EML 300B mesh driven by c3g.
Heaters supplied by a Coleman board.
Interstage coupled (a really well sounding Tribute on amorphe core).
A lot of Tamura irons. Including the famous F-7003 (5K). A little pain for my wallet but a plesure for eys and ears.
Case with frame of walnut wood matching a Corian top.
Dovetails joints on edges.
Professional Neutrik (sepeakon, powercon and rca) connectors which I found more reliable and good quality made for a fraction of the price of "audiophiles" ones.
Gain enough to be driven directly by the DAC (Buffalo I).

Default Tamura F-7003 & 845

Beautiful amp Popla.

An interesting coincidence, this is my 845 SE 10W amp, 2 stage design using Tamura F-7003. Input tube is C3GS (nude) in pentode mode (plenty of gain), capacitor coupled to 845 tube. Beautiful sound when mated to my Stacked Quad/RTR tweeter, now it power my Tad2001 horn.

Wish we can compare the two amps sound!!!!

The tube I thank is a WE437 but is a C3G without shield.
