What tubes are in you Rogue RP-5?

Just picked up RP-5. Not a fan of stock JJs. 
Put in A pair of Brimar CV4003 and a pair of GE Military Stock, both from upscale. Love the Brimars (were my favorite in the RP-1) but unsure about GE tubes yet (weren’t a good match in RP-1 either). 
What tubes are you using in your RP-5 or RP-7?
What tube placement on the board is most critical?

All…thanks! I do plan to give guys at Rogue Audio a call on Monday. 
@stereo5 you sure you are using 12AX7? RP-5 calls for 12AU7 and I don’t see NOS Mullard 12AU7 variant on upscale website.

@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.
