Gentlemen; Another SB-1000 question.. Among other parts I lost when the 7.5 V Zener went out, was the 0.6 ohm, 3 W resistor on the meter circuit board. I've e-mailed Ameritron with no reply, and searched Oceans Electronic, Mouser, Digikey and Jameco with no luck . Does anyone have a source for this part. Thanks in advance. Charlie, K0GPF
