F5 Turbo Circuit Boards

[pcb121055]

Hi Audiosan/Variac, outstanding news that the boards live on. Shame about UK although he did appear to put in a lot of work on the project. Seemed to be really patient. Moving on... is the plan still to market these boards thru the DIY store?

[AudioSan]

hello pcb yes. they will be sold at the store

Will you also finish the PS Boards?
I realized that there is no big PS Board available. So that would be also good for other huge amp projects and therefore a nice product for the store.

[AudioSan]

no. there will not be a PSU board. the ones that are in the shop no can be used for V2. one board pr ch.
for V3 its better to use cans.

TeaBag is working on a large format PSU board. Contact him if interested.

Variac (and Audiosan and Teabag):

UKToecutter is gone? That is not good news. Please tell us that diyaudio will make a power supply board available that is suitable for 16 of those gorgeous Nichicon KG (35mm dia) caps that I just bought through Buzzforb's F5T group buy.

Please, please, please!

Regards,
Scott

Guys,
The current plan (for board Buzz mentions) is to use a 4x each rail 35mm diameter caps for a board that is built to be compact as possible, but still use Panasonics 4pin 35mm 22,000 50v caps, or larger ones with less voltage. It is meant to be a generic dual rail power supply, but carry enough capacitance to work with F5T. At the time of development, all of the F5T stuff CRT and myself have been designing was meant to be an alternative to ToeCutters work, for different purposes. Buzz's group buy was to cater to that.
If anyone has a functioning board and the Gerber file for the Toecutter Power supply, I don't mind getting a limited amount of them printed up. But as I understood it ages ago - there were some layout issues with it.

If you want to build a real powerful amp you need 63V caps. The 4pin 22.000uF Panasonics with 63V are 40mm. 4x40mm cap per rail plus space for MUR3060 diodes on heatsinks would be my wish. Maybe solder lugs to connect a off board power resistor for CRC use.

I think Toecutter had worked out the few issues I pointed out. Can you make a gerber out of a pdf?
So he is not part of DIYAUDIO community anymore?

Not that I am an important member/contributor, I have thought about if I die or suddenly become unable to be a part of this community, no one that personally knows me would ever think to let the community know.
I certainly do miss Toecutter and would miss many contributing members if they suddenly stopped posting. I should tell my wife to post a message somewhere if that happened. Wonder where it could be posted?

Rush, your getting too deep. That said I think we've lost 3 people for sure in my time here.

I have never heard of scanning a PDF to gerber, especially if it's dual sided.
