The 1593B, 1593C, 1594B are what you want. Similar models (the E versions) do not have voice coil taps (4, 8, 16 ohm) and some of these have been refitted with output transformers for 70/100 volt only operation so examine carefully.

With the right preamp such as the Alembic Fender clone or similar or a Champ with a dummy load and L pad off that, the sonics are astonishing. It works well with a wide variety of guitars but very especially with Rickenbackers and ES-335s.

These things are quite rugged and very reliable and can be repaired fairly easily by anyone who can read a schematic and use a scope. However, if you lose an output transformer you are in trouble.

They have a full output transformer just like a tube amp and load up just like one too.
Don’t attempt to modify the amp or to run a pre off the +24 vdc charger tap. There is some design in there that is not obvious. And don’t drop the power voltage to lower than 110 volts either. That will eventually cook the power transformer, many of which have thermal links in them which don’t reset. (I had one rewound, $200….)
