3CX10,000A7
$2,199.95 Add to cartThe Penta Laboratories 3CX10,000A7 amplifier tube for sale is a ceramic and metal power triode intended to be used as a zero-bias Class-B amplifier in audio or radio-frequency applications. Operation with zero grid bias offers circuit simplicity by eliminating the bias supply. In addition, grounded-grid operation is attractive since a power gain as high as twenty times can be obtained with the PL8160/3CX10,000A7.

3CX1500A7
$1,149.99 Add to cartThe Penta Laboratories PL8877/3CX1500A7 amplifier tube for sale is a rugged ceramic and metal power triode designed for use as cathode driven Class AB2 or Class B amplifier in audio or rf applications, including the VHF band. It can also be used as a cathode driven plate modulated Class C rf amplifier. As a linear amplifier, high power gain may be obtained without sacrifice of low intermodulation distortion characteristics.
Low grid interception and high amplification factor combine to make the PL8877/3CX1500A7 drive power requirements exceptionally low for a tube of this power capacity.
