reviews from Stereophile:
The Italian-made Angstrom Audiolab Stella
tube phono preamplifier ($13,670) was beautifully built
inside as out. Look past its glossy lacquered, wooden side cheeks
to find point-to-point wired circuits...I discovered right off
that the inputs were reversed (the left channel was the right
and vice versa). Mr19).
2. To the Publisher: I recently
purchased The Wood Fire Handbook by Vincent Thurkettle
and enjoyed it greatly. It seemed a very well produced book
with attractive photos. However there is a serious technical
error on p. 107.
The author states that burning green wood (half water) results
in half the log's energy being wasted (compared with dry wood).
In fact the figure is 5%.
A dry log loses about 8% in evaporating water. A wet log 13%.
My reference is Heating Your Home with Wood by
Also he doesn't mention using hearing protection in using a
sledgehammer and wedge. That generates very high impulse sounds
that are not picked up by the average sound level meter and
can damage the hearing.
