What I cost
Restoration of vintage and valuable guitar, bass and jukebox valve amps will likely be £200-£600 labour plus major parts. Some transistor amps are worth restoring, eg the Roland Jazz Chorus, and old Acoustic bass amps, but most are not.
Valve hifi restorations usually about the same or more. I don’t do transistor hifi, you need a specialist with relationships with the manufacturers for that.
Harmonica conversions about £100.
AMI jukebox amps £200 – £600
My labour charge is £30 an hour, or £200 a day. This includes minor parts. The above estimates are based on these labour charges. This is the same as before, so established customers won’t notice a change in their repair costs.
I can’t estimate costs with having the amp on the bench. Even then it’s only a ball-park guess as in a restoration you don’t know what is going to show up as a fault next. But I want to remain reasonable, economical and predictable and I won’t ever charge you more than the amp is worth however long it takes. In general I won’t go over my maximum estimate unless there is a very good reason, I will put in extra hours to achieve this, and I will consult with you about any extra costs.
