Silk
Audio Grid Choke - SQ Supermalloy Grid Choke,
bare (no potting)
It has a center tap so it can be used for phase splitter in push-pull design. Replacing your grid circuit resistor with SILK Supermalloy Grid Choke is one of the easiest fine-tuning processes you can do by yourself. Our Grid Choke can be characterized as "Super Inductor" since its inductance is more than 4,000 Henry at 20Hz while having very low DCR of just 1.3K ohm. Result is low resistance to DC to bleed to ground (compare typically grid leak at 50k-100k) AND very high impedance to signal so all of the signal is delviered to grid.

Blokker:
Must-have module if you have power
transformers in your gear.
Just connect the red wire in series with the neutral of your mains
supply, blue wire to transformer primary side and kill DCv dead.
Also removes destructive harmonic content created by other electrical
devices loading your power matrix. Most AC supply has some DC
offset present. DC is the enemy, robbing a power transformer of
efficiency and often making it hum. Blok it, and the transformer
can do its job, Sound improvement can be major depending on your
line conditions. Small enough to fit in most chassis. 5cm x 5cm
x 2.4cm. 3A/240V. Tube not included!

Silk
Interstage Transformers are best characterized by:
1.Wide bandwidth due to special winding arrangement for each particular design and impedance 2. Best low frequency response due to its high inductance compare to its competitors (2-3 times lower in THD at 20Hz is typical for SILK interstage) 3. Best high frequency response even when apply direct current up to 2.5 times its competitors allowing the use of low Zp tube with high current requirement 4. Very tight unit to unit, coil to coil tolerance in terms of response curve, inductance, DCR and square wave shape 5. Designed and Developed under real tube circuit to be used Selected best material and precision wound for best signal transfer and sonic purity. Connections are made via terminal lugs underneath. |

Audio Supermalloy
SQ annealed Core MC Step up. 10x and 20x, stainlesss shielded
can, 25/100 ohm input impedance. Utilizes best
selected Supermalloy core. Supermalloy core are all different
in quality. The best one is as much as 50% better and enables
the exotic and propietary winding scheme used. Developed to compete
against top rated step. It can be wired as 1:10 or 1:20 with guaranteed
better FR response than even Ortofon T-3000 (+$1,600USD). beautiful
stainless 5x7cm can with mounting brackets.
SILK Supermalloy MC-step up transformer with Nano Winding Technology: not all MC-step up transformers are the same! SILK Supermalloy MC-Step up Transformer takes several steps to design and build better transformers. The core material uses the best Supermalloy Nickel/Cobalt alloy core in the world to provide the highest inductance with lowest copper turn to allow extreme Nano Winding Technology that extends the frequency bandwidth with lowest phase shift and highest signal transfer. Nano Winding Technology is Silk's exclusive technique that starts with super small OFC wires (much smaller than human hair) woven to to extend high frequency by increasing the skin area of conductor (skin effect). The copper wire is also wound perfect lay to help maximize signal coupling. Silk's
design reduces cartridge distortion by providing theoretical loading
(true loading) down to 20Hz. Lab testing has proved that although
most signal information on LP are consist of mid-high frequency
due to RIAA standard, loading theMC-step-up transformer with true
loading down to 20Hz helps lower throughout audio band. |
