More evidence that the modifications were performed by a Pye engineer. The original frame blocking oscillator transformer had been replaced with a Pye component, the same one that is used in the D16. Now that good news for me because I been on the lookout for that particular part for years. After the connections have been traced out the transformer can be fitted into my D16. A normal two winding blocking transformer can be fitted in the HMV.
The interlace filter unit has been removed and the circuit will be returned to the original HMV circuit. A standard Plessey blocking oscillator transformer can be wired in.
Further examination of the modified RF and IF circuits shows that the work had been carried out in a competent manner.
