Not necessarily for test.
I use these routinely for building.
This way it's easier to repair, if something dies, it's most probably a semiconductor, so in this way no need to disassemble or solder.
But if I want to experiment with the components, that's easy too.
As I see attached photo, there is a mistake.
On right panel R32 is other way around.

Really?
Yours is some of the nicest, most consistent soldering I have seen posted here. Cleanest too !
Good news (I think)
Previous measurements:18.6 at the positive, and 12.8 at the negative, both boards.
New measurements after fixing the mix-up between the 7815 and 7195: Left board: + 8.35, - 8.57; Right board +8.31, - 8.57.
R27 is now 2.41 on left, and 2.72 on right.

Between one of the legs of R19 (the one goes to the collector of Q8) and gnd you should get 15 volts.
Could you make a measurement?

Yeahh...... but obviously at the wrong places/measuring points.
Try to measure between pin 2 and pin 3 on the 7815, and between pin 1 and pin 3 on the 7915.
Waiting for the results 😉
Sorry...i was following NP's instructions for values, i think...though i must have misunderstood. Will give this another go tonight. As always, thanks for the support and the patience!
"... I just thought it would be safer not to perform the measurement on two pins that are only 2.5 mm or less apart...better not to risk a short circuit..."
Particularly since i can't even see 2.5 mm. What an S-show life is when vision fades. Still looking for the upside. Maybe it's that i have an excuse for poor spelling.
