Included in the Mt. Rushmore of classic British amps is the Hiwatt Custom 50w. This amp is badged as a DR-505, which is simply a Canadian designation for the DR-504. We can confirmed this amp has been internally jumped from the factory, which they did with some of the imports. This means the "Normal" input will function normally, but the Brilliant channel will pass through the gain stage of the normal side as well, elevating the gain. Here is some literature from Hiwatt about it, for those curious:

Other than this CA factory change, the amp is all original, aside from an added bias trimmer—a useful upgrade for easy tube swaps. It shows moderate signs of wear, mostly light scuffing along the edges, but overall it still presents very well. It also comes with a heavy duty road case!
It should be noted that the Normal pot is a bit scratching during adjustment This may not bother most players, and due to the all original nature of the amp we left it in. We are happy to swap it out, upon the buyer's request. Also keep in mind that despite being fully functional this amp has all of it's original electrolytic capacitors. Should someone need prolonged or gigging use then servicing would be advised (cap job, etc).
