I have a very nice pair of a60s series 1 except one of the tweeter is balky. Nowadays it doesn't work more than it does. The cabinet wiring is fine as I've switched the good and bad tweets from cab to cab and it is the tweeter. I have a parts cabinet series 2, but the tweeter is different. Do I swap the working series 2 tweeter into the series 1 cab or try to find a working replacement? If I swap will I kill the cabinet as it would entail a drill and hole saw? Recommendations?
