For all interested in buying PCB`s of the PLL, I recommend you wander over to the other forum, Schumann PLL thread, and look at UKToecutter`s signature. There`s a link there for pre-ordering PCB`s. Get your name and quantity on the list, before it`s too late. Pics of the PCB`s are in the thread as well. Nice clean work.

Cheers,
D.

My buildup is now ready and works perfect with 9V (without inverter/doubler) :D

Some samples follow shortly :wink:

With all this talk of voltage doubling, why has nobody suggested a 1054 +ve/-ve doubler with an LM317/337 regulator for each rail? 1044s are terrible, IMO. Had so many burn out with just slight over voltage.

Wow, that sounds incredible!

The PCB run on these is sold out at the other site unfortunately, so it
looks like I am going to have to make the vero version.

Hey Sir

Can you post up how you wired it to just run off 9v DC please?
When the PCBs come in Id like to make mine as simple as possible and AC isnt really my bag...

cheers!

Care to share your layout/schematic/BOM?

That sounds freakin' awesome! Great job! :applause:

Just realised that isnt the same PCB layout, my bad.
still be interesting if you can share your own PCB layout / schem and inform how you run 9vDC please

thanks a lot ampbastler, :applause:

are the partvalues almost the same as in digits schem? there are only 5 ic's, did you use only the tl074 as amp and the cd4016 instead of the 74hc14?
can also post the bom for the schem, because of your fuzz & oscillator update :scratch: , that will be very helpfull! :mrgreen:

no!

Have to find out yourself :wink: the wiring diagram should already be a great help....

that's too bad, especially if you have benefited from others at fsb before.
but everyone must decide for themselves.
anyway thanks for the schematic

Dude.. Why did you remove my name and add your own? Draw your own schematic.
Super weak.
If your gonna use my drawing without giving any kind of credit at least SHARE your findings. Contribute!

Indeed Jonas, you and digit are the real heroes here...
It's only worth cloning for sale if the whole world doesn't have access to the schematic
