A Private Collection of Early Electronic Equipment
and Unique Electronic Components
Anecdotes and Insights into Electronic History
1850 to 1950
Based on the collection of the
late Rudolph Mangold
Originally it was our goal to keep the collection
intact and present it to the public locally. Sadly we
are ceasing efforts in this area due to health issues of
the primaries involved. Because of our inability to find
a proper local venue we are now placing the entire
collection, as a whole, up for sale. The value was
incredibly difficult to estimate. There are many items
without precedent as far as establishing value is
concerned. In addition, the historical continuity of the
collection must be seen to be appreciated. It is truly a
"Museum in a Box". The inflation adjusted number of Mr.
Mangold's valuation before his passing is approximately
That being said, we will consider all serious offers.
Any particularly low offers need to be accompanied by
supporting explanations (a "reality check") to allow us

examined by those individuals who desire to see the

The original technical notes are German and
English mixed. The translation of complex

German half of the site was driven by the amount
of notes in that language. I wished to place these
notes (Tube Museum, Tube Technical notes, and
Basel Amateur Radio History) up for public
viewing. As this site is built some pages will be
displayed as generated by the Babylon and Systran Translators. All
pages will eventually be reviewed and updated but
this is a slow process. Patience is therefore
required to read some pages.
There is a dictionary that I will be contributing
specific words I come across to. It can be
