Winter upgrades - better heating unit


Guest " "

Recommended Posts

audio room is ground level with 10 inch cement walls and a poured foundation under the raised and insulated floor....so it gets cold...this should do the trick. 48 6550C power tubes. 1250 audio watts per channel. 30 amp draw at full power for each amp. 9 amps per amp at idle. VTL Wotan MB-1250 Reference amplifiers. Built in 1998. At the time, the largest production tube amplifiers.

They weight 250lbs each out of the crate. Not sure what speakers I'll use with them yet. I have power in the room, but on the wrong side....so I need to do something about that. I need to also check the tube bias settings and fuse sizes...can't assume prior owners set the bias correctly and/or didn't put pen springs in as fuses. so it will be a few weekends before I can turn them on. I have a pair of nice 40amp isolation transformers with multiple secondary taps (sort of a giant iso tap) , will need to put them in a case...so that will take time. It will def get done before winter.

These things need a moniker of their own. I'm voting for:

Big Daddy

From the Stereophile review:

Each monoblock mounts 24 power tubes on the top chassis, and a power
supply with three massive transformers and four industrial-grade
capacitors on a separate "ground-level" chassis. Imposing in their
all-black livery, they make a 19" by 19" footprint and stand almost 2'
high. And at 240 lbs each, they are a huge physical presence to
deal with, despite VTL's new peekaboo cosmetics. (While heavy, and
despite liberal use of damping material, the two-storey chassis'
torsional stiffness and resonant signature left something to be desired.
When I pointed this out to Luke, he told me he'd already specified
future construction techniques to remedy this.)


Power tubes are latest-spec Russian 6550Cs, purported to be the best of
the Svetlana litter. Inputs and drivers per side consist of a pair of
6350s flanking a single 12AT7. I'd never run across the 6350 before.
"Think of it as a double-power 12AT7," Luke told me.


The lower chassis has a standard IEC power connector and a slew of fuses
sharing the rear apron. A thick umbilical ties it to the upper deck.
The top chassis is a wonder to behold, especially at night when lit up
like a Christmas tree. The tightly packed power tubes surround the
output transformer, located dead center on top. A pair of caps stand
sentinel before it, the input and driver tubes set up before them. There
are 24 separate bias pots countersunk into the top chassis, their
separate reading points just behind the faceplate.


And yes, you must be something of a fanatic to run amplifiers that
require 48 separate biasing operations. But Statement Products are what
the Wotans are, and indeed, the fanatics who buy them are out there. In
fact, you'll read about one of them shortly.


Exploring the rear of the upper chassis, one finds a single pair of
Manley/VTL binding posts (fairly easy to work with), and an RCA
single-ended input (balanced inputs are available). There's also a
switch for tipping the amps back and forth between triode and tetrode
modes. Just think of it...600W in triode, 1250Wpc in tetrode!

Hubba, hubba. What prompted you to try these out?

I think I remember reading it cost Carver $5,000 just for the special paint job for those beasts.

Those Carver amps are the same price as an Audi R8, $115,000.00

so after burning out a few extention cords,,,,and some basic tube amp maintenance...I'm running these on some 1989 khorns which I will be upgrading to AK-4 level. I need to move in some decent power....I'm serious about burning out extention cords.

Here is a pic of an R8 that was in the VW/Audi/Porsche dealership that I'm a tech at for a recall. (incase you didn't know what an R8 looked like.)
