Design Note :
This design just sounded so good and perfect sized - many wants to have compacted sized but full Class A tube experience and build. And this is it!
The 6V6 is so euphonic, musical, and offers good tube sound.
With over 8 watts on the tap - it beats most 300B SET amps on the market!
The 6V6 tube easily is one of our top 5 favourite power tubes - it’s inner heat is relatively low in comparison to other tubes - which makes them more reliable and durable than other kind of tubes. The variety and prices is also one of the best today too, so it’s hard not to like this tube.
