GB for Salas Folded Simplistic Phono PCB

[RCruz]

I am in for two boards

 

[Joshua_G]

I would be in for a board and a kit of parts, more parts in the kit would be preferable.

My preference is the same: as many parts in the kit. Of course, matched pair of 2SK369BL for 63 dB gain is a must.

Welcome Ricardo🙂

 

[nezbleu]

I'm in for one boards, probably a mini-kit depending on price and contents.

 

[Marra]

63 dB gain is just right for me so looking for matched 2SK369BL as a must and the caps if I can have them all the rest if possible... I am shure is going to be a realy good one 😀

Likewise thanks

 

[Salas]

big roadblock is obtaining matched 2SK369BL's.

I have included a table for 10-15 mA 2% Idss tolerance 369 matches in the guide. That is I actually tested them on the breadboard with the source pin resistors mentioned.
So its a broad range that should make many samples usable. When they run at about 9mA bias after degeneration with proper Rs they present the same transconductance.
So if you got 13mA samples you know what resistors. 12mA, again you know, etc.
Use the next nearer mentioned resistor for midway Idss. I.e. you got say 12.6mA match use the next higher mentioned Rs. I.e. the one for 13mA. If you got 11.4mA use the resistors of 11mA etc.

P.S. It will even work with same IDSS & Rs table K170s at input but in less gain and bit more noise. A compromise.

Took the liberty to add it up. If everyone could please check.

Big thanks to Salas and Tea-bag

Is everybody updating the spreadsheet?

Yes, please use the spreadsheet.

I don't know if its the plan to update here. I have updated the "excel"

[evanc]

I added my name to the spreadsheet for 2sets of boards, and 2 parts kits. I am looking to build a balanced preamp.

[tiept]

I just added more kits to my other GB orders. 1x board 1x minikit. I prefer to have as much parts, including the matched 2SK369BL, as possible.

Thank you Salas and Tea-Bag.

 

[PUCHG]

3 boards and 2 minikits for me please.

 

[Tea-Bag]

I have added a column for 2SK369BL in either pair or quad. (pair for less gain)

If you choose to buy them from me, this will help indicate demand. I currently have 10 sets of quads.

 

[evanc]

I put myself down for 2quads of the 369bl. These don't seem available through normal channels.

 

[Salas]

We will much likely not be able to enjoy a max gm least noise Toshiba JFET sound again in the near future. The semis industry moves otherwise. BJTs can technically stand but sound different. This one will become a rarity phono example soon. Build it well.

 

[skunark]

I'm also in for 2 boards, 2 minikits and 2 sets of quads. (added myself to spreadsheet)

Thanks

 

[quan]

Add my self to list with one set of quads please.

[skouliki]

Added one set of quads for me
