Very interesting... I had no idea that there were magnetic phono
cartridges as early as 1951. I was under the impression that they
weren't commercially available until the 60s.

Much earlier than that - the first electronic gramophones had magnetic
cartridges. Say in the '20s. Ceramic is a later invention.

Yes it was a surprise to me, It must be genuine because the 1951 service
sheet mentions it. I'm surprised at the strength of the magnets, the steel
rule in some of the pics had to be half an inch from the bakelite hosing or
it grabbed the rule. Anyone ideas how to measure the strength of the magnet,
hover a steel rule over scale balance and plastic spacers ?

It was 67GBP 4s, in 1951 which translates to 1,364 GBP in year 2000, via

....just a thought, you may want to change those paper/wax capacitors
(think that's what they are) in the amp while you're in there!
