SURFING MUSIC SOUND-WAVES

I was disappointed of the 300B sonic and hope the DHT2A3 as a better alternative 

This amp proved to meet my expectations , and became my favorite combined with the recently completed DHT26 as pre-stage.  Despite claims that it needed  sensitive speakers with > than 95Db , it factly easily drives my old Proac R1S bookshelves ( 87Db sensitivity)

NOTE :

2A3 NOS tubes are now very expensive.

You need a user-choice  filament  supply module, and  socket converters  to switch between the tubes ( 2A3 , 6A3 , 6B4G ) 

 Go to page << Tips and Tricks >> for building your own tube socket converters.
