This small (53/8" x 31/4") booklet contains data sheets for 55
valves,
including 2, 4, and 6 volt battery valves, full wave rectifiers and
directly heated output and indirectly heated, mains valves. The
inclusion of pentode valves means that it was produced after 1928 and
the illustration of the valves with top marking and logos confirms
this. The number of valves that had become obsolescent by the time of
the printing of the 1933-4 Master Valve Guide or had been removed
altogether make me think it was probably issued some time in the period
from 1929-31. Each sheet has maximum and/or preferred operating
conditions and a graph of some characteristic.
This is the index page for pdf page scans
of this databook. It is arranged in three sections:
- Pages containing full descriptions of individual valves are
immediately below.
- Other pages with various interesting
articles and tables, including lists and brief characteristics of
obsolescent valves "available for revalving".
This section also contains a long list of recommended valves for a
multitude of 20s and 30s sets from many manufacturers.
- A section with pages arranged by page number
and
several indices.
