Hi Ron,

You're quite correct I was just reading it incorrectly. Now I've had mine apart I see what was meant. Here's the inside of mine and proof they were using Vishay MKT1813 in the 1940s..... There was a reason I didn't finish this a few years ago, possibly pondering what to do with the rectifier. I don't recall. I do note the original soldering isn't great.
