Thanks Garey. I have tried 3 tubes altogether, including my own spare and a
second I purchased online. The original is a 6EH5, the spares were 6CA5. I
believe (hope) there is no material difference. All behave the same way.
The one I ordered turned out not to be a new tube by any stretch of the
imagination. Where do you like to buy tubes?

Randy -
Sounds like a classic case of a 'gassy' (grid emission) tube. Replace it!
