amp woes

[de-vaughaun]

hey, i have an early 90's yamaha amp. 75 watts with 1 speaker i think its a 12" but it could be a 15". (i can get more specifics later if needed) either way. no matter what guitar is plugged in, what setting its on etc etc. there is always this rediculously annoying hum. it seems to get quieter as longer it is on and if i mess around with pickups and volume on my guitar i can lower it a bit too. but is there a way of getting rid of this? there is 2 channels on the amp (1 clean, 1 slighty distorted) but other then basically no effects on it. thanks in advance!

Sounds like your amp could use some new capacitors replaced in the power supply...These caps should be replaced about every 10 years and they filter out noise and hum from your ac current coming into your amp...These normally are the largest caps in your amp and they look like round metal cans..

It's a great place to start and your amp is in need of the caps anyway...If you're good with a soldering iron,all you need to do is write down the mfd and voltage values of each cap...Watch the polarity and solder in the replacements...

www.mouser.com or www.hoffmanamps has the most common values...I Like the Sprague TVA Atom capacitors...
