Ed,
Thanks for that data.
On this thread:
https://www.vintage-radio.net/forum/...ad.php?t=37396
he used 0.22mm wire. It might be that this refers to the wire without the enamel.
It looks like the bulk of the tuning capacity is across pin 1 & 3 , the 470pF, so probably this could be adjusted to allow for different overall self capacitance or slightly different insulation etc of a rewound transformer.
Can I ask Ed, if you had this set with a failed Metrosil on pin 5, what component/s would you replace it with as an electrical equivalent ?
Hugo.
