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.
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
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.
