Densen B-150 schematic needed

Output DC offset by another issue? Did you try to measure before the relay with a scope? Anyway, greetings to Denmark!! 🙂
Pavel my lost friend 🙂 Thanks for responding. Didn't come to dismantle the unit yet, but have now did a further test.
Not very much familiar with Densen products, but can see in display and by hearing the clics that's the volume clicking that up from 0 to 100 (can step up to 200) at power on. The owner claims that's a new issue..... Maybe I need to look for the owners manual 😉
Thanks for the greetings. All well here! And the best greetings back to the lovely Czech Republic.. Hope you're not to much affected by Puhshits war??
