The evolution of guitar amp circuits becomes a revolution! The Ultimate Tone, Volume 6 takes you through advanced DC Power Scaling methods; reveals the secrets of Dumble amps; explores the truth about high-gain preamps; demonstrates how to build Z-B-X push-pull power amps with a single power tube; simplifies the design of 400W+ tube amps - methods that can be applied to any power level; presents class-G tube amps where 100W of output has the same waste heat as a 25W amp; explores modern mains control and sustain circuitry.

Miniature heptode primarily intended to perform the combined functions of mixer and oscillator in automobile radio receivers. Specially designed to operate with plate and screen voltages supplied directly from a 12-volt storage battery.

The Zero Glide® Replacement Nut System borrows the “zero fret” concept to reduce string contact in the nut by up to 93%, increasing tuning stability, playability, and open string tone. It only takes a few minutes to install with absolutely no permanent alteration to your instrument. Zero fret wire included (multiple sizes). Comparison Standard Nut Zero Glide Open String Tone Absorbs energy. Fret reflects energy, making the open strings more vibrant. Tuning Friction causes string binding. 93% less surface area. More accurate tuning. String Bend/Whammy Bar Whammy bars and string bends cause the strings to bind in the nut and not return to pitch Reduces string binding and "returns to zero" after every tug of the whammy bar or bend Durability Slots wear down over time. Minimal wear.

High performance, ultrafast diodes. Improve efficiency, reduce noise, allow higher frequency operation.

Duodecar type tube used in audio-frequency circuits. The triode unit is used as a voltage amplifier; the pentode unit is used as a power amplifier.

Hammond manufacturing 20 gauge steel cover plate. Punched with 4 holes – 3/16” diameter (Chassis now includes ⅛" holes to allow installation of optional bottom plates).

This model offers the same specs and styling as the Original “Milk Bottle" style 102 Series, but with Pearloid Buttons and button retainer. 18:1 ratio.

Made in U.S. vintage spec ABR-1 bridge made to the same specifications as the original 1950s version. Wired with plated brass saddles. Mounting hardware sold separately. The bridge features the vintage-style retaining wire that secures the plated brass saddles and intonation screws onto the bridge.

Hammond Mfg 20 gauge steel 13.5” x 5” cover plate. Punched with 4 holes – 3/16” diameter (Chassis now includes 1/8"" holes to allow installation of optional bottom plates).

Miniature type triode-pentode designed for use as an AF amplifier by triode section and AF power amplifier by pentode section in radio receivers.

New Old-Stock (N.O.S.) tube. The 930 is a gas phototube sensitive to red through infrared light.

Medium-mu twin triode of the 9 pin miniature type intended for use in the matrixing circuits of color television receivers. It can also be used in phase-inverter, multivibrator, and general-purpose amplifier applications

A worthy successor to the Vintage 10, the G10 Vintage is a 10" speaker with bags of attitude. Using powerful ceramic magnets and the same voice coil design as the Vintage 30, the G10 packs an impressive punch with its 60W power handling. With the fast response of a 10" but with the strong and creamy vocal tones of a 12", the G10 is the ideal choice to add depth to hollow-sounding amps, or for players who want to get humbucker-type girth from single-coils. Can be used singly to add vocal warmth to small valve combos, or in quartets for a weightier but still lively attack.

Miniature double didoe, high-mu triode intended for use as a second detector audio amplifier. It is designed for operation where the heater and plate voltages are supplied directly from a 12-volt automotive storage battery.

Alpha Mini Pots with solid shaft and short PC mount terminals.

• Threading: M7 x 0.75
• Distance between terminals: 5 mm (0.197”)

• Over designed for single ended tube output circuits (triode, tetrode or pentode tubes).
• Enclosed (shielded), 4 slot, above chassis Type 'X' mounting.
• Frequency response at least 20 Hz. to 20 Khz. at full rated power (± 1 db max. ref.

Transmitting triode

Phillips panhead machine screw, M3 metric, zinc. Designed to go through a hole or nut that is pre-tapped to form a mating thread for the screw. Phillips drive is the most common drive used and is designed to "camout" when the screw reaches optimum tightness, thus preventing damage to the screw head. See S-HS-M3-6-X for colored 6mm M3 screws.

Heater-cathode type transmitting beam power amplifier in the 9 pin miniature construction. It is intended for use in compact, low-power mobile transmitters and in the low-power stages of larger fixed station transmitters.

Low cost, high quality 3.5mm patch cables in a variety of lengths and colors. The cables are super flexible, have a great droop, and are shipped coiled so no permanent kinks are formed. With the large selection of lengths and colors, these cables are the perfect choice for any sized system.
