I have had little trouble with the ECONCO rebuilds. I once had a bad (open filament) on a 3CX2500F-3 for a 5 KW AM rig.
I once had a shorted 3CX3000A7 for a 5 KW FM rig. Other than that; I have had good luck. Tube life is 2 or 3 years.
On the problems I have had, ECONCO customer support was very prompt in sending out a replacement.
I did hear that a year or two ago, several folks had problems with them. I think probably a new person doing the rebuild.

I too have had little trouble and good support when I call. May depend how hard Fedx or UPS throws it down.
I better chime in here too. Over the last thirty-some years, we have always received the best service from Econco. Our recent rebuilds have been even better, in fact. I do remember one occasion where we received a tube that wouldn't load well and the replacement was a no-go. They rushed us a third tube and we were set. Sorry for those with bad experiences recently. I don't know what the statistics are on average or for the various kinds of tube builds. Does anybody?
We use the 4CX12000A (BE FM20T). In earlier years it was the 4CX15000A in the Gates/Harris FM20H3.
