Mike,
I just ordered the JJ 2a3-40's for my Stereomour II (and the JJ ECC81 goldpins for the driver tubes) based on the reviews on this site. Had zero problems with the original Sovteks, just looking to get to the next level. The problems you heard about have been resolved and Eurotubes again has a 6-month warranty. You can allay your concerns by calling Eurotubes - they are very familiar with the Bottlehead products. I'll report back when I receive them with my listening impressions. Someone also posted a picture of the JJ's next to the Sovteks, and the JJ's are huge. We'll soon see whether size matters.
