Does anyone know if there are any profiles available of the Hiwatt DR105? The DR105 was a version of the DR103 that was built specifically for sale in Canada in the late 70s -- the DR103 was switchable between 115V (North America) and 230V (British) power, but Canadian regulations required that this feature be removed and the amp be hard-wired for 115V. So Hiwatt built the DR105 just for Canada, and other than this one change, it was identical to the DR103 (specifically, the 2-input version from the tail end of the 70s). However, although they were identical to the DR103 when they left the factor, the Canadian distributor for Hiwatt modified every amp that came in by wiring the output of the bright channel into the input of the normal channel.
I have been looking for a model of this sound for a while now; I strongly believe that Alex Lifeson of Rush used this amp primarily on the albums Hemipheres and Permanent Waves. Does anyone know of an available profile of one of these amps?
