Supro Bantam amp questions, thanks.

[bigdaddy]

I know someone with an old Supro Bantam with the 50L6 power tube. He wants a new speaker and doesn't know the impedance, anybody know?

Also I told him to bring it to an amp tech and have a 1:1 iso tranny put it so he doesn't get killed especially if he blows harp through it. Am I correct about that?

Thanks.

4 ohms (not critical).

Yes.
