Shipment of a Coustic 801DB amp just came in(E-BAY).
Used, supposed to work, previous owner used it and it worked great, has been sitting at seller's house for 5 months.
She shipped regular fed-ex ground, flat-rate charge, so i dunno if insurance was included.
When it arrived today, it was in perfect shape, not a single fingerprint see-able. I tilted it on its side then started shaking it after i heard a small something shaking around from end to end inside the amp. So i open it up, and its a little metal ball, 1/4th the size of a pea, with one sorta flat side, looks like a soldering joint. So i took it out and screwed the guard back on, e-mailed her back about it but she hasn't responded, so i turn to you SWEZ, do ya think it was anything important or will the amp work?
-yes, i'm not completely stupid, i realize the only way to find out will be to hook it up, which is what i'm doing tonight, as you know from my other posts a minute ago.
-probably just the Fed-Ex guys playing soccer with a random package, and it turned out to be MINE. GRIN

It sounds like a loose solder ball alright. It could mean nothing or it could mean a solder connection has lost its' solder and performance problems could be an issue now or later.
Best to test the amp before you install same.

take it to a shop and have it bench tested. Normal ups shipping has $100 insurance, dunno about fed ex.

Did you fix that loose fuse holder joint? That's where the solder ball seems to have come from. "De-wetting" of the solder will cause this as often the board or components were not clean when installed. A little IPA (Rubbing alcohol) will cure that and maybe a dab of flux as you resolder the connection.
Use 60/40 alloy, (Tin/lead) rosin core flux is best for this kind of work.

PS How'd things turn out?
