Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: Rogue cronus

I have one and really like it. It is a great value and impressive regardless of price (I've had a bunch of separates through here over the last several years costing significantly more than the Rogue). My speakers are the 87db efficient Aural Acoustics Model B three ways (time and phase coherent, Seas Millenium tweeters).

The stock tubes (although not bad) do limit the sound quality and really should be replaced. The Genalex reissue KT77s or KT66s and NOS Sylvania 6L6s all sound excellent (the latter two being more linear/neutral as befits those types: they need to be biased one or two milliamps higher than the EL34 family). If you have money to burn, the new Shuguang Black Treasure 6CA7s are stunning (check out Parts Connexion when they have a 20% off sale).

For the 12AX7s, I like 1970s NOS pieces from Japan, new gold pin Tung Sol re-issues, or Groove Tube 12AX7Ms. All are reasonably priced.

Also at reasonable prices, NOS Raytheon or RCA 12AU7 blackplates (particularly OEM tubes for Organ companies: try Brent Jesse) are excellent in the amp section.

For the preamp section (only one required), I like a Mullard CV4003 or a RT 12AU7. An RCA cleartop is another choice.

One last thing: upgrading the fuses (six) to aftermarket ones makes a very large difference (particularly for the money) in clarity and resolution.

Good luck.

EDIT: Forgot to mention that the KT66s and 6CA7s will require socket extenders to fit.
