Possibly a grounding or wire dress issue or RF pickup. With no input hooked up, it is hard to say from a distance. The circuit, as designed, has regulated supplies (capacitance multiplier) for the entire amp, except for the drivers and outputs.
Hi Igreen
Your description of this amplifier’s sound is very accurate. I,m using my Krill (100W version) on a daily basis since almost an year now. It is a very reliable (love the bass) piece of diyaudio (thanks Steve)
Good work!

I am really pleased that you like it. Would some of you tell us what speakers you use? Others here might be better able to get a feel for how it would sound in their systems.
Hi Steve
Good to read you!
I’m using Heybrook speakers (British made) around early eighties – 3 way closed box, “Seas” drivers; 10 inch woofers. They are not modern, but drivers are new – (I rebuilt them a couple of years ago) – very good sound. A good match, in my opinion.

That's good. I want to find out what different types of speakers work well with my amps. I know they have been used with electrostats , planer, ribbons and assorted box speakers. So far, they have worked well with everything, but there could still be something out there that gives them problems, although I doubt it.😀
Speakers
I've used it with-
- Infinity Kappa 7
- Von Schweikert VR 4-Jr
- Snell Type E II
But I did not really crank it with the Kappas, played it loud but not full out like I did with the others. I may do so later, but having worked on this for many months I don't want to blow it up quite yet.
I was thinking (and I put this on the web page) that this amp would be good for people who think digitial (or their present system) is harsh and bright. It really smoothes and relaxes the sound. Just my 2 cents.

My Krill powers (depending on the mood) a Pair of Leak Sandwich speakers from the mid 1960's or a set of Gallo Spheres and a sub.
Have to prefer the Leak's (16ohm) but they are disaproved of due to size so the Gallo's rule 🙁
works well with both
