Bias Probes for Valve amplifiers

[Terry]

You had a typo in your link - instead of a colon ":" you had a semi-colon ";", i.e. "https;", so the editor didn't convert it. I have now corrected that for you in the original post

The link still won't work, Nick, because there  is an apostrophe "'" in it that shouldn't be there (as discussed in later posts).

Did you try the link? If you look, you'd have seen that I had fixed that too...

I didn't try it because I could see the error on the screen but, as you insist:

This site can’t be reached www.that%27saudio.co.uk’s server IP address could not be found.

the %27 rers to the apostrophe in https://www.that'saudio.co.uk which is from post #3, which is the one you initially corrected.

I think the confusion is because the link has been repeated in other, later, posts.
