''There are three different choices:
Paradise R32b PCB € 11,00 per piece (€ 22,00 for a stereo set)
Shuntreg only € 8,00 per piece
Calvin Buffer € 4,00 per piece (€ 8,00 for a stereo set)''
Ok here is how i understand it🙂
''Paradise R32b PCB € 11,00 per piece (€ 22,00 for a stereo set)''
Paradise phono pre boards with built in regulators. Two needed for stereo.
''Shuntreg only € 8,00 per piece''
Just the shunt reg from the Paradise phono pre which can be used to power other projects.
''Calvin Buffer € 4,00 per piece (€ 8,00 for a stereo set)''
Calvin’s lovely buffer.
Alfred’s add on buffer boards which can be used to replace the Paradise phono pre’s on board buffer or as a buffered line stage etc.
Hope that helps🙂

Thanks, that helps 🙂 Was too tired to read through all that pages but also found this information a few pages back.
Therefore I will be in for
- Paradise R3 Stereo Set (2 boards)
- 2 Calvin Buffer
Best regards,
Fabian
The Paradise has the shunts on each board🙂
If using the shunt pcb to power anything else I think it would be one board per channel.If I'm wrong I'm sure someone will correct me.

Alfred,
PM sent for pair of Calvin buffer PCB's. Can you or anyone suggest alternative to pn4391 to be used with input device 2SK170BL? PN4391 is difficult to get hold of.

I think the BOM is missing the 6 RIAA caps that total 33nf and the 2 that total 11 nf or did I misread it ??
Saludos,

Manolo: You are right - they are not included in the BOM - because people would probably like different values (look the build guide) or different brands.
Also opamp caps c91and c92 are missing, just going through all the parts to see whats missing and what I want to place if I want to change anything on the BOM.
By the way, has anyone tried a different RIAA setup ?? Such as the Cruz or Salas instead of the Gerhard Borresen one ?? Any comments on sound any comparisons ?? Any curves detailing the differences, or if someone could explain the differences, it would be greatly appreciated.

Questions
I have a couple more questions.
1.- As I commented before C91 and C92 are on the Amplifier Schematic but not on any BOM, why ?¿?
2.- C6, C7, C8, C9, C10, C11 on the PDF BOM are not on the Amplifier Schematic, ?¿?¿?
3.- C4a, C4b, C3a, C3b appear as SMD on PDF BOM, but as through hole on Mouser BOM, which is correct ?¿?
4.- C6a, C6b, C7a, C7b same thing.
5.- R104b, R204b are on the Regulator Schematic and show 1M Ohm, and on the PDF BOM no value, not on Mouser BOM.
6.- RIAA Caps not on Mouser BOM (Answered !!!!!)
7.- 470 pF Cap on Mouser BOM not on any Schematic.
8.- 2700 pF cap on Mouser BOM not on any Schematic.
9.- 1 Ohm resistor on Mouser BOM, not on any Schematic.
Not trying to be a pain here just questions regarding what parts should be bought or not.
Maybe there have been changes to the board that are not reflected in the schematics.
Anyway, thanks,
Manolo

Hi Folks, for all the people posting here that they want boards - please send me a PM, as stated in the original post. Sorry but I dont have the time to go through the thread and check all the messages, my inbox is the tool for organising the group buy....
thanks

Alfred,
I have sent PM for 2 boards of Calvin buffers but have not received any information regarding total cost including shipping. I want to check with you if this information has already been sent and if not, when we can expect to get the quote.
