Where to find 12AX7AC5 HG+ 678?

[Metlupass2]

What does the 678 mean and can I just use the 12AX7AC5 HG+ in V1 instead at no noticeable difference? They seem impossible to find.

Are the stock tubes still

Preamp tubes:

V1 = 12AX7AC5 HG+ 678
V2 = 12AX7AC5 HG+
V3 to V6 or V7 or V9 = 12AX7AC5 HG


I did email Peter but he's out of tubes at the moment.

Thanks

FWIW my 2017 VH2 came stock with a tung sol cv4004 in v1.

Actually found one direct from Ruby. They don't advertise them on reverb or their site but they have em.

And did you have to call to ask about the HG +
