Amp repair and audio equipment electronics workshop

The Smash Room are pleased to offer you an in-house electronic and gear repair shop through Electronic Repairs UK.  Our Technician has over 25 years experience in electrical repairs and specialises in Guitar amp repair, valve and tube amp repair, general repairs to all music and audio electronics, Power amp and PA repair.  


We charge a standard bench diagnostic fee of £25.00 which is payable for all amplifiers even if the repair is considered uneconomical (this fee covers our time for opening and testing the amplifier). Our labour charge is £15.00 per hour, with replacement parts charged at a nominal cost. The first hour is to be paid upfront before diagnosis.

A quotation will be provided for any repairs that are required before any work is carried out, so you will know the exact costs. Many of our customers will provide us with a budget to work to, if the costs are then likely to exceed this budget we will contact them for approval. 

Our estimated turnaround time for a repair job is 7 days, but this lead time is solely dependent on the availability of spare parts.  If you require something repaired urgently please let us know and we will do our best to accomodate you.

Because of the high voltages circulating in valve amps, many of the components have a limited life (relative to transistor style amps). Many factors affect their lifespan including component quality, general amp build quality, design, and bias level. We will always upgrade the quality of components to ensure that the life of your amp is not compromised.


We can only estimate the cost of a repair once we’ve thoroughly inspected the item. We are therefore unable to quote based on a telephone conversation or an email  as there are so many components and variables to consider. We would always let you know if we believe it will not be economical and can easily cap repairs at your request.
