Here's my 66 Vibrolux Reverb I shipped and sold in the US.
You're correct, it's the Deluxe Reverbs big brother...not too heavy, about 27 kilos, perfect gigging amp.
It is definitely not an apartment amp, only starts sounding good with volume on 4 or 5...by then the neighbours are standing outside your window with baseball bats. ?....and you dare not attach an attenuator to a vintage Vibrolux or Deluxe Reverb. ?
Don't be fooled by attenuators, IMO you won't get poweramp distortion in an apartment unless your attenuator is turned down to 2 or 3, and by that time your amps "true" tone potential is destroyed, and it's still too loud.
I use a Weber Mini Micro Mass attenuator in my apartment, the one that has two attenuation knobs, one for lows and low mids, and one for highs...and even with my 15watt amp, with the attenuator on 4, I can't get my Master Volume above 1,5...so Im not getting any poweramp distortion.
