No Signal with ART Tube MP

Hello,
Brand new member here.

I have an ART Tube MP Project Series, and had loved the sound for many years with my bass, provided that you don't put everything to 100%.

Recently, it has just stopped working.
The lights come on, and I have looked inside and the tube looks clear still.
I have tried multiple cables, basses, and even power supplies.

No sound comes out at all. No signal seems to be going in.
(The dB meter does not register anything.)

Anyone here have any ideas on what could be wrong?
Was going to see if I could get it bench tested this afternoon.
 
tube would be the first guess...or the plug/jacks.
For $35 or so...you got a lot of use out of it.

I have a $2000 preamp that has scratchy pots and decals that will rub off....so even if you bought a new/used ART MP cant say it was a bad deal.

add...Ive got the ART TPSII which is excellent, it holds up so well to expensive stuff, its hard to comprehend why?
The brain isn't conditioned to think a piece like this should sound as good, so it seems in my "brain" assumption that more $$$$$ = Better gets confused when that formula is found to be false. SOS magazine found the ART MPA to beat out many expensive preamps in a pretty large scale, professional blind-shootout.
