Review Summary For : Greenstone 8877/3CX1500A7
Reviews: 1MSRP: 745
Description:
The 3CX1500A7 / 8877 vacuum tube is designed for use as a cathode-driven Class AB2 or Class B amplifier in audio or RF applications including the VHF band or 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 drive requirements exceptionally low for a tube of this power capacity.

Not good Time Owned: 6 to 12 months.
Needed to replace the 8877 in my Alpha 9500. First Greenstone 8877 lasted less than a year then died. Never over driven. Replaced under warranty. Second one lasted about 3 weeks then died. Also replaced under warranty.

Switched to Taylor from RF Parts. So far no problems.
