Well saved! They are quite similar but I would need to look at the circuits, there will be lots of detail differences. The vidicon head BD896 had a smaller power requirment than The I.O. also the tube suppies were simpler than the I.O. I ll try to find what the differences are.

I have a MkIV vidicon head, but no CCU or PSU so if you could do some pictures and send them to me I would be able to add them to the camera museum.

regards

Brian

I have had a look at what handbooks I have in the museums library, the CCUs look very similar having most of the modules with the same number. Sheet two of the CCU drawings, the plugs and sockets on the rear are different, the vidicon one has fewer connectors.

I do not have a drawing for the vidicon PSU, it is in Marconi book T.3975 (hint) but looking at the PSU for the I.O. camera it is mainly the +250volt supply which could be the same, also in the I.O. PSU are the focus, talk-back, and Iris amplifier, these are likely to be missing or different. I have a vague memory that the space is there and they are just not fitted.

So I do think there is a lot of items in common. I can also confirm that the vidicon control panel is the same size and style as the I.O. control panel, but with fewer controls. It is a very attractive panel with black perspex and the lettering is illuminated by bulbs set into the perspex. I do have a control panel for my Mk IV, must do photos of it sometime.

If you are able to do some good high res photos suitable for inclusion in the museum I would be pleased.

Mine is a full channel viable with all the parts needed, except time!

I know that two of the others are complete, most people say I've got a MkIV and don't go into detail about CCUs etc.

This thread seem,s very popular (3,190 Views).It looks like the final Count for Complete Chains as of (05-30-2012)


UK=5 Chains 4 Known of. Heads 5 (I know golden-agetv.co.uk have 6 ) 1 Chain from NZ

NZ=5 CHAINS 4 HEADS Known to be about (Mine Ex BBC (A/B) and NZBC (J) suffix
AUS= Nearly 1 Chain 2 Heads
Brazil =1
USA/Canada =1 Chain 6 Heads

(That means that their are Only 11 Complete Chains remaining out of 916 made.)
If you have more please post !

Gibraltar=1 Looks like 1 more Head according to this Photo http://www.facebook.com/photo.php?fb...7768249&type=3

I have recieved One of the Chains in the NZ Count (It Pays to Advertise ) all I wanted was a Door(Still wanted) .This Camera is a late Model J (625 Only) and is Complete (In time I will Soak test her).
What are the Known Age Faults to look for please (Apart from Caps & Resistors Valves).
