Hi, I'm looking for information about Marmac amps, built in Sligo during the seventies.  I've seen several Binson amps that appear to be Marmac amps with Binson badges.  What's the Marmac/Binson connection?  Also I noticed that Marmac amp head cabinets seem to be nearly identical to Matamp cabinetry.  Was Marmac connected with Matamp?  Finally, I noticed someone is selling a new knockoff of a tweed era Princeton amp on fleaBay that has a Marmac badge.  Does anyone know about this "new" Marmac venture?  Cheers!
