EAR 834p Tube Upgrade/Replacement

I have been told the primary tube to replace in the EAR 834p phono pre-amp is in the first position. Is the first position closest to the front of the unit? I have ordered some NOS RCA 12AX7 replacements tubes to try.

The tube with the most potential through upgrade is, in fact, the one closest to the front; but, that position is V1. The middle tube is V2, and the one in the rear is V3. Having said that, and as Stevecham points out, I have experimented with different tubes in all three positions with good results. Unlike him, in my system, best results (by far) were with the Telefunkens. Good luck.

As I said, there is often confusion, including mine. I got it completely backwards. What I meant to write is that the front tube is actually V3. Middle tube is V2 and rear tube is V1. It seems counterintuitive but that is the way it is configured. Anyway, do start with the front tube (V3). Good luck.
