Try Mullard 6922's. A friend of mine has a Modulus 3, not the 3A. He swears by these tubes in that preamp and they have lasted him a good two years and are still going strong. Certainly no noise unless you put your ear up to the tweeter. His system also has great bass and great dynamics with these tubes. I think this would be a better match than the Telefunken 6922 in this particular preamp.
Best tubes to use in M3A? Help
Okay, I've tried 3 different pairs of tubes from
2 different sources and they are all noisy. The 1st
2 pairs I tried were 1970's Sovteks from Upscale Audio.
The first pair were dead quiet and sounded fantastic -
for about a week!! I sent them back, and the next pair
I got were noisy from the get go.
I just received a pair of Tungsrams from an independant
guy online and they are also noisy at idle. I'm thinking
of splurging and buying some expensive Telefunkens but I'm starting to think maybe it's this preamp that
is ruining perfectly good tubes. Can this happen? If it
wasn't for that 1st set of Sovteks sounding sooo good,
I would have given up on it by now and bought myself a good
solid state pre. Can anyone who has experience with an M3A
give me some advice with this dilemma? I'm at a loss.
Thanks in advance.
