitor being banged every half-cycle by thousands of volts of rectified AC suddenly having a problem with an additional dozen volts! 73, Tom W8JI w8ji@contesting.com -- FAQ on WWW: http://www.contesting.com/FAQ/amps Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com |
