MidFi+ Damping Instrument

HAL-O 9 MidFi+ Damping Instrument Delivering a surprisingly linear frequency response, MidFi+ tends to induce a subtle, gently rising bottom end, great for modest systems that are a bit lean on the bottom. A slightly more solid bass, without "bumps" or "valleys," together with increased clarity and reduced microphonics throughout the frequency spectrum results in a very pleasant and dynamic listening experience.

For small-signal input/driver and preamp tubes only.

Fits miniature nine-pin tubes, including 12AT7/ECC81, 12AU7/ECC82, 12AX7/ECC83, 12AY7, 12AZ7, 12B4, 12BH7, 12BY7, 12BZ7, 12FQ7, 2C51/396, 417, 5670, 5751, 5814, 5842, 6189, 6201, 6267, 6350, 6414, 6688, 6829, 6922, 6955, 6973, 6AN8, 6BL8, 6BQ7, 6C45, 6CG7, 6DJ8/ECC88, 6FQ7, 6GC7, 6GH8(A), 6GU7, 6N1P, 6N3P, 6N6(P), 6U8(A), 6V4, 7025, 7044, 7119/E182CC, 7199, 7308, 8416, EC86, ECC85, EF86, EL86, EZ80.

"These work great. Especially on older 6V6 tubes."--Sam Gevorkian, Palm Springs, California


Other Items:

Balls-

Fluorite ball, 25mm-28mm diameter: $3.69 ea.

Fluorite ball, 30mm-34mm diameter: $2.49 ea.

Frosted acrylic ball, 1" diameter: $.39 ea.

grungebuster ball, 1" diameter (great plinth/frame interface): $16.49 ea. Extra-firm, slide-proof ball is formulated to block and absorb micro-vibrations that adversely affect parameters unique to turntables. Super-fast compression/deflection without resonance produces a livelier audio response than "slow" materials like Sorbothane or "unhappy balls," and a more natural musical presentation than rigid coupling.

grungebuster ball, 2" diameter (superior "Cloud" upgrade): $42.50.ea. Makes a fantastic "seismic sink" DIY sandbox (just partially bury three or four balls -- laterally spaced -- in a sandbox, then set your platform on the balls).

Macassar ebony ball, 7/8" diameter; lathe-turned in the 1960's: $2.49.ea.

Footers-

Big Fat Black Dot, original formula: $9.65 ea.

Misc-

Electronics damper, .050" ID (stretchable), 3/8" OD, 1/4" wide, platinum-cure silicone, clear: $1.98.ea.
