diyAudio F5 Build Guide
Well... I am working on the new guide.

Here's an "in-progress" sneak peak. Might help you out.

Amplifier schematic. Print out and have in front of you at all times.

Right - PCB bag. Left - Kit of F5 parts.

The current F5 PCB from the diyAudio store. It has the inclusion of potentiometer P3, and is the third revision of this board, hence "F5v3"

The parts kit includes everting for the PCB except the input Jfets and the LED

One channel's parts

The Dale resistors have thier value printed on the side, the code is 3-digit + multiplier at values greater than 100ohm, and below 100ohm the "R" is the decimal.

So, from top to bottom you see
10K (100+2 zeros, 10000ohm)
1K (100+1 zero, 1000ohm)
100 ohm (100+0 zeros, 100ohm)
10.0 ohm (10R0, 10.0 ohm)

Click the image to open in full size.
Lead spacing for all small resistors is .5inch (12.7mm)

Measure all resistors before inserting into the board!

Right side

Big resistors installed. Blue are 0.47ohm 3W, Orange are 100ohm 3W. Values printed clearly on the side of each resistor.

Click the image to open in full size.

Note that the parts kit does not include the LED or it's resistor, this is so you can choose that you prefer.

Click the image to open in full size.

I used blue and a 15K resistor



Click the image to open in full size.

Install the 5K pot and the ZTX450 on this side (Q6). Note the orientation of the transistor. The potentiometer value is almost the same code as the resistors - 502 is 50+2 zeros , 5000 ohms


Click the image to open in full size.

Q5 is the ZTX550, note orientation, and use another 5K pot here.

Click the image to open in full size.

The 200ohm pot mounts in the center, and the Jfets install as shown. The K170 is the N-channel, the J74 is the P-channel.

Click the image to open in full size.
Mount the thermistors as shown and don't bend then yet.

Thank for your clear and well illustrated build guide. I just finished building the amp boards, I used a build guide from 2012. In this build I noticed that the pots were mounted the other way around as well as the jFets. Am I missing something? If so I will have to desolder every thing. Thank for your reply.

The attached photo has this blue what looks like a thermistor. The BOM and the schematic only lists the CL60 but this one appears to be different. Can you tell me what this is so I can order one?

That should be a x-rated suppression capacitor. Perhaps one of these:

Mrshazbot - Dennis is correct, that's a 3300pF line-rated capacitor.

His link to the part is a perfect choice.

Interesting, why is class A not good to start?
I've built a chip amp and a tripath, but those were on guides where I had a diagram of where everything went, rather than a schematic.
Thanks
