Behold the beauty of this 1977 Hiwatt Custom 100. One of the loudest lushest amps ever produced. This is a DR105 model, which is the Canadian version of the DR103 - it was modified specifically for the Canadian Market, in order to meet stricter CSA electrical requirements, other than this one change they were identical to the DR103, specifically the 2-input versions from the tail end of the 70s - Complete with Partridge transformers, mustard caps, and immaculate wiring. 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 thus increasing the gain slightly when using the Bright channel. This amp is in great shape and sounds top notch. Brand new set of JJ power tubes just installed.


There have been a few mods:

There has been an effects loop added

The handle has been replaced

2 output tube socket were replaced - this isn't uncommon and wouldn't affect the sound of the amp at all.
