‘I heard farther into each performance, there is really nice dept…’

I have about ten hours into the new Psvane tubes so I bet they haven’t broken in yet.  I do want to post a very postive response to what I am hearing so far.

‘They best the much more expensive Siemens tubes, in every way’

About three weeks ago, I received four Psvane/Pavane 12AT7-T tubes for use as input and driver tubes in my Vacuum Tube Logic MB-125 monoblock amps. The Pavanes replaced a one-year old set of NOS Siemens ECC81s purchased from one of the best and most reliable tube vendors. I’ve owned the VTL amps for 11 years and previous input and driver tubes included the stock GEs, JAN Phillips, Sylvania gold pin 6201s, and two sets of the Siemens.

‘fully Shuguang-ed Mac’

by customer Atom shop:

I’ve been familiar with the Chinese Shuguang brand of tubes for some time. I’ve got a very rare collection of the original nickel-plate 7025 Select Silver Series which went out of production long ago. Bellari used these in their early VP129 phono preamps. McIntosh has used the comparable grey-plate 12AX7 version in their gear. (my own Mac’s stock tubes)
