Arley,
In general, this holds true for most of the earlier plans. Estes began removing this information in stages, first by only giving those 5- and 6-digit part numbers without actually telling anyone what they were, and eventually removing all information about the tubes in more recent plans.
The kits that Bill has listed in this thread are a good mix of these examples. The earliest plans do have the full descriptions of the tubes, while some of the 1900-series kits only have the digits. Many of the later 2000- and 2100-series plans have no part designation at all.
Given their trend at the same time of eliminating (or drastically reducing) the available parts, this marks their shift toward the impulse buyer and away from the hobbyist-builder-designer types that were their core customers. |
