Hey guys... picked up these cool little speakers that have tone/volume controls on the front and individual tube amps inside. Seems like it could be a fun restoration, but I have never worked on tube amps and have no clue who might have produced these. All they say on the front is “stereo- hifi” and there is no other marking. The front screens seem professional but the tube amp has no board and is just wires running from place to place (the four wires coming out of that waxy cap caught my eye first). Speakers are mismatched as well (one has a green basket). Any info you could provide on what these might be and whether they are worth the restoration would be appreciated!
