Correct VAC Output for HP-97 AC Adapter?



#2

I have an HP-97 but no AC Adapter/Charger. So I'll probably make one. I am not sure of the correct output voltage. The HP Museum says 8 VAC, but the Service Manual says it is 12.8 VAC (Section 2-42 pg 2-5).

Can someone with an adapter perhaps measure it for me and tell me what it really is?

Thanks

I don't have a voltmeter, but I have three 82059 adapters.

The all have engraved on them 8VAC 3W MAX.

Does this help?

#4

I have the same adapter as Les. Printed is 8 VAC. However I measured the output as 12.7 VAC. Hope this helps.

Egan: Your 12vdc would be the unloaded value. In series with a battery it would probably be more like the nominal 8vdc.

Dan: Making that plug is going to be a drag. I have a spare. Do you live near me?

I live in Phoenix AZ. A bit of a drive. Would you be willing to sell one?
