RK100 - NOS Valves

Post by clark81 » Sat Aug 30, 2014 1:36 pm

Hi guys, I recently bought a Cornford Rk100 and couldn't be happier...
I changed the JJ preamp tubes with 4 TUNGSRAM NOS 12AX7 and the amp came to life!!!
Dynamics, tone, tight bass, silky treble, killing mids...

I am thinking of putting some NOS RFT EL34 instead of the JJ's that I have now (which sound great in the output section by the way)

Anyone has any experience?

Thanks in advance

congratulations on the RK...bliss!

No experience with the RFT's...I use Groove Tube EL34Ms (Mullard dual getter clones) in mine (with EH 12AX7 pre's) and they are very nice tubes.

If you try the RFTs let us know how they do in the beast?
