Hi, just signed up and have a question about mains hum on my Bugera v5. I have read through the massive Bugera club thread and am in the process of trying the recommended bright mods and valve / tube swaps. My amp has the often mentioned mains hum, most noticeable on the 5w setting and least on the 0.1w setting. Although this has been mentioned by several people I have not seen anyone suggest a remedy ? I came across the Rat mod site where they say it can be fixed but of course they don't give any further information. Considering the wealth of excellent info on tweeking the sound there must be something somewhere about curing the hum ? Any thoughts gratefully received. Thanks Terry.
