What you use for output? MKT+1R or Muse + jumper in place of 1R? I see both.

What is that 100R in series with an output node?

Output = MKT (wima 3.3uf) + 1R
BIB C101 = Muse 220uF

So the upper Muse on your board the one near the MKT is a missing option in the actual build? Then it would be OK.

yes that's correct (for a tda1541a)

And, if you don't mind, I will sit in a corner being ashamed of myself now for a bit....

The 100R was a remnant from an earlier regulator I replaced with the your reg... without it, everything seems a-ok...

By the way, what is the impact of using a higher base/gate stopper on a BJT (270R) ?
