Works and sounds great! The amplifier is the early grey chassis model and both it and the pre-amp are in nice cosmetic shape as the pictures show too. Amplifier is rated at 20 watts mono and uses 6SN7GT driver tubes and 5881 output tubes. (With a 5V4G rectifier). Has 4, 8 and 16 ohm output.
The preamplifier has a pair of 12AX7's and a 12AU7.
Sold as the pair only and come just as shown in the pictures.
