Thanks. I did some further seach on the web, and it seem,
that many come with 5881 (not 5881WXT). There ara slight
differencer between these tubes and between the EL34 as
well. However, as I know, they can be operated in an
overlapping range. I suspect, that the STEREO 50 needs
some fine tuning to operate correctly with a non exact
replacement tube. This week I will meet with a fellow, who
were involved in tube amp design for 10 years. Perhaps
afte that things will be clear.
Anyway, does anybodey know what's the difference between
the 50 50 and the STEREO 50?
