MOJO is selling the so-called "mustard" coupling caps. They call them "Dijon" caps. These caps are branded TAD in Europe. You can see them here (scroll down page): http://www.mojomusicalsupply.com/cgi-bin/mojotone/scan/co=yes/fi=products/rf=sku/sf=prod_group/se=Electronics/op=eq/sf=category/se=Capacitors/tf=brand Germino is now using these. They are replicas of the caps Marshall used in the 60's. MOJO has the common values. There are a few more values available in the TAD line. The prices are reasonable, even at retail. Time to heat up that soldering iron?
