Grateful for the copy of the manual, which also has schematics.

Scanned at 600dpi and uploaded to The achive.org and BAMA,
though the latter not shown on the site as yet. Tried to upload to
KO4bb, but can't get their app or plain tfp to work at all. The
files are of interest. What they managed to achieve in 1962, using
some of the very first Fairchild planar uhf transistors, the 2N708.

The one here was originally sold the the UK RAE (Royal Aircraft
Establishment) and at the list price, only government depts or
well resourced companies would have had the funds.

Serious historical interest here anyway, and will get it working if
possible. Scanned files are here:
