What kind of tubes for the m125

Just curious.
Owners of the m125, what tubes are you using? Output, Rectifier, Phase and Driver tubes.
2/4 Output tubes.

My list
KT88's (2)
Phase GE12BH7A
Driver CV4003
Rectifier Mullard GZ33

Thanks,
Frank

KT 120's (4)
Driver GE12BH7A
Phase GE5963
Rectifier Weber WZ68

Mine are still being reconceptualized but I already plan on using KT120s. Not sure about driver tubes. Probably will find some older 12AU7/6189/5963.

KT88
Driver tube Raytheon 12AU7 black plate/ or Mullard CV4003
Phase RCA 12BH7A clear top
Rectifier Weber WZ68
Put away in the safe drawer Mullard GZ33

KT120 on one amp, Genalex KT88 on the other, both x4
GZ37 rectifier, one Haltron, one Mullard
Tung Sol 12AU7

pedrocols,
Seems like you'd have the GZ33 in the amp and the Weber in the drawer?

KT 120 (2)
Driver: Tesla ECC 802s
Phase: Rogers 12BH7A
Rectifier: Mullard GZ37

If you are asking me...you are correct, however I am considering some changes.
Lots of ideas but near empty pockets.
Need to save some coin or rob a bank!

LeGrace...your setup is the most intriguing. Why such diversity with your tubes and what is your impression of what your are hearing other than you love what you hear.
Also what speakers are you driving with your m125's.

I am conducting a long term A/B comparison test so see which I prefer...actually I need to relieve some pressure on the CC before I can even consider another quad of 120's. Speakers are venerable Tannoy D700's. Great synergy with the M125's.

Nice looking speakers...I never heard them but very appealing looking.
There is NO RELEASE VALVE ON THE CC

I use Tung-sol KT120 output tubes and JJ 12bh7 driver tubes with Mullard GZ37/33 rectifiers.
