Table of Known First Generation Sets

 

If you would like to add sets or further data to the table then please write to me via the Feedback page.

Some early chassis assemblies do not have serial numbers but most have a stamped 3 or 4 digit number that probably corresponds to the sequence of manufacture. Many of these sets were returned to the factory for refurbishment after the prolonged inactivity during the war and I think some swapping of chassis assemblies took place resulting in some newer sets being fitted with assemblies reworked from older sets. (You may also see 5 digit silk screened numbers. These are simply part numbers.)

The 702, 901 and 703 share the same Timebase chassis and the number location is highlighted in red below. Whilst the 900 has essentially the same schematic it uses a rectangular chassis and the number is also near to the connector tags.

 

 

 

The Sound chassis number is normally located at the RF end but earlier units may have it near the RF input cable entry and may be concealed by the screening metalwork.

 

The TRF chassis number is located near to the output connectors.

 

The 901/702/703 Power Supply number is located in front of the HT smoothing capacitors           The 900/902/705/701 is located to the right of the connector panel
