I used to own an EAR HP4, and posted some tuberolling experiences on Head-Fi.org. A search there should turn them up. The HP4 is designed around the stock Sovtek 6SL7GT, which is a short-bottle tube. The older tall bottle 6SL7's won't fit under the cover. I wound up having someone build a new cover for mine so that I could use the taller tubes. That said, I noticed a disporportionate amount of wear on the output tubes when older NOS tubes were used. This was only apparent on some brands, and only on the output buffers. Gain tubes seemed to wear much better.
