In Reply to: How long can electrolytic capacitors (in a tube amp) last? posted by Leslie Loh on September 28, 2004 at 03:00:30:
Not unusual given the amp is 10 yrs old. Find a local technician,
anyone with electronics bench experience can handle this. You might
have to him him hunt down capacitors that are of the same mechanical
dimensions as the old ones. Brands of electrolytics that I like
are Siemens Long Life, any NOS Sprague, Nippon Chemicon.While he's in there, might as well replace the rectifier too. Often
rectifiers and capacitors die together (sympathetically). There
are excellent and cheap rectifiers out there now. HEXFREDs will
do the job.Last but not least, you could also entertain replacing power resistors that might have drifted. i.e. plate load resistors.
