i love this type of point to point construction , where the back of the valve socket extends backwards and tags are riveted to that tube up the length of it so as build that particular valve stage right on the valves base. beautiful and simple. at their age these amps have plenty of leaky hi voltage caps. they work and sound good .. but you can tell they are on the edge of crapping out completely. the leaky coupling caps cause the controls to be extra noisey , also can cause the amp stage plate resistors to burn out , and usually false bias the following stages to the point of almost cut off. the power supply sags and the whole thing goes about 25%. i’m using french made solen brand parts to repair these amps. ive had only good experience with them. they dont leak d.c at all and are not physically oversized.
