F5 parts Kit
This is a stuffing kit for the F5 V3 PCBs.
It does not include the JFETs for Q1 and Q2 or the F5 PCB.
See the PCB page for more information including the F5v3 Build Guide.
Good for 2 channels.

|Part||Value||Qty.||In this kit?||Notes|
|R5, 6, 21, 22||2.21k||8||Yes||A few extra 2.21K resistors are included for the R5 R6 positions in case extra series resistance in needed to get the bias up to proper levels. Most builders will not need them, but they are nice to have on hand.|
|R7, R8||.47R 3W||4||Yes|
|R9, 10, 11,12||100R 3W||8||Yes|
|R13, 14, 17, 18||100R||8||Yes|
|Q1||2SK170||2||No||Source Q1 and Q2 Separately as 2 matched NP pairs*|
|Q2||2SJ74||2||No||Source Q1 and Q2 Separately as 2 matched NP pairs*|
Used the parts kit and PCB only.
My PSU is based on two Meanwell PSUs, one for each rail, 24 V and each rated 200 Watts. This gives me -24 V, 0 V and +24 V.
My case is a Streacom DB4 PC case. It appears to be sufficient for the cooling. The outside temperature on the 4 sides is 56,7C, 39C, 54,9C, and 39,7C.
The F5 sounds great! I can highly recommend this amp!
As expected, first rate in every way. Where else could you expect to get this standard of parts already selected and graded.
quality parts kit that made things easier .No sourcing from different suppliers, which more often than not costs more due to shipping alone .my f5 is playing beautiful music .Now i will be using diy audio store for all my first watt builds and other builds as well .thank you guys for this i highly recommend diyaudio to my friends and anyone else building these amps or kits. Wonderful store and exceptional service .
Beautiful PCBs, all received as mentioned, an excellent kit, but it always the case with the DIY store.
I wish the LED and its resistor were include but no big deal.
For the Jfet , it seems more complicated as they must be paired.
But "in fine", the kit is a big time saver and well done !
Thanks for being there for us you guys! I sure appreciate how carefully packed, well curated, and the attention to detail that is found in the offerings here. It keeps this hobby fun and takes all the work out of it! :) Cheers.
First class kit, build the F5 and the sound is verry, verry good. Thanks folks for top sound for little money.
Thank you very much for the great service and delivery.The products are of excellent quality and I will surely be returning to your store for future needs
