Default Re: RA17 Rebuild and mod state query

Hello Rob,

thanks for the information. Yes, I can confirm my RA17 is ex GCHQ, it belonged to the father of the chap I brought it off who worked there. Also confirmed with some documentation.

I've just checked R84 in the calibrator and it has been changed to 22k, so that fits.

It looks as if the original paper capacitors have all been replaced in the past, however I'm replacing them all again along with the resistors for long term reliability.

That's why I was hoping to get a definitive list of all the components I want to replace, so I could order them in one go.
