The catalogue starts with a section on 'germanium signal diodes' comprising four series:
The images show an HG1005 and an HG5009 used on circuit cards from a LEO III computer.
A number of the above are type-approved in the UK military CV series. The ones in the 1963 Register are:
|CV9401 = HG1001||CV7041 = HG1005||CV10032 = HG1005||CV7130 = HG1006|
|CV10691 = HG1007||CV9414 = HG1010||CV8636 = HG1012||CV9725 = HG1086|
|CV10825 = HG1087||CV7127 = HG5004||CV10089 = HG5004||CV10227 = HG5008|
|CV9694 = HG5009||CV9176 = HG5081||CV10226 = HG5085|
I think these CV7127 are Hughes-made, although they do not bear any manufacturer or date code. CV7127 has prototypes HD2595, 85P1, AAY12, AAZ17, and HG5004.
Next follows a section on 'silicon switching diodes' comprising two series:
Two of the planar epitaxial diodes are type-approved in the UK military CV series.
Then a section covers 'Zener diodes' comprising two series:
Then a number of sections on other diodes that I shall not list in detail:
Then we come to transistors. There are five sections of normal transistors, nearly all 2N types. I list only the non-2N ones:
There are also two sections on silicon 'glass ambient' transistors: GAT1000 - GAT1003 and GAT2000 - GAT2002.
A number of the above transistors are type-approved in the UK military CV series. The only ones in the 1963 Register are:
- CV10066 = HT100
- CV7417 = HT101
