Default Re: Refixing loose valve bases

I had a KT66 with a loose base. I waited for a sunny day, went outside and poured a little meths into the base (with valve upright). Then left it for a few hours.

On my return the valve was solidly re-bonded to the base!

How it works: The meths dissolves the shellac, but then slowly evaporates leaving the shellac bonded in its new location.
