Hi, Here are a couple tuning meters that you might need more than I. TS-80/U Navy unit, contract NXsa12591, think its for ARC-1 but don't hol= d me to that. 0-1 mA. Great condition. MT-31C Signal Corps unit by Bendix Aviation. 0-300mA. Glass loose, otherwise ok. Good condition. $10 each plus shipping. Rob Flory Hopewell, NJ
