Well I sat down to play the 500 Today, and the
fuzzy sound was back! So I tore the amplifier apart
and sprayed every molex connector I could find in it,
male and female side. Shoved 'em in and out a whole
bunch of times as per advice from forum friends. Put it back together, Amp's working fine. Next time it goes toes up though, it's going straight to Peavey. Tennessee Lee

Update! I finalley had some time to get back to this amp being that my wife has been sick. After listening to it intently, I have determined that the fuzziness was most noticeable when playing the lower strings on the guitar,(letting them ring). I plugged a Peavey 15" scorpion into the 500 and The amp sounds fine with that speaker. However it must be an 8 ohm as there was a small power drop. Can I use this speaker for a while without damaging the amp, while I try to get the 500 speaker repaired. Could something be loose in the speaker that could I could fix. Or could something have fallen in the speaker? I didn't notice this problem before the amp was repaired. Any information would be helpful. Tennessee Lee

I suspect that the foam has degraded and is gumming things up in the voice coil gap. Take the speaker out, unbolt the speaker magnet, pull it STRAIGHT OUT (don't allow the coil to scrape the magnet, the thin wires can get nicked) and clean out the gap.
It will do just fine with the 8 Ohm speaker, but put out less power.

The Scorpion could just be less sensitive/efficient than the speaker in it.
To determine the impedance of each speaker, measure the DC resistance. If it's about 5.x ohms, the speaker is 8 ohm. If it's less than 4, say half of 5.x, then it's a 4 ohm speaker.
I can't speak to that amp, but most solid state amps will run fine with a higher impedance speaker. |

| I have never thought to post information about a lubricant/cleaner that our factory techs use on every product that we service here at Peavey Electronics. Our techs use an aerosol called Peavey Funk Out that can be purchased either direct from Peavey USA or through an authorized Peavey dealer in your area. This cleaner/lubricant really works well. I spray all of my switching type jacks(power amp in, effects return, etc.)jacks with Funk Out occasionally to ensure that the jacks will function properly. Check it out! |
