Many thanks for the quick response gents.

Ben. I would be grateful to learn more about your dem tape.

WD40 addict Thanks for the link. The pics and description are exactly as I recall the demo back in 1957!

That elliptical speaker has an ancient heritage. My father was a radio enthusiast in the 1930's and 40's He was the proud owner of two ( second hand I think!) top of the range radios. Both used identical electronics. One was a Marconi console unit the other an HMV table Model 650 five-band radio.They had 10 valves on two chassis units, the smaller contained the power supply components plus a push pull output stage delivering about 10 watts max. ( KT63 o/p valves ) The speaker in each case was an elliptical unit of similar appearance to the Model 3034. In my fathers's sets the long axis of the speaker was horizontal and things did not run to tweeters on those days.
