Twin Reverb....reverb tube hot?
Hey guys, since my Evans amp is sick (thread below) and i have a gig tomorrow night i pulled out my trusty kick azz twin reverb (blackfaced bias supply and phase inverter and tweeded preamps (both channels have reverb). This amp absolutely smokes!  
 
Anyway, i had played it a while and was fooling around in the back and noticed the reverb tube was hot, really hot.....is that normal? I have never noticed it before but never actually felt the reverb tube after playing it either. Everything works just fine, was just wondering if those tubes are s'posed to get hot like that or do i have a reverb tranny about to go or something?  
 
As always, much appreciated on any info

That 12AT7 will have 400v+ on it & yes they get quite a bit hotter than the other preamp tubes.

Thanks Mark,  
 
I've had a rash of circuit failures over the last 2 months and prolly just paranoid waiting for the next shoe to drop :)  
 
Thanks again
