It would appear you are back up and running, but if you want something cheap but usable, I can recommend the quintessentially English Nombrex battery-powered units.

They are cheap and reasonably cheerful - I restored one and used it for my first ever RF and IF alignment.

The signal purity is very average but after a little twiddling the scale is acceptably accurate (see attachment) and 100% usable for basic stuff.

I did 'upgrade' to an RF-1U, which I restored. And eventually succumbed to an IFR 2025.

Where the Nombrex is useful is that being battery powered (and cheap!) I can take it up the garden and couple it to the extreme ends of things like my long wire aerial.
