Be VERY careful about buying "Bugleboy" 6DJ8s. Richardson Electronics bought the name several years ago and sells current production tubes (yuck) with the Bugleboy logo and name. Do not buy any Bugleboys that are not GUARANTEED to be Amperex from the 50s or 60s.
Source For 6DJ8 etc
Can anyone advise a good source for the better/best 6DJ8 and its equivalents. The Amperex 7308 is attractive, but Kevin Deal will not supply anyone outside of the US - or at least that is what he has stated. Are there any other sources that might be more open-minded about their customer base?
