Like NEW, maybe 3 hours use. Variable Voltage for output power adjustment. This is a High Drive Box I used with my Stryker 955 and works very good, will do about 200+ RMS and 800 to 900 Peak. I used this as a driver for a GS35B tube amp. NO SSB or Biasing but can be added by BigDawg Amps.
The volt meter works fine, just would not show in image because of the phasing.
