Hey Tim, what do you know about crackly old amps? 1980's peavey sounds
like it is always playing through a buzz box...
Probably needs the pots cleaned and connections checked. It's kind of
hard to tear up an old peavey. i won't say their bullet proof, but
close to it. you might check the plug-in and see if it's properly
grounded to the outlet. does it have a reverse polarity switch?
probably not. It sounds to me like itls in the connections and
ground.
also you could have a torn speaker cone. Interesting that before
Richie Blackmore started playing with Deep Purple, he couldn't afford
a "Good amp" with effects, so he took a razor blade and cut slices in
the speaker so he could get that "fuzz" tone.
Evidently it worked for him.

I cleaned a
bunch of the connections and can get a relatively clean sound in solo,
but as soon as I hit a chord, it really roughs up. Any help would be
apprecialted.- Hide quoted text -

Turn down the gain? I'm sure you also tried the low side imput . It's
possible that your pickup[s] are too high/close to the strings as
well, and getting a harsh or too tight of an electrical field. (just
a thought)

Well, not looking at the amp I can't say much. but...

Plug it in, and flip the polarity switch, and see if the hum is
reduced. If not, then scratch that idea.

your pickups shouldn't have anything to do with what you're
describing, Scott. the pots (volume, tone, effects etc.) should be
accessable and there would or I'll say " should" be like a pin hole
or some say a vent hole on them, and usually a slight squirt of
siliconized electric contact cleaner in them should take care of
cleaning and lubricating them.

Outside of any of that, I'[m pretty well clueles.

you might check the guys at alt.guitar, alt.guitar.amps or even
alt.audio.pro

I'm sure there's those a lot better than I that could help.

Does the speaker have foam suspension? After some years that foam will
break down. I had some 15 year old speakers repaired and they sounded as
good as new.


Doubtful that a guitar amp speaker would have foam suspension, particularly
one from the 80's. Even new ones are hard to the rim.

But, that doesn't mean the paper hasn't been torn or otherwise deteriorated
from it's mounting.

Could be a bad voice coil.

That would be my guess, and for good reason. He says that if he plays single
notes lightly, it's fine, but when he plays loud chords, it sounds awful. The
voice coil probably has a burn in a spot that is beyond the amount of movement
caused by a light single note, but gets reached when you play louder and the
coil excursion increases.

Then again, if the amp is from the 1980's the speakers are deteriorated
regardless of whether they buzz or not.

Sounds reasonable. how do I identify the voice coil on the board, can
I test without a schematic?

Take the grill off the front of the speaker, put your hands on either
side of the speaker and gently press the speaker cone in a couple of
times. You will proably hear a scratching noise and the movement will
feel rough. That means the voice coil is bad. If you don't get the
scratching noise and sandpaper feel, then it's good and probably the
cone is bad.

Voice coil is part of the speaker. It's the cylinder at the narrow end.

If you have access to somebody else's speaker cabinet, you could plug your amp
into their speaker and confirm you have a bad speaker.- Hide quoted text -

Cleaned up the parts and connections I could and started playing with
it. Seems to be getting better, I am thinking more about it being
speaker related. But with more and more play, it seems to be getting
somewhat better, could old speakers just be stuck and slowly work
themselves in again?

Not really. but paper cones can get brittle. I suppose that a bit of
playing can soften up the adhesives a bit, but not really sure. Or
maybe you're getting used to it........

Oh yeah...

But sometimes a clean tone (with a tad of reverb) is kind of neat too.
