This should be the place to post this. Basically I was starting to clean up my Heathkit AA-151 tube amp and what do you know... no headphone out jack anywhere to be found.
How do I go about grafting in a 1/4" headphone out jack on this beast?
My headphones are all higher ohm ( 600 and 400 )
I noticed the speaker connections go from 4 - 16 ohm and was thinking I could somehow attach to these using some sort of cable I could make up while speakers were on at the same time, maybe a switch thing. Anyhow all I am concerned about for the moment is can it be done ( reasonably ) and if so what are the options for doing so.
This is the clearest picture of all the connections on these things. My camera is not as good so this obviously is someone else's. I had a schematic lying around somewhere. If I find it I will post.
I had hoped by chance that the matching tuner would have had a jack but nothing there either. It would have given me an excuse to buy one
SCHEMATICS I am useless at this but it may provide some answer to the electro-geniuses in here

hopefully they can be expanded when saved.
Thanks for any insight.
