The veteran of the high-power tube amplifier market outputs up to 650 watts of power in tetrode mode, with 12 6550 type lamps used in each channel. Huge stabilized power supplies and an impressive case are responsible for the impressive weight of 90 kilograms per monoblock or 180 kg for a stereo system.

    The playback quality of the new VTL MB-450 has also been improved by using a shorter, faster and fully balanced negative feedback loop, with total negative feedback being zero. As a result of the use of local negative coupling, it was possible to get rid of ringing at high frequencies, in addition, the amplifier does not require the use of tuning capacitors to maintain the phase coherence of the reproduced signal.

    The VTL-MB185 Series II monoblock tube power amplifier has the same high playback quality and thoughtful balanced design as its "older brother" VTL-MB450 Series II, but it uses 6 6550C lamps and a more compact output transformer, so its power is "only" 220 watts.

    Vtl (Vacuum Tube Logic) MB-125

    The VTL MB-125 monoblock lamp power amplifier is a fairly compact monoblock lamp power amplifier. This model is designed both for installation in a stereo system and for use in a home theater system. The amplifier design uses 2 12AT7 and 4 EL34 lamps. Unlike the more "older" models, there is no automatic lamp offset current adjustment scheme – BIAS adjustments are made manually, independently for each of the lamps.
