Thanks stajo 1 KHz.

It would be intresting to see a sweep, for ex 20, 100, 1000, 10k, 20k, 50k. Only if you like ofc.

 

[merlin el mago]

20Hz

 

[merlin el mago]

100Hz

 

[stajo]

20Hz

Fairly expected

 

[merlin el mago]

1000Hz

 

[merlin el mago]

10K

 

[merlin el mago]

20KHz

 

[stajo]

10K

Wiggletime

 

[merlin el mago]

And 50KHz

1660 was gaped for 10 and you run 26 at 5,5? You loaded outputs?

 

[merlin el mago]

No

 

[stajo]

Put some 100k over and measure again

 

[merlin el mago]

10KHz no load

Also, make a frequency sine sweep with the generator - from 1K to 100K Hz - and look for variations in the level of the output. Usually there is a resonance around 50KHz.

How many W?

OK I will do George.

 

[stajo]

Any

 

[merlin el mago]

10KHz loaded with 10k

10 k is to heavy load
