[SBE] Anyone have any experience with Greenstone tubes?

[Ron Castro]

The tubes might be Chinese imports, but Greenstone has a pretty good reputation from what I can ascertain.  Henry Radio used them in their HF amps with good results for several years before they stopped making them.

  Hello everyone !

   

  Anyone have any experience with Greenstone USA transmitting tubes?

   

  An FM station here in New Mexico needs a 4CX3500A - and the best price so far (barring tubes of known Chinese origin) seems to be from Greenstone, USA, a company I've never heard of. The station's engineer asked me if I'd had any experience with Greenstone.  I haven't.

   

  When asked "Who makes your tubes," the company representative responded "We do."

   

  Their web site shows a number of tubes in its opening screen picture - interestingly no manufacturer's names or logos can be seen on the tubes themselves. The web site says that the company "makes and distributes tubes" so it would appear that the company doesn't necessarily make everything it sells

   

  Any reports of experience in the field would be most welcome!

   

  Many, many thanks !

   

  Mike/
