Hi Folks,

I have had very good tube life traditionally out of my rebuilts in my transmitters, getting 18 months to two years on average (various 5KW, 10KW, 25KW, and 35KW boxes).  From time to time we will get a few tubes that don't last but it seems that we are getting more weak ones than good ones over the past year.  At one time or another I have used just about everything out there but have been using Econcos more recently simply because of availability.  When Harry (Freeland) was rebuilding I frequently got tubes that lasted over two years.  They also made more power than the others at least for me.

Hopefully someone will step up to the plate and get their quality control up to snuff.  Thanks for all the comments.  Looks like for the most part everyone else is experiencing the same thing we are.  :-)

Tommy, Richardson just resells Econco rebuilds.  CPI owns Eimac and Econco.  Now that they have also bought out Freeland, there are only two rebuilders left in the country:

1. Econco

Kennetron can be expensive for some of the smaller radio tubes, but they do good work.  

Kevin, funny...I have two Energy-Onix Eco10 boxes that use YU148 tubes, one of them running 11.5kw (don't ask), and I have been getting great life (3 years on one, 2 years on the other) from Econco rebuilds.  The CCA 10000G boxes that I have never get more than a year.  Basically the same box from an RF perspective.
