Outline Notes
1. Anode temperature measured at this point. Paint should be removed from this point before temperature
measurement is made.
2. Reference plane B passes through the centres of the two holes of the mounting plate as shown and is
perpendicular to reference plane A.
3. Reference plane C intersects plane B at the centre of the mounting plate hole as shown and is mutually
perpendicular to reference planes A and B.
4. With surface A resting on a flat surface plate, a feeler gauge 0.51 mm thick and 3.18 mm wide will not
enter more than 3.18 mm at any point.
5. The axis of the heater lead protector will be within 58 of a normal to reference plane C.
6. Surface A and interior surfaces of the waveguide will be plated with 1.55 mg/cm2 of gold or 4.65 mg/cm2
of silver, but will not be plated if the parts are made of monel or equivalent corrosion resistant materials.
All other metal surfaces will be painted with heat resistant paint or otherwise treated to prevent corrosion.
7. The clearance between the inside surface of the protector and the 9.53 mm diameter cylindrical surface
of the standard single contact miniature bayonet lamp base (B.S.52 (1952) Type BA9s/14)
will not be less than 3.18 mm.
8. The position of the waveguide hole is not specified on this drawing since tubes are tested and used with
coupler UG-40B/U (NATO S.N. 5985-99-083-0051).
9. The centre of this hole will lie within 0.102 mm of reference plane C.
10. These holes will lie within 0.127 mm of the indicated centres. A cylinder of 8.38 mm diameter and centred
on these holes will clear the side of the magnet.
11. Recommended direction of air flow.
12. The north seeking pole of the magnet will be adjacent to the cathode sidearm.

11. Length of flying leads measured from the centre line of the anode block.3
