50w-100w Valve Owners Thread

This is my 100 W stack. I got the second DB212 today. I am really surprised at how much more volume it provides. These decibels were not cheap, and I waited for the cab for 4 months... :bassist:

I think I'm a bit more biased toward the 2000s because I owned the head at one point. Does the 2000s or the V-4B break up earlier? I've only played on a 2000s and a SVT (not a V4)
The 100w V4 with 4xEL34 tubes breaks up earlier than the ~180w-200w Sunn 2000S with 4x6550 tubes.

I've played both but it's tough to choose between them. I give a slight edge to the Sunn. Both amps have different flavors of awesome. Get both if you can.
 
I've been playing about with my Jansen Bassman 50 for a few days now.

It doesn't break up. I crank it way further than I should with neighbours 60 ft away and it's shaking the whole house with lovely warm clean bass. Maybe if I take it to a gig where I can really let loose it will start to grind. It's modded a little with 7027A valves intended for a 75W amp. Might have something to do with it?

Question for ya tubeheads. When I turn the off/on to "on" ( standby is left "off") the first 12ax7 in the preamp flashes bright briefly like a lightbulb flicked on and off. The 2nd one does same but to a lesser degree. Not good?

Other thing is it has a very mild 50Hz main supply hum which is diminished to almost nothing if I ground the chassis with a finger. Does this mean I have an ungrounded chassis, potential deathtrap?
