UPDATE JULY 2025: We’re doing valve HiFi repairs again!
When we first started Keld Ampworks in 2012, we used to do quite a lot of valve HiFi repairs but after learning that Dave at Classic Valve Amps was a valve HiFi specialist I’ve been recommending that customers contact him for tube HiFi repairs so I can focus on the music industry. But now Dave from CVA has joined the Keld Ampworks team we’re able to draw on his considerable experience with these amps and so offer specialist Valve HiFi repairs in house again.
Valve HiFi repairs are charged at £100/hour. The minimum bench fee for a valve HiFi is £100.
