Block logo/RS Deluxe JTM45 with factory impedance switch!

Check out this thread at the Les Paul Forum:

It shows a fantastic, one previous owner, early '65 block logo JTM45 with Clapton knobs and RS Deluxe output transformer...with a factory original impedance switch!!! As those of us who have built repros of these amps with the RS Deluxe type OT will know, it is a PITA to get multi impedance selections on these OTs due to their unique secondaries setup with turrets. But judging from the way this switch is set up, it is not so complicated after all! And it even preserves the feedback at 16 ohm, which is the only way these amps sound "right" IMHO.

When you think you've seen it all... :clap:

amazing find, although it is more like a 4/16 ohms switch
