This is one of the early Hiwatt DR103 amps built in 1970. It has a power of 100 watts
using 4 ECC83 and 4 EL34 tubes. The total peak power is approximately 250 watts. The amp has two
channels one named normal, one named brilliant and a 4 band equalizer.
Hiwatt's all purpose amps can be used for either guitar, keyboard or bass amplification.
This amp was tuned with an additional preamp stage using a fifth ECC83 tube. It is therefore capable of producing a high gain sound as an alternative to the original Hiwatt crunch. Listen to the sound examples.
If you look closely at the large picture of the front-face you can see that the original Hiwatt logo got lost and was replaced by a laser printout.
