What tubes are in you Rogue RP-5?

Audphile1

you are correct, it is 12AU7. I got mixed up as my McIntosh C2500 uses the 12AX7. I did buy the NOS Mullard which I did buy in 2016 from Upscale. However, they were CV4003 NOS Platinum edition from Upscale. They were produced in India so Upscale was selling them for $75.00 each at the time. Kevin said they were the same as the ones made in England but because they originated from India, he was giving a discount on them.   I looked at my original receipt to verify. 


I was surprised how quiet they were being NOS from the 60’s.

i had an RP7 and tried a whole drawers worth of different 12AU7s that i had on hand from my old cronus magnum and RH5 preamp.  
it simply did not sound any better and often worse than the stock JJ.  
this included brimar, amperex, mazda, philips, sylvania, multiple RCA, mullard, GE and other new production including tung sol, sovtek, genalex.  
RP7 is not the RP5 but i shared my experience nonetheless.  try a few and if no luck give up.  

@stereo5 ok got it…thanks! So basically the same as a pair of Brimar cv4003 I have in there now.

Avanti…
Thanks! Yes the GE don’t sound good in the rogue preamps. They never did it for me in the RP-1 and sound the same which is woolly and mooshy in the RP-5 now. Would fit a bright system well I guess. But I find the Brimars to be clear and transparent. Thinking to just get another pair from upscale. Wondering if mixing a pair if Brimars with a decent pair of different tubes would yield good results.

Well I’m happy to report that I like the RP-5 a lot so far!
I have placed the two Brimar tubes in second row and two stock JJs are in the first row. This was the first improvement. The second leap forward was when I moved the power cords around. Landed on a completely different power cord placement than what I used with the RP-1. 
I must say that the sound now is simply incredible! The RP-5 preamp with Stereo 100 amplifier is an excellent combination.

In the 20 months that I owned one, I really loved it.  Only reason I changed it is because I went all Mac.
