Hello all.
My dad is what I'd call an accomplished amateur and is forever hunting for old circuit diagrams online. I appreciate you often have to pay for these and I was hoping to buy him a subscription to a site where he could do this.
I know NOTHING about the subject so would be very grateful if somebody could point me in the right direction or give general advice.
Thank you all
Pete

 

Hello,

What kind of circuits is he looking for ?
There are some sites specialized in old books and magazines:

The internet archive has also a lot of information and books for electronics:

In what field of electronics? there is too many to count.
Or does he collect anything?
Does he have an object in mind for the collection?

Maybe another new member will show up with a recommendation.

 

Thank you. Dad likes repairing complicated electronics such as oscilloscope /transceivers/TV. The one we were looking for today was a circuit diagram for a digital counter board. He worked on all sorts. Pdf workshop schematics. All that sort of thing. Sorry but I don't really know what I'm talking about.

Sorry. I don't understand your reply???
