Bias Probes for Valve amplifiers

[Nick]

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...
