no pix needed. Manuals fine Thats quite a nice oscillator. 20 watts ac and 8 watts DC. That makes a nice reference indeed. Easy to run on battery. The 20 W on ac is because of the transformer and regulator inefficiencies. I just changed a xformer out to a switched lo noise supply. Went from 16 VA to 3 VA no load. Nice power savings for a 7X24 thing. Regards Paul WB8TSL
