Most of us cannot afford a ready-built high power valve amplifier, but this kit changes all that, so that anyone can enjoy the superb 'valve sound'. 
To many people, the sound of valves cannot be surpassed either by bi-polar transistors or FETs. 
In developing this amplifier, special attention was paid to the housing. Indeed, it was decided not to hide the valves. Four EL34s are used in each channel to generate the high power output. Very high quality toroidal core ultra-linear output transformers are employed to provide outstanding sound quality. 
The kit is also available ready built, stock code VY10L. 
A cover is available and should be fitted before operation.
