EAR 834p Tube Upgrade/Replacement

Thankful, there is often confusion about tube locations in the 834P. 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.

The Telefunkens, though very nice and a close second, were a bit too smooth and soft for my tastes

Wow! 1st time I hear Tele ribbed plates are soft.

Thanks for the feedback. I will start with V1 and then go from there.

Thankful, my apology. 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.

My dealer, who is also the local EAR service center, and a gentleman that mods the 834P, both highly recommend JJ88's. I think. I can double check if you're serious.

When I was considering purchasing the JJ's I found out that my EAR already had them ATOS. I was told that, around the time I purchased mine, that EAR had begun shipping units with the JJ's. But, mine were "short" or "medium" plate, and so still being curious, I purchased a set of "long" plate JJ's.

I don't remember noticing a huge difference, or even a medium difference in the sonic character between the JJ's -- the short or medium plate and the long plate. But, I kept them anyway sinhce it never hurts to have an extra set of tubes. And "long" plates are the ones that are currently in my 834P.
