UPGRADING PREAMP CAPACITORS

[WJGJ]

GREETINGS

LARGE CAPS BECAUSE OF POOR EYESIGHT

I WOULD LIKE TO UPGRADE THE CAPACITORS IN MY PREAMP

THE CURRENT CAPACITORS ARE RATED .4 UF 250 VOLT

I CAN'T FIND A QUALITY FILM CAPACITOR WITH SUCH A RATING

SEVERAL .47 UF FILM CAPACITORS ARE AVAILABLE WITH VARIOUS VOLTAGES

WOULD IT BE ACCEPTABLE TO USE THE .47 UF IN LIEU OF THE .4 UF?

THERE ARE 4 OF THEM LOCATED NEARBY THE RCA OUTPUTS

THEY ARE THE LARGE BLUE ONES

THANKS FOR YOUR ADVICE

If that amp is working fine, then please leave it alone. If you muck about with it, more likely than not you will ruin it. You only change a cap if it fails, not because some loony audiophool said it was a good idea. Idiots, and I mean idiots, are all over the NET these days. You need to tune out the lot, and listen to voices of experience like mine. So just do yourself a favor and dump the voodoo.

YOU CAN ALSO PRESS CONTROL AND THE + KEY AT THE UPPER RIGHT OF YOUR KEYBOARD TO INCREASE THE SIZE ON YOUR SCREEN. IT WON'T AFFECT WHAT WE SEE, THOUGH.

AS TLS WROTE, THEY DON'T NEED TO BE REPLACED UNLESS DEFECTIVE- CAP REPLACEMENT OF SO-CALLED 'VINTAGE' SOLID STATE ELECTRONICS HAS BECOME A FAD THAT NEEDS TO STOP. THE ONLY REASON FOR REPLACING THEM IS DUE THEM TESTING AS 'BAD' DURING DIAGNOSTICS WHEN A PROBLEM OCCURS, OR BY FAILING COMPLETELY.
