For my part, sometime we can't find exactly the same component as the original pcb then i prefer doing my own pcb. In the same time for the cost i do several amps pcbs and power supply pcbs, for example the the F1J slot i have 7 other amp in a same panel...
I hope the build proceeds well.I watch with interest as i have all the parts to build a f1j including the case ffom the diysudio shop.I hope you will make these ums boards availble.
Hi Spades,
Making the F1 a more accessible project for other diyAudio members is one of my primary motivations in making these boards. I need to get the first build on them complete and verify that they work well, and then I will post the small number of extra boards in my order in the swap meet. I have started a list of people who are interested and you are at the top🙂. I will let you know before they go up on the swap meet.

This is a 140µ PCB thikness then no problem with the current...
Here are pcbs amps without power supply of F1J, Circltron, Aleph XMM and a main preamp board (with lcd pcb, ir etc) with little pcb which can give me the choice of any preamp.

jazzyj - looks like you are making good progress putting your projects together, thanks for posting the pictures!
I am making some progress too. The power supply PCB is together and all fit and went well, although at times I felt my 70W soldering iron was less powerful than desired when soldering to the large copper regions (even with thermal reliefs on both sides).

Hello yes i have several project in a same time, Hiraga 30w, hiraga le monstre, amps kaneda (50W,192HP) and a DAC preamp active filter.
As you see all my amp have approx the same structure for the cost.
For your circuit the clearance and the relief with is quite dificult to choose.
Next circuit you should reduce the relief width and keep with the same clearance it may be work better.

Just sharing some progress photos. The missing parts are either coming on a Mouser order next week, or if they are labeled with number that is over 100 they are optional parts not included in the original schematic of the amp. R1xx resistors are trim resistors that can be added to correct DC offset if needed (as mentioned in Papa's various write ups on the amp), and C101, C102 are for adding 10uF electrolytics for an F1J build.

Sorry for hijacking the hijacking the thread can anyone recommend a decent temperature controlled soldering iron.Mine have passed away after many year of service.I live in the uk also fantastic looking boards cannot wait for them to be available.
Just a couple progress photos for people patiently waiting for the boards. I am a bit slow, but I have not hit any snags yet. I am hoping for first power on the amp this coming weekend. Note: The leads from the transformer haven't been trimmed to length yet to allow favorable positioning of the transformer to reduce noise after power up.
