| Blanka:
Use a 7809 voltage regulator with a heatsink. It can handle 1 or 1.5 ampere, depending on the model. http://nl.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=5164812 Oops: READ, it says AC BUT, 9 V AC is often regulated to 12V DC. Amplifiers always run on DC. Make a picture of the circuitboard. |
