That's actually not my amplifier, I just used the picture to show what I was talking about regarding mounting the capacitors on the opposite side of the board from the tubes.

Usually if using DC heaters, I'll run the lines on be board, because the rectifiers, filter cap and regulator (if using one) is mounted on the board. Even though it's DC, it's best to avoid running the lines too close while parallel to signal lines. And also, if it's a double sided board run the heater V+ and it's ground return overlapped on opposite sides of the board.

If using AC heaters, I twist the transformer heater wires and solder them strait to the socket pins.
