VRDN: bipolar regulator PCB for line level ckts: ±11V to ±20V @ 1.5A with "De-Noiser" - Page 3

DontHertzMe · 6th July 2020, 06:49 PM

Boards for my layout are currently in production at JLCPCB. Once they're in hand I'll test them for stability etc. If all is well I'd be happy to post the gerbers here (with Mark's permission).

Mine are 2 layer instead of 4 layer (for cost reasons), size a bit bigger than Mark's at 10 x 13cm, and 2 fewer capacitors

Hi, I prefer that you open a new thread with an informative title perhaps such as "VRDN Clone on 2 Layer PCB" or something like that, so members will know instantly that it's just a little different. By all means please post the Gerbers and I'm happy they will be freely available. Just not in this thread, lest confusion arise.

Thank you and congratulations!
Mark

Would a 100VA 18V Antek work well with this board?

6L6 · 9th July 2020, 09:33 PM

Yes.

It would be total overkill, but it would work nicely.

RickRay · 9th July 2020, 09:40 PM

I figured, I have one on hand and antek is out of stock on the 50VA. It will fit, i guess I'll use it, LOL.

6L6 · 9th July 2020, 09:41 PM

Absolutely. It will be under low load and will likely run hum-free and happily cool.

Hi Mark
hi everybody

Mark, thank you a lot for all those contributions you provide.
My line stage-kit will be arriving soon, so I'm getting nervous about the VRDN which I intend to use for it.

Since it got a bit quiet here, I couldn't resist and got myself a peek into the Gerber-files. Being on a mac, I had to find the appropriate tool for it and settled on "Cuprum", which opened / imported the zip-file without complaints. It looks cool and I don't know what to look at. So if I'd give it a shot, it would be with blind faith!

I don't yet know if all I'd had to do was send this to some PCB-maker...
I just tried it with the first I found: Eurocircuits, and they want some € 88.- /piece so that's a no-go.

Would somebody assist me, or has anyone some PCBs in the pipeline already?

thank you
david

I got 10 made at jlcpcb.com for 30.4 EUR. They accept the zipfile provided by Mark Johnson directly.

I have attached an example of specs for ordering.

+1 on JLCPCB. They're solid quality for little money. PCBWay is also a good choice.
