I was dropping off some items at the thrift store the other day and noticed a pair of AR-5s sitting on the tarmac so I went back the next day to see what they looked like and ended up buying them for a song, literally. I bought a pair when I was in Germany back in the mid-70s which had oiled-walnut cabinets and dark grill cloths. The thrift shop pair have Formica laminate finish and light colored grill cloth. I wasn't aware that AR used Formica. Anyway, these speakers sound great to my aging ear
Oh yeah...nice catch, Roger...and the yellow wires should be connected to "T". Carl's going to have to issue a recall on this one. Since then we've also learned that the resistor is supposed to be 1.5 ohms not 1.35 ohms, and earlier AR-5's will have #6 and #8 coils instead of #10 and #11 coils. Attached is an "official" AR-5 schematic. Not as pretty, but more accurate. Roy AR-5 schematic (from AR).pdf
