Selling as a lot only. Will not separate. My dads old testing equipment. All worked when he passed away. All stored in the house.1) 1960's-70's Heath Co. vacuum tube tester model I M-10. 2) 1960's-70's Heath Kit RF signal generator.Model RF-1. 3) 1962 or older Hewlett Packard Vacuum tube voltmeter model 400D he put a new cord on it. 4) 1060's ? Allied Radio Corp "Knight Multimeter" made by Simpson I know nothing about this unit. Cosmetically not nice like the others, it's a little crusty. Due to their age I have to sell them as-is. No returns. I did research on all in non- tested condition, this is a fair price. Cash only, price is firm.
