Hi, I too have crt adaptors and cards, is there an interconnecting cable between the adaptors and tester. I have seen no reference to it. Norman

Hi Norman, yes there was a short interconnect cable about 3 ft long and mine is labelled
"CRT Adaptor B".
Octal plug and free socket, appears to be 1 to 1 and 2 to 2 etc connections.

Probably used to link the tester to the set with another suitable adaptor on the set end

Hi Robot, plenty of details of all the cards issued (and numbers not issued) in this section of the forum.
I believe GMB of this forum did most of the work. There was also a design published for a card punch, so you could manufacture your own cards. The material (approx. 1mm thick SRBP) is still available, but other alternative insulators have been suggested.

Hi Ed, Thanks for the info regarding the crt tests. The tester I have belonged to my old work place and I can't recall ever seeing a cable. Norman

Hi, Ed,

There's a pic and a brief write-up on the punch that Stan designed here.

Cheers,

Frank

Hi Frank, thanks for that, I think Ken was also looking for the data as well.

I have the gauge plate and silver steel for the punch, but it is still on the TUIT pile!

Gauge plate - serious stuff! I'm in the process of doing one, but it'll just be in MS - initially at least - with a 7mm silver steel punch.

My younger brother runs a small engineering business in Dalbeattie. He's had the CAD drawings for a punch jig drawn up, but I'm still waiting for him to make it.

How do you plan to do the punch? I'm wondering if a sinusoidal cutting edge similar to the old Q-Max chassis hole cutters (drawing attached) would give a cleaner hole, rather than just a brute-force flat-ended punch.

Cheers,

Frank

Hi Frank, yes the punch will be "Q max" style, it should cut SRBP easily and not need sharpening very often. It will then shear rather than punching, so should not tear the material.

Hello Everyone
I have asked for this thread to be reopened to ask how far this project is from completion. I scanned all the cards I have and converted them to PFD files over five years ago, but I am still missing 206 cards, please see attached “Missing Card List”. If the missing cards have already been converted to PDF files I would be interested in obtaining a copy of them to complete my own set. However if they have not been converted I wondered if members of the forum would be prepared to send copies of any of the missing cards on my list so that I can convert them.
I am more than willing to send PDF copies of my files to anyone who would need them, in fact I do not mind if the complete set is made available, either on the forum or by email. I could break the files into groups of 50 cards so that they would fit within the forum rules on PDF file size if that is permissible.
Please find attached a PDF copy of the Mullard numerical card list No.8. and a copy of Military Card Packs A, B and C.
Regards Stan.

See http://air-ministry.uk/mullard.htm for how far I got, which is close to all the known cards. But to confuse matters the odd card outside the documented range turned up which raised the question as to what they were for.

I have been meaning to try a final big push to get the last few as rumours keep circulating that some people have all the cards. But I have not managed to meet them yet!

Hello GMB
I have just checked through you missing card list and I noticed that some of the card numbers that I have listed as No Issue are not in your list. The numbers are as follows:-
775, 778, 781, 782, 808, 824, 830, 1080.
Have you found these cards and can you tell me what valves they are designed to test?
Also you have listed 893AB and 963AB; I have listed these numbers as No Issue.
It looks like I may need more than the 206 cards I thought were still missing.
Regards Stan.
