currently using Rotel RB1582 MK II.
Iam looking at soundstage, details and imaging improvements and read that many are happy to match the MC 452 with C2300,2500,2600.

Thank you.

Same tube Sir & if you don't use a TT, you can leave them be.

12AX7: the original version of this tube. This can only be used in parallel filament circuits. This is not a big deal as virtually all audio equipment is of a parallel filament design.

12AX7A: This version can be used in series or parallel filament circuits. Sometimes, 12AX7A tubes made for the US Military are labeled 12AX7WA, and have seen WB and WC versions. The W is the military type code, A,B, and C are progressively later productions.

Quite a few McIntosh owners seem to be happy with the reissue Gold Lion Gold Pins. Tube rolling with various other brands can yield favorable results as well, but can start to be expensive when one amasses 12v tubes from GEC, RCA, Sylvania, Telefunken, Siemens, GE, Amperex, Phillips and the list goes on.

Best to you,

Bob

I don’t use a TT. Will those tubes burn out at some point and need to be replaced (I assume the heater is running at least)? I recall a discussion in another thread talking about needing working tubes in place, or it could impact sq.
