Why The Ampico B May Not Play Ampico A Rolls Well
By John A. Tuttle

Hi All, Craig Brougher has written another interesting and
informative article in which he examines the subject of 'why an Ampico
B might not play an Ampico A roll well'.  Since this has been a topic
of much discussion, dating back to the days before the Ampico B went
into production, Craig includes such things as a conversation between
Dr. Hickman and Nelson Barden, and a thorough analysis of that exchange.

Craig also explains the fundamental operating characteristics of the
Ampico A and B systems in a manner which makes it easier to understand
the flaw in the basic complaint, i.e., that the 'B' doesn't play 'A'
rolls well.

In the closing pages of the article, Craig exposes what he's found
to be a common problem in the last "half-dozen or so Ampico B's (he's)
received to re-rebuild".  Then he goes on to explain exactly why this
problem makes it 'seem' that the 'B' isn't capable of playing 'A' rolls
well.  He also touches on a few other relatively common problems he's
found in rebuilt units which adversely effect the performance of the
'B' system.

This article reminded me of something my 93-year old mentor taught me
when I was working as an apprentice at Tusting Piano Co in the early
1970's.  Simply put, he said, "John, don't be fooled by appearances."
Wise words on so many levels.  You're sure to enjoy and be enlightened
by this article.  See
