I have a Hotrod Deluxe, about 3 years old. Recently it has started to make a horrible intermittent whining whistling noise for about 5 minutes when I switch the amp on. Then the noise goes. Any ideas on what this could be? Thanks

Bad tube or capacitor. Make sure you rule out the guitar and cable by swapping them out. Bypass all effects and plug straight into the amp. Try also another location as amps tend to pick noise from their environment.

Unless you have spare tubes or want to buy some as spares you will have to take it to someone to check out the amp anyway. If its in warranty try that first.

Can be dangerous opening up the amp. Best left to a tech.
