upgrade what

Sometimes it's the music you listening to.

Thanks for your comments and suggestions. The tubes in the Rogue Cronus integrated amp are: two PSVANE 12AX7, three PSVANE 12AU7 and four PSVANE KT88-PT

Any feedback would be welcomed. I don't know much about the sonic characteristics of different tunes. 

Thanks again

@bzawa , Hi , unfortunately Rogue like many ran into a tube supply issues. The Dark Rogues used to have Tung Sol KT 120’s, Telefunken 12AX7’s and RCA 12AU7’s. They ditched the Tung Sol’s due to availability and reliability issues. They ditched the nos input/phase/driver tubes due to lack of availability and exorbitantly high prices. Your amp will have more bass and power with Tung Sol KT 120’s, but less treble. The two 12AX7’s will have the most influence on your tonality. Last summer I had my Rogue M-180’s updated to “ DARK “ , Rogue tubed them with new production Tung Sol 5751 gold pins in the 12AX7 slots. I subbed a $300 pair of nos Telefunken 12AX7’s and it was too bright. I really like the Tung Sol’s but they have a mu ( gain ) of 70 and 12AX7’s have a mu of 100, hence a bit less output, but a smoother sound with less noise. If you’re willing to spend the money try Tung Sol KT 120’s X 4, new production Gold Lion 12AU7’s. Try the 5751’s or a nos set of 12AX7’s ( not sure what ) or the 5751’s. All said you’re looking at $1K to spin the wheel. FWIW I’ve been told by @mulveling there is a Rogue owners group on Facebook. I also tagged him on this as he’s a great source of humble knowledge regarding Rogue Gear. Respectfully, Mike B. 

@buellrider97 Hello Mike Thanks for all of that info. In February, I had the the Cronus Magnum lll upgraded to the dark version. Along with the new included signal tubes, I had them replace the rest of the tubes. Question. Which are the signal tubes? The bigger ones, the smaller ones or some combination of the two?Also are these PSVANE tubes of the same quality as the ones you mentioned? Thanks, Bill

2. Preamplifier Tubes (2x 12AX7)

Positioned near the front of the amplifier, these are the first tubes to receive the audio signal coming from your sources (like a turntable or CD player). They act as the voltage amplifiers, boosting the weak incoming signal and preparing it for tone shaping. The 12AX7 is famous for its high gain and imparting a warm, detailed character to the sound. [1, 2]

3. Driver/Phase Splitter Tubes (3x 12AU7)

Situated between the preamp and power tubes, these act as the "driver" stage. They take the signal from the 12AX7s and divide it into two opposing phases to feed the push-pull power tubes (the KT120s). They also act as buffers to ensure the signal remains clean before hitting the heavy power stage. [1, 2, 3, 4]
