Features of the DA08SE

*Permalloy output transformer for highest energy coupling
  from the tube to the speaker
  (Permalloy output transformers are also made by some other
  manufacturers for over  US$1,000 a pair!)

*Z11 silicon steel laminates for both the AC transformer and the  filter choke
  (this is the material other tube manufacturers use for their output transformers)

*Sophisticated output impedance selector switch (in a 4-8-16 Ohm matrix
  for best speaker matching)

*All single-ended operation

*Mono block for infinite channel separation and devoted power supply per channel

*A combo Line Amp and Power Amp(Volume control on the front panel)

*Tubes: 6SN7 Input;  300B output .

* Slim chassis for compact 5-channel  side-by-side stack up.

*Power supply optimized for 117V /60Hz operation
  (Contact distributor for 240 V/50Hz units. Voltage not changeable)

*Output Power : 8 Watts
  Input Sensitivity: 200 mV   (There is no need to use any line amp)
  Input Impedance: 100K
