Friedman Small Box & Tung Sol 12ax7's

[John 14:6]

I am still running the stock JJ/ARS EL34's in my Small Box and I have been using an RFT 12ax7 in the V1 first gain stage for a while now. I just recently pulled the stock Chinese V2 and V3 preamp tubes and put in a couple New Sensor/Tung Sol 12ax7's in V2 and V3. The amp has never sound better. This tube combo is just amazing. I have heard some people say that Tung Sol's don't last long in the Cathode Follower and Phase Inverter positions so I will need to see how things go before buying some spares.

Yup I'm sure they will fail in those spots but we will see. Maybe you will be lucky.

Is the V2 spot the Cathode Follower?

I think v3 is the cathode follower and v4 is the phase inverter. But that's honestly assumption on my part.

I'm really happy with TAD el34's Chinese pres and tungsol in v1. Don't feel like there much more room for improvement.

The Small Box only has three preamp tubes so I am guessing V2 is the Cathode Follower.

Yes it is

I just got a Smallbox the other day and was thinking of doing some tube rolling, as I have some new Tung Sol 12AX7s laying around and really like them in my Marshalls. Am I playing with fire by installing them?

The Tung Sols I have in V2 and V3 in my Small Box are still working and sounding awesome. So far.....so good.
