For 30V you will have to adjust R4/R104 to somewhere between 12.75K to 13K. The proto's have 12.76K on the positive side and 13K on the negative side. So prepare for a little tweaking if you want excact values on the rails. Trimpots were used to arrive at those values. The boards has provision for 2 pcs // R4's and r104's to make it easier to do odd values.

Guido and all,

The etch file for the Toole shuntreg is bigger than allowed to post on this forum so anyone interested on it please PM me and let me know if you need a cooper or component side view for your transfer process. The files are available in pdf; no gerber’s have been done.

This is what the boards look like
Apassgear did a tremendous job on those boards. The etch file is very DIY userfriendly!
The Toolereg doesnt run overly hot! It is pretty easy on the heatsinking! Ofcourse it depends on the settings made by the user, but if the general recommendations are followed, only small heatsinks are needed.

Default Etch file for the Toole Suntreg

To all who requested etch files for the Toole reg I have sent a layout file with both positive and negative components for you to follow through the construction, makes it easier.

The other file contains the artwork for transferring to your board, there is one seen from the component side and another from the copper side for you to select the appropriate one according to the system you will be using. Make sure that it prints to scale.

Please let us know thru the forum on your outcome and what you think about this project.

Steen,

Those PCB's really look great. The process your following has an excellent resolution I can even read the lettering thru the pic you posted.

I might even be doing a compact size artwork for the Toole reg for you to test, I remember those you did for the NS10 which had thinner traces and they came out fantastic too.

Thanks. It is the usual photoresist method. It is much better than tonertransfer and all that. Photoresist is far more consistent in giving good results.

Default Toole shuntreg

All etch files and layouts requests until yesterday have been sent.

Please remember that positive and negative reg polarities are built using the same PCB and that instructions for setting the regs are shown on the schematic file.

Please direct all questions you may have thru this thread so everyone is benefit with your experience.

Cheers
