Marconi TF995A/5 signal gen

[ppppenguin]

Just acquired one of these. Looks like a useful instrument.

Downloaded a manual here: http://www.ko4bb.com/manuals/download.ph..._10414.pdf though the component location pictures aren't the best scans in the world.

Any thoughts before I apply power?

In the same batch of stuff is a RCS counter type 401 which may get its own thread. Lovely glowing nixie tubes.
