Bit of "fuzz-tail" along with the sound

[Loukas]

Hell.
Recently i got my silver top .
Everything works ok except when i play , the sound from the cabinet comes with short of a bit "fuzzy-tail" just like you hear an overdrive on the guitar but in a very small amount .
I am sure there is not a problem with the harp output neither with the preamp because i have shawp them and test them with the other suitcase Mark II ( via outputs) and both work clear and fine .
So i have isolate the problem between the amp or the speakers .
Any idea what is going on?
Thanks

Do you hear the same fuzz when you listen with Headphones?

If yes, then could be amp problem.  If no, could be speaker problem.  These cabinets also have some kind of cross-over component hooked up to the speakers, but haven't seen a bad one yet.  You'll see what I'm talking about if you remove the panels.

Thanks Ben ,
This old cabinet hasn't got a headphone jack .It must be an amp distortion problem ...I connect another speaker via  amp from the  inside jack it has  and it came out  kind of distorded again.
I will give it to a friend for further look.

Oh right, force of habit - Yeah the cabinet only has External Speaker and Piano Input jacks -

If it's distorted through an External Speaker then I'm guessing it's probably an amp problem.  And probably the power amp, not preamp is my guess.  Your piano looks so original it may have never been rebuilt or looked at
