Dodd Preamp Question

Amperex tubes are worthy recommendation.
Cruz is right about their characteristics and it could prove to be good starting point in fine tuning your system in the right direction.

P.S
I've also used Amperex Bugle Boys in my Dodd and they were quite good as well. Not as "middle-rangey" as Mullards but proportionaly balanced throughout the frequencies with touch of exitement and sparkle.

Good tube comments above. I currently use a pair of Tungsrams,which are kind of a poor-man's Amperex. The Mullards will be warmer, too much so for my personal preference. The Dodd will let you hear the differences in each of these tubes. IMO, the JJ's aren't bad, but definitely are tonally on the cool side. It's worth trying a few different kinds. I'm guessing you'll be very happy once you do. Cheers,
Spencer

I now have NOS Mullards and Siemens CCa (the best of ALL 6922 variants according to many in the know).

I'll try both and report back.

With the stock tubes the Dodd is very good but just occasionally exhibits a bit of treble glare/hardness.

Ok, well, the Siemens are so good I don't know if I'll put the Mullards in. Better all-around. Glare definitely gone. One of those no-doubt, don't-have-to-listen-hard changes.

Heard from few guys about Siemens tubes.
They are very happy using them. I haven't try those yet but I sure will give it a try.

Thanks for sharing your impressions.
