Steve Wedge, W1ES/4 All Messages By This Member #83906 The K4OAH service manual has a photo of the component side of this board (Board 5) but no etch layout. Q5 is right on top of the harness.? Keep in mind that these older transistors' layout is different.? When facing the front of the transistor body (the flat side) the lege are, L - R, C-B-E. Steve Wedge, W1ES Time flies like an arrow.?
