Hi Fred, I seem to have some difficulty getting Acapella to answer their emails :) I was wondering if you can answer my questions. My TW-1S is almost 10 years old this year. I would like to know:
- how often the electrodes need to be replaced
- whether there is anything else in the tweeter that needs service
- how long the PL519's last (have you noticed that they are NEVER turned off!)
... would you happen to know?
