Isn't the HG+ nothing more than a selected Chinese 12AX7 tube?
:confused:
 
I've found this:

The new 12AX7AC7 is the latest tube developed at Ruby factory. It is the quietest of all Ruby 12AX7 type tubes, both in terms of microphonics and mechanical noise.

To eliminate the mechanical rattles, a new tighter tolerance mica supports were designed along with a new redesigned plate structure. New assembly controls were added to make the RUBY 12AX7AC7 free of mechanical rattles caused by the vibrations inherent in a high gain combo amp. The famous sweet tone on the Chinese 12AX7 tubes was preserved. In the process, a significant reduction in the microphonics were realized with this tube. The new tube has the same high gain as the very popular 12AX7AC5 tube, just quieter.


So i think AC7 tubes sound like AC5 just less microphonics and mechanical noise.

The standard setup for Diezel should be:
-AC7 HG+ v1,v2
-AC7 HG all other position.
 
I don't really know which Rudy Duolos sent to me, all I could see some HG on them, but they were really good. I loved the way they sounded in the Herbert.

Wrong, the AC5 tubes sound different than the AC7s.

Diezel recommends :
AC5 HG+ Diezel selection for V1 und V2
AC5 HG for the rest
 
I've got the 12AX7AC7 in my VH4 and I like them a lot.

How do these sound different than the 12AX7AC5s?
Has Peter tried them in the Diezels?

To be honest, I don't know if Peter already tried them.

I e-mailed Magic Parts about them, and they said that they do sound different.
 
better a night with the best sounding amps and tubes or a night with Alizée? :) :D[/quote]

That's a hard call :confused: , but Alizée is married, and so am I.
I'll be happy with a night of great amps and tube tone. :lol: :LOL:
 
Late to the party on this one. 'a long plate Shuguang..
