VAC 70/70 III Owners......6SN7, 300B Recomm.

Those of you who have actually had or still have this amp and have experimented with tube rolling with the 300B and 6SN7, I would sure appreciate your comments. Thanks in advance for your time.

I recently purchased a VAC 70/70 mk3 s. where can I find more information about the tubes diagram for the amp? I know it uses two 6sn7 per channel. Are there any differences in functionality between the two 6sn7 used for each channel? For example, do I need to use a matching pair of 6sn7 per channel?

I have one matched pair of RCA red base 6sn7 and a matched pair of Raytheon vt231 6sn7. Can I use one RCA + one Rayheon vt231 for each channel? Thanks.

   "Can I use one RCA + one Rayheon vt231 for each channel? Thanks."      Yes and that's preferable, compared to using the exact same tube, in both positions.

@rodman99999  Thanks. Do you know which sockets are which (splitter, driver) in the 4 sockets from left to right? Can't find that info in the manual. Thanks.
