Old School Maintenance

Wyloch · 21st June 2005, 11:20 PM

I have a Carver m-500t amp that is coming up on its twentieth birthday pretty soon. I've read that older amps tend to have their capacitors go bad, and the result is that the sound quality degrades (the exact symptoms vary depending on the sources I've read). Unfortunately, I only came into ownership of the unit last year, so I can't compare it to anything.

Do I need to worry about this? And if I do, anyone recommend what brand? Money is no object - I want the best audio-grade caps available to mankind.

Hi Wyloch,

There is no shortage of gentle folk out there willing to supply you with 'the best capacitors known to mankind' lovingly nurtured in the making by vestal virgins in full flight pagan ritual wrapping ceremony, not for viewing or beyond the understanding of we mere......

We noted on another thread, Chemicon - a manufacturer of fine electro's in your part of the planet. Might be a good place to start.

Hi Wyloch,
Replace overheated resistors in the power supply circuit and check the DC voltages. Replace any caps that were beside hot resistors.

Nice looking amplifier. Puts out lot's of power.
