Kennedy 9800 near L.A. - Shipping help?

Hi friends, Would anyone near Santa Clarita, CA be able to assist in packaging a Kennedy 9800 tape drive for shipment to NYC? The auction ends tomorrow but I'm reaching out to the seller to see what his/her flexibility is on the collection date. Looks like the unit is 50lbs. -- Anders Nelson +1

Strange grounding problem

Hi folks, This is another Grundy Newbrain problem on a different machine that is probably easily explained by someone who understands current flow. This machine has two startup circuits that are simply a resistor and 10uF capacitor each, both feeding a Hex Schmitt Trigger (CD401068CM). When
