Perfect Parts Kit!

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!

F5 kit and PCBs

As expected, first rate in every way. Where else could you expect to get this standard of parts already selected and graded.

F5 parts Kit

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 !
