I finished the restoration of the hybrid set 2 weeks ago. It's now possible to directly compare the tube version with the hybrid.
Both sets work surprisingly good, espcially the sound quality of the tube set is impressive, even though the output tube is not really strong to save battery capacity.
To the restoration: Both sets usually have massive problems with a built in rechargable battery which leaks out it's acid that causes a lot of corrosion usually. Also the handle is usually broken as well as the antenna.
Finding a good example can be time consuming and expensive too also these radios are quite wanted and sell fast usually.
