LDO Regulated PSU for Preamps

I am wondering if wouldn't be better/easier linear stabilisers L7915 and L7815. Why this is better?

PS: I have no understanding to that circuit, this is why I ask

Maximum current is 10A, you can use it for AX14 stereo

10A out of a BD139,140?

never, but you can get it out of the MJ15004 and the MJ15003, BD139/BD140 was the biasing transistor replacement.

I believe you are confusing the PSU10R with the LDO. PSU10R is the one that is 10A.

Aaah, yes it seems I am confusing it with the LDO. My apologies

Nice PCB.

PSU10R

I believe the the outputs are reversed.

Bridge and caps polarity are reverted on PCB.

Wow I see now. How's this?

your DC voltage marking are swapped - need to change sides. nice job.

Good eyes!

I would love to see a built PSU10R, especially what gets done with the MJ15003 and MJ15004. How the heatsinks are mounted

 

[bullittstang]

Good looking PCB. Do you use Sprint to make/edit pcbs? I just bought the program and started toying with it and after a week, I’m still terrible but starting to get the hang of it.

Good eyes!

MJ15003 E and C are reverted...

 

[still4given]

MJ15003 E and C are reverted...

Thanks Mile

 

[ballisticz4]

Still4given, you threw that one in to confuse us, right


These have to go on heatsinks, seeing that it can supply upto 10a. Was just wondering how you guys did your build with this PSU10R

Postovani,
da li imate visak 2 PCB. Kupio bih ih.

Pozdrav Misa

 

[apexaudio]

Thanks Mile

Nice work, but go to PSU15 with mosfet outputs.

Dear all,
do you have a surplus of 2 PCBs. I would buy them.
