BRAND NEW 3-500Z tubes

[Multi-Volti Devices]

Anybody know the mu of these 'new' tubes.

Somebody said 'original' specs on the list awhile ago.

Eimac supposedly lowered the mu from 200 to 160 years ago, allegedly to help
reduce parasitic problems (not in the tubes, but to ease the difficulty of
preventing them in application circuits).

Further allegedly, the Chinese tubes (Penta?) are 'copies of the Amperex
design', which retained the mu of 200 (Quoting Rich Measures, AG6K).
