I can not remember except to say - The Internet. Now that you mention it I will go look for mine and be sure I can find it. I replaced the batteries in it recently. You have to use a 12 v and a 3 volt battery at one place. The 3 volt button battery does not last very long. I have also just acquired a Heathkit MM-1. Best to you.
Found the manuals and built the battery pack, 15 VDC, but the meter reads low on all the voltages by 16 - 23 %. The ohms scales aren't responding either, looks like I got my work cut out for me. Maybe a winter project. Thanks for your response... an MM-1, hmmm, maybe I'll get one of those also. Take care.
Where did you acquire the manuals. I just love the oldie but goodies. Nice video. Thnx
