Thanks!
Also, here’s a little more info on the A-1 which can be hard to find, especially the TR137,138,139,140 arrangement and listing in earlier SM’s.

I have no direct equivalent for those there, we will have to do cross-checking on the net.
!!!pay attention to the different pinout !!!
2SA914 ⇒ BF416 BF470 BF472

These have also been recommended.

Can you explain to me how you do to select image windows in a pdf document?
I can't do it and when I find myself with a diagram of this size (that of the yam in the service manual) that I therefore cannot visualize in full, I would like to be able to select pieces of the diagram and extract them from the pdf document
