Whammerdyne Series (2) “Damn Great Amp” (DGA2)

 

Power Docking Base (an industry first)

Base power supply is “docked” to “amplifier module”, 100% total isolation of amplifier and power supply (6) fully regulated DC ultra-low noise supplies in the power base enclosure.

Amplifier module (DGA2)

  • Alps “Blue Velvet” stereo input volume control, direct coupled to gain stage. With the DGA2 we now hand select for matched linear tracking with both channels to ½ Db
  • Two sources input, selectable (Input 1 and Input 2)
  • 6DJ8/6922 input gain/drive tube DC coupled by our unique Z-Direct coupling circuit to the output stage. (TRUE DC stage coupled, no capacitors in the signal path) We use a hand computer graded and matched** section Old Stock tubes
  • Output tubes 2A3 type grid biased and run on regulated DC supplies and DC filaments. Output transformers utilized are gapped for 60-70ma standing dc current and of extended wideband design. 4 and 8 Ohm speaker output terminals. We use a hand computer graded and matched** section Old Stock tubes
  • EZ bias system utilizing analog panel meter with indicated “set” point bias takes only a few minutes and only needs adjustment as tubes age. Built in tube condition tester
  • Same circuit topology as DGA1, except we hand match and grade many of the very critical parts, improving channel balance and overall harmonic distortion and gain a bit of power.
  • Measured specifications:
  • Three and ½ watts per channel, peak power 6.0 watts per channel
  • Wideband hum and noise less than 300 microvolts. (both channels)
  • Bandwidth +/- 1 Db 18 Hz –35 KHz +/- 3 Db 14 Hz-55 KHz 2nd harmonic down 65 Db at rated power
  • 115 watts, line at 117 volts AC 60 Hz.
  • Warranty 5 years amplifier and power base, 90 days tubes
  • Provided with Old Stock issue 2A3 tubes and 6DJ8 (Matched pairs and matched section NOS upgrades available) ** Hand selected tubes are from our vast inventory of New Old stock tubes and Old stock tubes. Precision matched and graded on an Amplitrex AT-1000 computer test unit (We provide printed test results and matching results with the amplifier)
