Except for the 3 minute time delay and air requirements, these are great tubes with low drive and medical pulls can be found for under $400.

A Powerhouse!

I spent a lot of time evaluating the 3CX1200A7, GS-35B, and 8877 tubes to replace the aging 3-1000Z in my BTI amplifier. I chose the 8877, mainly because of the lower drive and blower requirements (as compared to the GS-35B) and because the 3CX1200A7 is impossible to find at reasonable prices. 8877's can still be found on Ebay at affordable prices.
The amp was easy to convert and puts out a minimum of 1500 watts on all bands with lower drive than the 3-1000Z. It's a great tube!

Very good tube

I have been using this tube for over 10 years in a Henry 3002 2 meter amplifier. I operate it between 1000 and 1500 watts output SSB & CW and it has been flawless since day one, granted it does not get used as much as my HF amp (commander hf-2500) but it has always been there for me with no problems. It requires very little drive for legal output (aprox. 40 watts). The only thing I do dislike is not with the tube but the blower required to support it, it does move alot of air but makes quite a lot of noise also.

3cx1200d7 is better
|
Time owned: more than 12 months

This is almost the perfect tube. High output, small size, will work at hi/low plate resistances, reliable, long lasting life, Eimac quality. Only down side is the 3 minute warm up. The perfect tube in my opinion is the 3cx1200d7.
