the regulator board purpose for general use.it can be used in all standard LM3875/3886 IGC or NIGC designs.Even a solid state power amp,such as JLH.

hrer is 3886igc and regulator PCB boards group order page:3886inv gainclone PCB,group buy
I will accept order from today till October 10.

Digi,

Have you tried your circuit? How does it sound? Please let me know what the advantages are when using your regulator. I'm probably interested in a set of these.

The LM338 regulator can be used in non-class-A JLH designs, but I am not so sure on class-A power amps. How much are the demands in current for JLH class-A amps?

The regulator PCB is based on LM338,it is capable of supplying in excess of 5A over a 1.2V to 32V output range.
A 10 Watt class A JLH,the Iq usually set at 1.2A, 27V.it can work fine.
JLH 10 Watt class A amplifier

You can find more detail about LM338 psu and JLH amp at here:

hook method,

There are two assemble methods,wish it can be helpful.

Thanks Digi i got mine a few days ago from Dave... I got 8 boards. Just got to order some parts now. : O ) They look GREAT!!...


Do you know about any other deviced being able to drop in and get a higer voltage ?

Jason..

JasonL,Thank your appreciating
LM338 can be suitable now,it's input voltage is 32V(max =40v).LT1083 is all right,but expensive.If the amp need high current and high voltage,It is more worthwhile that I think is unregulaotr method.
the board be able to drop in LM317 chip for peramp or headphone amp using.

btw,attach the board via pad assign.it can be hook wires for unregulaotr & regulaotr using.

IIRC the LM338 32V limitation is how much it can *drop* (difference between input voltage and output voltage).

So, it is suitable for high(er) voltage just fine. I think. I never really paid attention to whether it has a maximum since I have no projects that would need anything particularly high at the moment.

so to make sure i understand you. You can make it a regulated PSU or unregulated, as you show in the pic?
