BAT VK 55 SE

Ok. Those output tubes really have my interest. I'm not a tube guy. MIG Jet fighter tubes? That can withstand EMP from a nuclear blast?  This is stuff of legend. 

tooblue, The dealer that I am possibly getting the BAT from is also a VTL dealer.  I used to work for the dealer so I get 25 percent off retail. Wonder I should go VTL ST 150 instead of the BAT? 

I took a regular VK 55 home to audition. My speakers are 4 ohm so I hooked them up to the 3 to 4 ohm taps on the BAT. There was a channel imbalance, one channel was weaker than the other. I hooked up the 4 to 6 ohm taps and the channel imbalance got better. Must be something wrong with the amp, bad caps or transformer. The tubes are new. I'm going to try the SE version and see if it works.
