I touched it with the iron while soldering the pots to the board. Is this burned and unusable?

This reminds me of an old, old happening. Back when I was an engineerling, engineering departments still had department secretaries and no one but secretaries knew how to type. Our department secretary was on good terms with all of us and a respected member of the department.

But we all cracked up the day she walked into the lab and asked "hey guys, what color is a capacitor?"

Of course, the appearance of a cap can only be the crudest indicator of its internal condition. Burned to shreds, easy. A litttle hot looking? Hard to say.

Since we don't directly sense electrical matters, we're forced to use -meters- to measure whether the internal very very high resistance has broken down, or if it's charge storage has been um, impeded.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

It probably just became more "vintage" sounding.   :icon_razz:

Point taken RG, I don't have any experience with these things - lots of learning opportunities.
