We have got some new valve technology coming and most of these are 21st century designs ( yes new technology) in audio valves !!! It is rare to see innovation in audio valve technology and JJ Electronics are doing it.
This new valve technology are valves that are designed to give you the ability to have new colours of sound from your amp just with a valve change. No component changes needed. Check back in about a week or follow us on twitter at @vintageampfix and you will know when our update is ready.
We should be all set to update you by the end of July , 2015 when we have the products in stock. I hope it may be sooner as the products are in transit from JJ Electronic in Slovakia to us right now.
