Thanks to Mike LaFevre, Xavier Cortes, Anthony Cirella (of Handmade Electronics) and my late father-in-law, I have completed the world's first Mexico Series (copper) passive pre!
A while back Mike posted that he had a pair of new Mexico Series High Nickel B7 10k:10k transformers with copper windings available. He also confirmed that the designation "Mexico Series" was due to Xavier ordering a pair with silver primaries and secondaries. After some correspondence I ordered the copper pair, and then, having decided my conscience (budget) wouldn't allow the purchase of a P&G 10k pot to match, had Mike send me an Alps Blue Velvet instead. I ordered some Cardas jacks and Kimber wire from Handmade Electronics, and picked out an old cigar box of late father-in-law's which I had set aside for just such an occasion.
The eagle-eyed among you will see evidence of my ham-handed construction abilities - in my efforts to avoid having too long wires poking around everywhere, I made some too short, and had to extend them!
The volume knob is just a temporary Radio Shack one - I have some old chickenhead knobs around here somewhere, but think I'm going to try to find a wooden knob to finish it off.
Anyway, I checked and it works fine! I will soon be running it into my old Bottlehead Afterglow amps, which feature Magnequest TFA-204 output transformers! And it reminded me that I have the Magnequest bike jersey from way back!
Many thanks to Magnequest and all others who instigated, supplied or inspired parts and ideas.
Here are the progress pictures I took - sorry they aren't in logical order:
