[Milsurplus] Does anyone recognize this RAF Dyno.. answers

[J. Forster]

A couple of days ago, I asked: if anyone recognized the RAF Dyno on eBay, item
number 6515513150.

Here are part of the answers I received from George Bichard::

Yes, it looks exactly like a Power Unit Type 319 (used for beam
approach equipment). The specification matches this exactly too.


I then asked about the valve:


Yes, its a 120V regulator. This is for the 120V stabilized output which is
additional to the main 200V HT output and the stabilized LT output.
I have the full details, circuits, everything. I could send you a copy of
some of it if you like.

By the way, in case you fancied buying it I should warn you that it's only
half a thing.  For some strange reason, the voltage regulator unit was external
to the
power unit on this model.  It won't work at all without the regulator!
It needs a regulator Type 12.

If you are interested in this kind of thing in general I know a man who
would sell you a CD of the entire manual of these objects for about £12.


Thanks very much. I'm not interested in bidding, just curious. Most of the RAF
kit is beyond my means.
