SEPTEMBER 2010 |
From Bill Perkins of Perkins Electro-Acoustic Research Laboratory! pcX now has back in stock, the "full range" of "new" updated PEARL TUBE COOLERS - without a doubt, one of the most useful accessories in tube audio. Use of these devices result in reduced tube microphony for noticeably improved sonics; and longer tube life (conservatively triple) due to the cooler "heatsinking" the heat away from the glass enveloped, via the thermally conductive copper-finned cooler material. NOTE: PEARL has converted (since October 2005) cooler manufacturing over to a new fin design, which provides over 60% more contact area with the tube's glass bulb/envelope. As a result, the previously supplied carbon fibre sleeve is no longer required for the cooler to work, as intended. Which Tube Cooler for Which Tube? - PDF (recently updated)

TUNG-SOL KT120 Power Tube 
In September of 1950 Tung-Sol introduced the 5881, an up rated and industrial version of the 6L6GA with a 23.5 watt plate dissipation, opening the doors to the hi-fi movement of the 1950s. This rugged tube also found a home in the '59 Fender Bassman and servo amplifiers used in B-52 bombers. In 1955 Tung-Sol raised the bar of high fidelity with the introduction of the 35 watt 6550, which could deliver 100 watts with a pair in push-pull configuration. This tube was used in the Dynaco Mark III and Sunn amplifiers.
New Sensor now announces the Tung-Sol KT120, which has a plate dissipation of 60 watts, making it the most powerful tube in the 6550/KT88/KT90 family. A pair of these tubes in push-pull configuration can deliver power levels of 150 or more watts. When used at the parameters found in existing 6550/KT88/KT90 circuits, the Tung-Sol KT120 is impervious to overload, delivering peak power with extreme reliability and long tube life. However, taking advantage of the higher current handling capacity of these tubes, a very unique and super powerful and stable amp can be designed using the Tung-Sol KT-120.
TUBETS-74158
KT120 Power Tube
pcX Selling Price: $89.95/MP USD
NOTE: In existing designs (retrofit applications), the KT120 can offer from 10 to 25% more power (over a 6550/KT88)...but more importantly, it will be ultra-reliable, with an exceptionally long life, given that it will be operating at only 50% of design maximum. To take advantage of it's near double power capabilities, a new amp design is required, with higher operating parameters, and a much larger output transformer.

SHUGUANG TREASURES HiFi Electron Tubes
pcX is now offering up Shuguang Treasure Electron Tubes. Shuguang is the oldest and largest tube manufacturer in China, established in 1958 by engineers educated and trained in the United States during the late 1930's and early 1940's. Today, Shuguang's vacuum tube production accounts for 40% of the world's total tube output, either under their own brand "Shuguang", or under various OEM brands.
Generic Shuguang tubes come in clear glass bottles. However,
the Treasures series have a carbon compound coating applied inside the tubes making them appearing to be "black bottle" or "black glass". The first Shuguang Treasures tubes were released
in December of 2008, to celebrate both Shuguang's 50th anniversary and to highlight a variety of important technological advancements in their tube production, such as:
a) High Polymer Compound Carbon (HPCC) coating is for the first time used on vacuum tube production. Compared to traditional carbon spray technology, HPCC coating will allow greater concentration of electrons, enhance and maintain stability of the electron flow, maximize "secondary electron emission suppression" from the glass enclosure, in turn reduce effects of electron swirl which generates internal noises from the vacuum tube itself.
b) "Super Alloy" technology is for the first time used in constructing vacuum tube. 'Super Alloy' technology was invented and first used in aviation, aerospace, military and other high-tech market segments. After 3 years of testing under extreme conditions, Shuguang has successfully adopted such technology in vacuum tube construction, to achieve directional solidification and single crystallization, greatly improving the ability of electron emission and electron current stability.
c) Improved vacuum technology during production process, to further improve the signal background
d) Unique triple mica insulating spacers and four independent supporting poles to all but eliminate microphonic effects
e) Gold coated grid and gold coated pins, plus white ceramic base
f) Key assembling processes are manually completed by a small number of senior technicians with 30+ years of experience. These tubes are truly handcrafted.
g) An additional sixty part selection and matching processes are adopted to ensure premium quality tubes, compared to the Shuguang generic clear glass variety.
NOTE: All Shuguang Treasures tubes purchased from pcX are sold in matched pairs - and are closely matched for "both" Ip (Plate current) and Gm (Transconductance). These tubes are sold with a 90 day warranty.

AMTRANS AMRG Series "premium" Carbon Film Resistors
In response to our customer demands, pcX has finally been able to source a carbon film resistor as good as, if not better than, the legendary RIKEN.....it's the Amtrans AMRG. These Japanese-made beauties, are amazingly well built (black anodized aluminum case, epoxy filled, gold-plated copper end caps, gold-plated OFHC leads, etc..) and are sonically the equal of the RIKEN's....and to my ears, their superior.

BURSON AUDIO "shunt" Super (old style) Regulators - 50% Off Special 
Burson Super Regulators are a direct replacement for some of the most commonly used regulators in the market, based on the same technology from Burson Power Supply designs. Not only does the Super Regulator provide the basic function of a standard regulator (with a much lower noise level) it also incorporates a noise filtration network that will screen out a wide bandwidth of unwanted noise from upstream. This will leave the output power stable and noise free. When clean power is supplied to the rest of the circuit, your equipment performs to it`s full potential.
pcX is now please to have these "shunt" type regulators in stock. For more info on these regulators, click here:
NOTE: Shunt type are technically superior to series type regulators - however, they are usually larger, with lower current capability.

PEARL We have just been informed that PEARL Tube Coolers have gone up in price (effective September 1st), on some SKU's...by about 10%. We have adjusted our retail/pcX pricing accordingly. This was due to the design improvement incorporated in the coolers, which now use heat conductive powder coat paint as the finish on the copper finning.
BURSON AUDIO We now have in stock, the latest "generation #3" HA-160 Headphone Amplifier....which has addressed two small problems, observed in its glowing product reviews: the unit no longer has a ground loop....and...the attenuator has been improved with a far more user friendly taper between steps. GOOD NEWS...since the price of $699 remains unchanged...and we are still including free UPS Ground shipping.
PS AUDIO They have announced price increases (effective July 15th) on several of their popular products......including, the Power Plant Premier - which goes back to $1999 MSRP retail. However, pcX has 4 pcs (black) still in stock, which it can offer at $1495 - a 25% discount.
