Series Loop in 94?

[Russ]

Did Mesa make series loops in 94 on the Dual Rec? Here is an auction for #2202 that is claimed to be a '94 Dual that has a series loop. When did they change from series to parallel loops?

maybe they modded it or had it modded themselves.

By 94' it should have the RF-1F (10/93) board where the loop is the V4 that feeds the signal to the PI. It should be a parallel loop.

From the photos of the back, it looks like a serial loop...?

it's a serial loop. one of the last pics on there confirms it. the send/return knobs only have one arrow pointing to the send, instead of two arrows pointing to send and return.

So if the parallel loop began in the end of '93, how is this is a '94? Is this just an oddball?

When did the small logo stop?

When did they start with the IEC cords?

I am curious because I have a small logo attached power cord parallel loop Dual Rec with a serial number in the 3400 or 3700 range that I am buying. I can't remember if it was 347x or 374x. In any event, I guess it is one of the RF-1F and post 10/93 amps by Boogiebabies' description of the RF-1F. How many revisions were there? Did they stop at F and just start using the bigger logo and detach the power cord? I am assuming that the 3 channel amps are yet another revision of the board right?

they stopped at G. then came the 3channels. the first 500 end around D.
