I have changed address as I told you was happening, check your email for details please. I hope you did send it already to the old address. I only made certain this new address yesterday, I have set up mail to be redirected, but all the same it will take longer and I dont like putting faith in the post office.

if you have, I guess no problem and as I said in the email thankyou for your hard work regardless, i'm sure it will find me either way

Thanks...

They are properly terminated without load by the output cap's ESR. You can overheat them though if holding all CCS current in and having small sinks. Don't forget to make remote and force ends meet.

Salas! I am mounting some big sinks and will watch heat during testing.
One other question-is it still an advantage to use remote sensing if the distance to the load (wiring) is kept short: <7 cm?

Yes boards are turning up all over oz it seems, it was my last night sleeping at the old address last night and was downstairs packing this morning when a very characteristic padded envelope was left propping the letter box open. They look good, guess I better start scavenging some nice parts for them. I have all these nice film caps left over in pairs from when I used such things in single ended circuits, so I'm going to try out some 4.7uf mkp bypassed with Vcap cutf 😀 going to prove to myself once and for all if there is a subjective sq difference rolling caps in regulator. I'm scared

the B1 and the DCB1 can be assembled without a PCB.
They consist of very few components.

The Salas types regulator can be sourced separately.
Quanghao is selling PCBs with 4 versions of the Salas style regulator on the one PCB that can be split apart at the Vgrooves to make 4 separate regulators. Each has it's own rectifier and smoothing cap.

Don't bypass the electrolytic in the reg's output with a film cap. Its looking for oscillations. You can bypass the electrolytic cap across the trimmer only for subjective evaluations.

I'm confused, at what point were we talking about B1/DCB1 here?

Did you post in the wrong thread AndrewT 🙂

Anyway, Quanghao, if you've got any boards left from the GB, let me know.
