Tube Amp Doctor

Tube Amp Doctor, commonly abbreviated to TAD, is a German brand specialising in valves and components for valve amplifiers. Its range includes replacement power valves, spring reverb tanks and parts used in amplifier maintenance and construction.

The brand is known for selected and matched valves, including 6V6, EL84, 6L6 and EL34 types. Products are offered in configurations such as matched pairs and quartets, while its Redbase range includes several power-valve models. Its amplifier components also include Type-4 and Type-8 spring reverb tanks.

The current MyGear selection comprises 12 products in stock at partner retailers, priced from €40 to €158. This selection places the brand in the specialist replacement-parts market rather than the complete-amplifier category, covering reverb tanks and valve sets for servicing and maintaining compatible equipment.
