deHavilland Electric Amp Ultraverve 3 Remote Fresh tubes

UltraVerve 3 Remote Preamplifier. 
Tubes were just replaced this spring, but it turns out they really didn't need to be, still lots of life left on them. I'm including the original tube set as well as the replacement set. 
I am the original owner and bought the pre-amp in 2014. 

This is one of my all time favorite pre-amps but I no longer need it since I simplified my system by changing to an integrated amp. It does come with the relay actuated analog computer controlled 32 step stepped attenuator
