Let's share secrets of Lamm 6C33C tubes


Lamm owners please share your experience on the 6C33C tubes in relation to the V1 and V2 positions.

I know the Lamm is very specific with their factory tubes as to which tubes goes where but I guess many owners would have brought from other suppliers and did the matching themselves.
I found that nearly all tubes work on the V1 position but not on V2. Now, I brought tubes from The Tube Stores and they marked them with range between(18 - 39)! I wonder what would be the best combination? Anyone knows the secrets?

6c33c does need testing/matching in BAT. The nature of "balanced bridge" dictates matched by plate voltage offset.

Call Victor and he should be able to explain in-depth if needed.
