Hi there all 100t's enthusiasts.
Here comes my contribution to this point.
Apart from being absolutely delighted with the sound and tone I get out of this little beast, I recently found that inner fan is not getting active at any time, even if the whole amp warms like if it was Hell itself. Seriously, it gets as hot as Hell and the fan doesn't start up at all :( .
I wonder if this is normal or not, I was used to playing trough a hybrid recognised brand bass head and fan was almost all day on.
Any feedback will be wellcome as I'm thinking to return it under warranty (yes, it's a brand new one :D ) for another one.

Thank you so much guys!!

Hahaha, mine neither.
I've got that manual, it comes with the amp. I was looking for the schematics as well but could not find it.
Sent to distributor under warranty.

Call, or E-mail Fender Customer Service. Give them the details, and see what they say about the cooling fan issue.

Hi all,

thanks for the hints given, finally I took it to the service center and yes, there was a problem with cooling circuitry :evil: . cant't wait to go to pick it up and let it rock for hours.
I'll post some new info when testing it in depth.

Another failing came across with this this amp :oops:
Now, the loudspeaker output Jack disconnects after no more than an hour work.
Sent back again to tech service they changed it with a new one. Old one was burnt due to the extreme hot the amp became previously. Tech service promised they had the amp running for a whole day.
When I picked it up to my last live (w/o testing anything) I noticed the tone was not that clean as before or maybe my ears were corrupted with a 350w portaflex by Ampeg. :mrgreen:
I'm certainly thinking about a full return. Not happy anymore with this amp. :|

Output jack disconnect after one hour ????
I can't understand how.

Any picture of the old one, is it a standard metal output jack ?

Yes, the sound come and go. It was a normal metal one, no pic of it because it had to be sent to Fender. The problem was that the Jack tip spring was too loose due to heating (at least that's what they said)

Normal metal jack can't have a spring loose by heat, or the tech talk about the solder on the jack ?

I see two things;
1-This amp is not a good design
or
2- The tech is not qualified.

Very often is the 2 :(

Hi Stratele.
I think both statements are true in this case. Seriously, you can't even imagine how hot the amp became while running before the fan mod.
Also the speaker plug (at the amp connection) was hot enough so as not to be touched 10min after switching it off.
