Re: HMV 1804 Television.
Circuit diagrams of the sync separator stages in the HMV 1804 and 1805/6.
The interlace filter circuit I've opted for is the one shown in the first attachment. The sync clipper as used in the 1805 will be employed in my 1804. Only two additional components are required, R48 (47Kohms) and C36 8microfarads) The third attachment shows the circuit of the two diode interlace filter in the Pilot CV34.
