Here is the layout for the Cinemag PCB.
To the right, is the Cinemag running on a perfboard. Which tells me the wiring is correct, and that even a New England bloke can still P2P wire if he has too.

I will comment, listening to both IRF and R100 versions, The Cinemag itself is quite good, and feels very well constructed.

The tone between the IRF and and R100's is a bit different - without playing around with the Zen pots. yet. The IRF feels warmer and fleshy, with no loss on top or bottom. More notable than transformer changes.

Both respond really well to 4R load of CHR-70 speakers

I did not say that. They do sound different.
In my experience the SemiSouth can be toned to sound different ways, very clear and clean, very smooth and toned, etc.
Probably the Semisouth will excel with detail and soundstage -and zen pots will alter tone - but I told you guys not to take my thoughts too seriously. I am testing on speakers that are < $50 each for now. I am more after proof of concept than anything else, and to make sure the PCB's are viable for sale.

GB will start tomorrow and end on 12/30/12

Just need to get some final pricing on a connector set if you want some. (not sure if my selection will work, or if I can get cheaper ones.)

It's the black connector set for main board and the male pins for the daughter cards.
Also included will be some plastic standoffs and plastic screws to keep transformer from floating away, although mine appear to not move when held sideways.

Good news Mike
Will the GB be for entire kits including transformers and IRFs or just for PCBs?

Just for PCB's for now. Logistics for the transformers would be difficult.
They also would be 2-3 months out for some of them.
