Thanks Dennis,
I will change my setup and remove the 7815 so it get ?> 16V unregulated. I will use a 1000 uF buffer. That should keep the lowest voltage in the ripple above 16V, but that is easy to test on a mini-dynamic ( 0-1.5A 100Hz to 50 kHz pulsed with adjustable 0-1.5A bias) load I made for testing small ( < 3A ) PSUs that can be easy set at f.i. excact 40 mA and then pulse 20 mA extra?
Very handy for these sort of things

I just received a type 134 current probe amplifier with a newer power supply
I hadn't seen before. (see attached picture)
Instead of the classic power supply, Tek used a power cube (model 3310) that
came from Engineering Design and Sales.
Tek had their logo and part number (015-0058-02) engraved on the front.
Tek completely changed the power connector to the 134. They are now using a
2 prong power connector like you would find in automobiles.
It is a very big ugly thing. The power cube is 3 ?" x 2 ?" x 2".
Here is the important part:
Input: 120V, 50 to 400Hz, 10Watts
Output 26.5VDC @ 200mA
This is clearly way over rated for what the 134 requires (>16V @ 40ma) so
that tells me that just about any power cube that outputs >16V will work.
