Has anyone tried any of these. There was a guy advertising them for $88 each plus shipping and since I need a couple I was considering trying them.

Any advice appreciated.

I have tried several , I can tell you this , they do not hold up at all. Pay the extra few bucks and get the better ones.

I haven't had any luck at all with Chinese tubes.. Most have prematurely failed. As with most Chinese merchandise, their tubes are of questionable quality.

Hi guys, I have found the Russian Tubes to be great.
There is a Domestic and Commercial Factories.
If you want, I will try and find my List.
They are avaiable at Antique Radio Supply
