Since my 100T is in my lounge for practising I have occasionally accidentally left it on all day, during our very hot summer. When I arrive home it has been quite warm and the fan is running but there have been absolutely no problems.

note that the output power lights are all off...
UN plug it, take out all the tubes and replace in different order expect for PI tube. Also fuses may not look bad but can be. Ohm meter is the only way to tell. If that doesn't work take it back to the dealer.
All I can think of is many years ago when I first started playing we'd just grab a Fender or any other tube head and plug in a cab without worrying about ohms. Just always made sure we had a cab connected before coming off standby.
Most of those amps were pretty forgiving considering the amount of abuse we put the through. I can guarantee there were impedance mismatches going on from time to time. LOL
Thankfully things are better now and we are more tech savvy. So are the manufacturers.
You have a multimeter so you must know something about electronics. If you really want to get into it disconnect the chassis from the cab so you can work on it and check all the taps from the transformer and terminal boards, switch connections. Sounds like one of the filament voltages isn't getting to the tube section. Could also be a cold solder joint somewhere.
One important thing to remember .... There are high voltages inside any tube amp that can KILL YOU! Certain precautions must be taken before and while working on a tube amp. If you are familiar with them that's OK. If not, better to take it to a repair center.
I expected something more "simple" than i found here...

Monday I'll visit the tech
Man that's intense! It's like seeing a beautiful woman have open heart surgery.
I guess I have been the lucky one with Fender customer service. I called them about a problem removing my phase inverter tube to replace it with different one. The rep couldn't answer my question on the spot, so he got the guy who engineered the amp to email me within about an hour of the call.. Just now I got a follow up
email to check and see if my problem was resolved. Probably some of the most attentive customer service I have received from any amp company.
Sounds great through the NV215, although lacks the same visual appeal of the neo 610. The Super Bassman really does sing with the NV215. I like the fifteens with the precision but the jazz really does sing into the 610. I too am seriously considering the new Berg 115 for the 100T. I do have a GK neo 115 but while it sounds great in the lounge with the 100T it tends to bloom a bit on gigs, something which happens far less with the sealed Bergs.Tim.... I think u might have mentioned it but how does she sound thru nv215?
What number did you initially call?
Hey Peter, do you think the amp got damaged during shipping. Was all well when receiving it when you bought from Pickles?
