Help me to ID these tube amps

[anti-doom]

I just found these 3 big tube amps at local Goodwill store for $20 but I do not know what they are. Please help me to ID them. Do they has good selling value on Ebay?

Some info:

One amp has Dynaco A431 transformer on it.

The biggest one has mark "Jefferson electric" on two big cans.

Including these amp are some tubes and some weird wires that I have not seen them before.

Thanks.

No idea what they are but the transformers are probably worth something.

The Dynaco A-431 transformer is worth MUCH more than you paid...

Looks home-brew to me. Built a long time ago by someone with pretty high standards and budget for the day.

the one with the dynaco transformer is part of a 2 chassis design(the dynaco one being the amplifier with the output transformer and one of the other chassis being the power supply. the weird wires you point out are to connect the dynaco to the power supply)

Do they has good selling value on Ebay?

depends on the numbers on all the transformers and if your will ing to take them aopart and sell.also this is the wrong forum to ask value in .all questions like that have their own forum called dollrs and sense.
