I cant seem to find the best way to hookup head phones to a pas 3x , st 70 setup? Has anyone been down this road before?
Head phone on Dynaco?

You may want to try a set of e'stats that use the amp output. Tube units for the most part did not have headphones. Another way would be to build a box that has the headphone jack using something like 500 ohm resistors going to one side of a switch and the speakers to the other side so you could switch between them. Lastly, of course would be to get a separate headphone amp and use the ST70 for speakers and the other for headphones.

i solved the problem by getting a set of koss esp6 'phones that hook up to the st70 outputs. good deal for 5 bux!
Try looking at some of the original manuals here

The manual for my SCA-35 had a section on adding a headphone jack.

The SCA 35 addition is simial to the 2nd idea I presented. He went with the first. The difficulty with the PAS/ST70 as the amp does not feed back into the preamp and hence have to figure out how to do it in a manner that will allow for switching and access. I have a SCA35 and if I were to add phones, I'd not put the jack on the back as suggested in the manual. Too difficult to connect and disconnect and as the amp gets so hot, I can see burnt flesh from time to time.
