Bill Woods almost always wins the biggest, heaviest thing brought the longest distance award, and this year was no different.
Bill is one of the finest horn and speaker designers in the world, currently working for Yorkville Sound in Canada. In the
past, he built a number of bass horns inspired by RCA's Twin Power speaker, which was created for the 1939 NY World's Fair.
This reentrant horn was cast in multiple fiberglass sections and mounted in a plywood enclosure. Bill brought one of the last
known examples, which we somehow managed to haul up to the Mill's 3rd floor (this is a VERY heavy speaker.) Using a single
Altec 416 15" driver, it became the basis of a fantastic 3 way mono setup, with a JBL potato masher horn and JBL D 175
compression driver on the high end, and Bill's new cast aluminum conical horn with a RCA 1428B for the all important midrange.
Crossover points were at 700hz and around 7000hz. The conical horn was a prototype of a unit Bill hopes to go into production
with soon, and I certainly hope he does, because it sounds GREAT. Driven by the RCA field coil 1428B, this horn had everyone
amazed by its total lack of coloration and distortion. The horn just disappeared. Far superior, in my opinion, to the various
horns I have heard, be they exponential or Tractrix. The conical flare is clearly the overlooked shape in horn design, even
though people like A.J. May were building conical horn prototypes at RCA in the 1950's. But back to Bill's horn, not only
did it sound great, it looks awesome as well, evoking the industrial design of 1940's Westrex and JBL horns, and, being cast
with 20lbs of aluminum per horn- no resonance in this design. In the upper midrange, the conical horn clearly revealed the
limitations of the Mill's large RCA multicells, much as I love their sound (and appearance.) The 2004 Mill system may very
well incorporate a pair of these. Bill also brought a computer with horn modeling software and gave a great talk on horns.

Most guests are amp jockeys, however, and they come to plug their kit into the Mill's big RCA horns. With just about everyone
using the same speakers, the Tasting affords a fairly accurate comparison of gear. The day started off phono related- Larry
Welsh was on hand to help tweak the tables, which included the Mill's Technics SP10 tt and EPA arm (in the original Obsidian
Base) and Shure SE1 tube phonostage, and Randy Carter's Empire 208 with modified Rega arm and a Bottlehead Seduction Beta
phonostage. The Empire both looked and sounded excellent and proved a popular source throughout the day. Jeremy Epstein's
6C45 phonostage was widely regarded as definitive, and I would have to agree. Visit Jeremy's WebPages to learn more. Jeremy
also brought his dog and a 2A3 push pull with "iron concertina" phase splitter. I believe the dog was single ended,
though.
To be fair, we usually try to begin with the lowest powered amps and work our way to the monsters, and lowest powered amp
prize usually goes to Nathan Lewis, who prefers to listen on less than a watt, but this year I believe he brought a battery
powered, zero oversampling DAC (TDA1543) passive supply, tvc out. Next in line, and winning the nonexistent award for most
vintage piece of gear, was Tom Ruppert, of VintageAudio.Net fame. Tom is one of the top Western Electric guys in the US, but
he brought RCA stuff this year, knowing that the home team is an RCA team. Along with an RCA OP-3 broadcast amp from 1928
was a 1926 SET power amp using a 210 tube, a 30 DHT and interstage. Next year he is promising/threatening to bring a classic
WE amp and speaker combination to try to challenge RCA supremacy. Good Luck Tom!
Moving up powerwise was Doug Eisemann, AKA Mr. Klangfilm, with a pair of 1960 vintage Telefunken Maihak V73 4 watt EL42
PP monoblocs (originally used as German Broadcasting monitor amps.) Besides being gorgeously built and designed, these little
pentode pp amps sounded wonderful, and had the triode SET purist/snobs sputtering. Doug is promising to bring his ultra rare
Klangfilm F2A11 pp amps for the 2004 tasting, which should be most interesting, as they are considered perhaps the best sounding
of all the legendary Klangilm gear.

Every year the 300B is well represented and this year we had Joe Perucki's 300B SET (6SL7-6BL7) circuit by Jack Elliano with
Jack's Electraprint OPT's and Sophia Electric meshplate 300B's, along with Herbert Jeschke's dual purpose 300B SET, which
he can switch between OTL use for high impedance full range drivers and conventional transformer output.
Infamous chile maven and amp hot rodder Scott Scholl brought a pair of modified Eico HP20S monoblocs with 6B46 and 6H30's
in SRPP and a pair of modified Heathkit AA151 monoblocs with 6H30's, all poly caps. Moving up in power was newcomer Douglas
Piccard, AKA Sector 7G, with some real He Man monoblocs. Doug's amps were so big and heavy he welded steel cages for them-
nice bit of work. They were- PP KT90 monoblocs, full differential amps with a center tap in the OPT for local negative feedback.
Also, a 12SN7 shunt regulated B+ linestage, cascode mosfet CCS throughout.
The Dixie Bottleheads were missing their Meister Builder Jim Dowdy this year, but Jack Welsh brought a new big triode
entry, his latest GM70 SET amplifier, 6DN7/6BL7, etc., low voltage, high current. Hope Jim can make it for the 2004 Tasting-
its always fun to watch the Bottleheads struggling to get a 600lb amp on multiple chassis up to the third floor listening
room.

And that led the way to the biggest, meanest and definitely scariest amps ever to play the Mill- the 1937 RCA 845 PP booster
amps, built as an additional output stage for theaters that needed more power than the usual 20 watts. These were the amplifiers
used for the famous Fantasia road show. After years of scrounging around, I finally made a pair, and we drove them using Herbert's
300B amp in OTL mode, into the input trannies of the RCA amps. The amps use a pair of 845 triodes and a pair of 866 mercury
rectifiers in each monobloc. These rack mount monsters way over 100lbs each, and had pressure switches on the front to kill
power if the rack cage was removed. Of course we ran these with the cage off so we could see the big tubes light up, but with
voltages in excess of 1000VDC everyone was mighty careful while they were on. Their rated power of 60W belies the fact that
they will produce nearly 200W before going into audible distortion, according to Hans Dietze, who used them as reference amps
in the RCA Camden laboratories back in the day. So, how did they sound? Even with super efficient horn loaded speakers, there
is nothing like sheer excess of great power (especially with a 2000 square foot listening room). These amps had that kind
of power. Next year we will have a specially built driver amp dedicated to the sole task of driving the RCA 845 monoblocs,
plus a few others to hear just how transparent this output stage is. But it was clear that the 845 tube in a simple push pull
circuit can be a stunning
