surfaces . Tweek I recently did all power cords as IEC connections
let all tube pins and applications dry for a hr then put in ,without question
everything sounds better .as long as the area isnot super hot where it will fry such as a super hot outputtube you are fine .
The stuff called tweek was the old Stabilant that was cut 8-1 it gave not much
protection . Stabilant 22A. Is cut with a 4-1 alcohol.
Used to drop in plugs to break any oxidation it evaporates fast .
i use on new gear put a thin coat pure 22 and plug in and wait an hr no problem.
the tubes sound for sure better detailed once clean and 22 applied. The $100
bottle comes with several applicators .and will last a Loong time.
i did my whole system best product I have found. Great for batteries in flashlights
even digital contacts.
