Hi,
i'm asking if the content of this thread:
viewtopic.php?f=14&t=47111

It also applies to the VH4 preamp tubes or is only for the Herbert.

Herbert:

V1 Used by all channels

V2 Used by channel 3

V3 Used by all channels

V4 Mixer & Loop Driver

V5 Return Driver

V6 Phase Inverter

VH4:

V1 Used by all channels

V2 Used by channel 4

V3 Used by channel 2/3/4

V4 Used by all channels

V5 Mixer and Send buffer

V6 Return driver

V7 Phase Inverter


Vh4 has one more preamp dedicated to channel 4.
So if i change to: ruby 12ax7ac5 hg/hg+
where should i put the high grade+ tubes?
Of course V1 and V2 or is better V1,V2,V3,V4 and V5,V6,V7 with the hg?

example:

v1 =hg+
v2 =hg+
v3 =hg+
v4 =hg+
v5 =hg
v6 =hg
v7 =hg



thanks.
