Triode, Dual, Telefunken Brand - Smooth Plate

Triode, Dual, Telefunken Brand - Ribbed Plate

Triode, Power Amplifier, Single Plate

Miniature medium-mu twin triode in which each section exhibits a remote-cutoff characteristic. It is designed primarily for use as a cascode radio-frequency amplifier, intermediate-frequency amplifier, or mixer

RCA, Beam Power Amplifier, Black Plate

Mullard brand. Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.

Compactron beam power pentode primarily designed for RF power output applications. Features of the 8950 are dual cathode and grid connections for lower lead inductance, and a 13 volt heater.

Telefunken, Pentode, Power

12AX7A - Triode, Dual, Amperex Bugle Boy Brand

Power pentode of the glass octal type. This tube is suitable for all applications which require peak powers of up to 11 watts from a single tube or up to 100 watts from two tubes in the normal push-pull arrangement.

9-pin miniature triode with an indirectly heated cathode. It is intended primarily for grounded-grid operation in the input stage of broad band amplifiers.

RCA brand. Miniature high-mu twin triode each section of which has an individual cathode connection - especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits.

The 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent.

Amperex Bugle Boy, Pentode, Power

The EL84 is an output pentode rated for 12W anode dissipation, primarily intended for use in a.c. mains operated equipment.

Genalex Gold Lion PX300B power triode tube with gold pins. Made in Russia. In Europe during the 1930s the GEC (Genalex)/Marconi-Osram PX4 and PX25 power triodes were considered the finest audio triodes of their day. In keeping with the tradition of Genalex to provide the highest quality tubes, New Sensor has released the Genalex Gold Lion PX300B audio power triode. This tube is the highest quality 300B type available and is considered to be an upgrade in any 300B amplifier.

The 801A is an RF power amplifier, AF power amplifier, and modulator
