GB for Salas Folded Simplistic Phono PCB
I am proud to offer the Salas Folded Simplistic Phono Preamp PCB.
In Salas words :
"It uses a folded cascode input stage, passive RIAA filter, common source second stage, a source follower buffer with constant current bias. No form of feedback between stages is employed.
It can be made for different voltage gain. Input load is switchable. Suitable for LMC-MC-HMC-MM. (see build guide)
There is an official double layer PCB available for it that carries two channels and two MOSFET
It comes in one piece and it is pre-grooved to be breakable into separate channels."
The PCB is available for $52USD (~39 Euro).
The shipping costs is 8.00 USD (~6 Euro).
Accepting USD PayPal only.
This project took significant development costs and a long time cycle. It will probably be a limited edition for one or two runs depending on demand. Good components and nice boxes for it will be money well spent judging from my prototype's sonic results.
Minikits will be made available as well and will contain limited parts - resistors and transistors for the Shunt supply portion and the RIAA caps VISHAY MKP 1837.
Please subscribe to this thread as well as check out the sign up spread sheet for "Salas Board" in my signature.
The GB will close on September 22nd.
Payment is via invoice only. Please send me a private message with PayPal email and I will forward you an invoice based on spreadsheet's data.
Here is the minikit details.
It is designed to allow for a bulk packaging of parts to get transistors and resistors for the power supply, and some small parts for the phono section.
Price is $48.00
