Audion Tube Amplifiers, Pre-Ampliers and Electronics


Sterling Stereo Mk1 EL34 Integrated PCB

Audion Sterling stereo integrated is built on a quality substrate pcb (printed circuit board) as with all our amps they are hand built. This pentode based EL34 stereo amp uses a small amount of feedback in the design. The chassis is black powder coated aluminum as is the transformer cover. The top plate and badge are mirror finished stainless steel.

The Sterling is a very under rated power amplifier, being musical straight out of the box. The Mk1 version is set at a low price to get people into the door, it's aimed at people who want to try a tube amplifier but who are on a tight budget. Sound wise however it ticks all the right boxes, sounding much better than its price suggests. 

Amplifier matching

This Sterling is suited for use with loudspeakers of 89db or better efficiency. Ideally matched with our range of Proton cables. The amp delivers 12 watts into 8 ohms. Our integrated model comes with 5 line level inputs and a straight thru tape output switched from the front panel.


Quality both inside and out

Having a volume control on the front and 5 stereo inputs on the rear means that a pre-amplifier is not necessary with this unit, unless a phono stage is needed . These amps are all auto biased. They come with Electro Harmonix EL34 tubes.

The Sterling is a good entry level printed circuit board Class A power amplifier at a very keen price point.  Integrated option (Standard stereo input is available)

Hand built Quality

The integrated Sterling is built with components sourced from Europe and the US. Where possible we avoid the use of any Chinese component. Our output transformers are wound in-house to our exacting standards and many of the components are either made by us or specifically for us. We use Electro Harmonix EL34 and Russian New old stock 6H1N as a driver and NOS Jan Philips 5687 tubes.
