Thumbs up Tested my two regulators today

At last I have done the checking test on my two cards .

They was soldered and ready 10 month ago ., (almost finished at post #178).
But I havent really got the time and was also a bit afraid of what the stress and concentration this function test would do on me

I mentioned back at #178 I would try a National Semi LME49710 OP Amp. I did and it worked OK. Less then 2mV hash on scope.

I also did one card with an SMD OPA656. All DC levels measured the same and the regulator also worked OK i thought, until I measured and looked at the scope. I have a perfect 63MHz sinewave of 130mV ripple (RMS) So we are a few having radio transmitters instead of regulators, allthough mine has a weak oscillation.

I havent "listened" to any of them yet. I will try to get rid of the oscilation on the OPA656 one first. C13 maybe? I have not checked the T5 CCS. It should be more then 3mA. Could this have something to do with the small oscillation?

Anyway. More of you have to get your cards ready so that we can compare our results.

Is there an alternative Source for LND150?

Best regards

BSP135 can be used to replace LND150
But you have to solder wires to the legs feed wire to pcb

Best regards

BSS135 (T092) are no longer manufactured by Siemens, replaced by the SMD version BSP135 (SOT-223)

I'm reaching here, but I'm wondering if anyone who bought the HV shunt regulator boards has two that they no longer want. I screwed up royally with two of mine, and would like to start afresh with two new boards.

Any offers? You will be amply rewarded.

Hi I was wondering who have finished their HV Shunt Reg boards and have them working properly without Oscillation.
What op amp did you use? Anybody get this board to work properly (no oscillation) with the OPA656 op amp?
Thanks, Daniel
