will someone please tell me the ohm output on a 60,s blackface concert head and the best 10 inch speakers to buy for it.thanks pit

Fender 60's Concert HEAD? No such model unless someone pulled the amp and had it recabbed.

If it is original head unit it woudl be an early 80's Concert head. They were the last of the Point to Point wired amps tube before CBS pulled the plug.

These were great amps with channel switching, and a cascading preamp on the lead channel with a pull boost on the mid knob...if it has eleven knobs it is the early 80's model. They came in a couple different configurations...head, a 1x12, a 2x10, and a 4x10 speaker cabs. These are great amps, and are 8Ohm amps...I have the 2x10 model and it is dead mint, I bought it new in 84. Here is a pic...it is the one in the middle.

What time is it? It's Fender Time.

The AA763 Concert Amp chassis is configured for a 2Ω impedance load. The original speaker array consisted of 4 x 10" Oxford 10K6's or Jensen C10R's of 8Ω each, wired in parallel.

Were this my amp, I'd run a quartet of CTS alnico tens. YMMV
