Just a tip if anyone wants nuvistors: look out for Tektronix 1A1 or dead 453’s with serial numbers less than 20,000. They have two socketed nuvistors in the front end and a whole world of reusable parts. If they are beyond repair it makes sense to recycle accordingly.

I’m ashamed to say I had six dismantled 1A1’s I got in an eBay auction for £5 which were stuffed with nuvistors and sockets. They went back on eBay thinking I’d never have a use for them. Went for £75. Nearly fell off my perch!
