Theo Argiriadis designs, builds, repairs, and restores analogue electronic audio equipment especially amplifiers. He has over thirty years experience of analogue electronics and is qualified with a Bsc (Hons) in electronics & communications specialising in electro acoustics.

Theo’s objectives in diagnosis and repair are performance and long-term reliability. He is a specialist in the restoration of vintage guitar and hifi amplifiers including the complete rebuilding of amps, and modification.

Boutique guitar & bass amps are designed and hand built in the workshop - one of which is the unique and innovative AAE single ended range. Also, unique AAE preamps, distortion, spring reverb and equalizer units for studio, live or home use. Custom design of hifi & preamps, phono, line and output stages.

Argiriadis Analogue Electronics is an electronic and engineering workshop, not a music or components shop which means all charges go to labour and parts. Theo does not make money on selling parts. All work undertaken is carried out personally by Theo, therefore you will speak to the person who will work on your equipment. Equipment is usually looked at on the same or next day. Amplifiers can be tested at full power in the workshop, especially after the repair.

The main issues that affect repair are design faults, long term use and/or abuse and equipment which has been quickly and badly repaired or modified. Often faults and diagnosis are straightforward and minimum repair fee labour charges apply. However, sometimes amplifier problems are complicated due to intermittent and knock on effect problems. Therefore thinking time is needed, especially with design faults where modification might be necessary. Old used amps may require restoration work. A detailed explanation of what Theo does is in the restoration/repair page. All equipment is guaranteed and work includes service reports if required. It is a requirement that before giving an estimate Theo must see inside the amp.

Custom built charges are discussed per unit and are flexible and reasonable. When developing a new design the sound can be tested throughout the process by the customer.
