Elpelotero said:So on the middle shelf, from left to right there's 4 amps. A clean silver amp, 2 rusted, and a black. You're saying the silver one is a recto? The one with the 5ar4 also seems like it could be recto.
That picture is worth a thousand words. Tell us more about it.

IV on the right, Recto on the left

If you let the smoke out, they stop working.
Interesting, since I have a B with an attached cord. I haven't had a chance to a/b it with another M4...igfraso said:I was told there are 3 versions of Mark IV's: the A, the early B and the regular B, and that the best sounding are the early B's which are the ones that don't have the detachable power cord.
