Default Re: HMV 1804 Television.

Hi Oliver,
I don't think the EF54 was ever employed in any TV receiver, it certainly caught me out. I just assumed the RF amplifier valves were the common EF50. The EF54s used in this set are ex-services types, a VR136 and the other has finally been determined as a CV1136. The mixer is another ex-services type, a VR91 = EF50.
It's likely the chassis was in good condition at the time it taken out use possibly sometime in the mid 1950s. The underside of the chassis is in excellent condition.

DFWB.
