Default 6E5P

What is the life expectancy of the russian tube 6E5P, 37mA at 210V?
Some people say that is too short, 500h or even less
Is that true?
regards Jaime

However, the manufacturer would not accept complaints if it serves more than 500 hours, but your particular mile may vary.

Yes 500 hours is the manufacturer's warranty, but the life expectancy?

Unpredictable.

I never saw 6Э5П tubes in civil equipment, but I can't imagine 6П14П or 6Н1П to serve 500 hours only like specified in their datasheets. If a TV set was up 16 hours a day it would be 500/16 = 1 month of life for all tubes. Can you imagine that? When I managed railway division in USSR we could not complain if tubes were working less than 500 hours (well, 5,000 hours for 6П3С-Е that were driving long lines). Actually, we never could complain because they lived much longer. But in case of equipment failure during some accident guilty (as the result of investigations when all involved tried to find each others mistakes) could easily go to jail. I don't remember when manufactures of tubes were called guilty.

Thanks for your response.
Yours is a convincing argument.

Default 6e5p vs 6e5p-i

I accidentally bought 12 6e5p-i on ebay. Does anyone know if they are as well liked for use in audio as the standard 6e5p?

Also, I've noticed from ebay that the 6e5p is made in at least three factories Reflektor, Saratov and Voshod. Is there a generally acknowledged favorite among these?

Thanks - M

Hola Jaime ..

Hi Jaime, you can see website of Romy The Cat, there are a lot of information.
I use the 6e5p as driver in Gu50 SE at 190V 27mA.
Maybe 37mA is a little high?
Romy recommend changing this valve once on year.

Saludos,

Alberto.
