My Pass F5 Build

[bibin3210]

Finally all the components for the F5 have arrived and I just started the build.

The F5 PCBs are from Jims Audio, components from Mouser/Digi-key and the Toroid from Torotrans.

I will try my best to capture each stages of the build and post it here.










I started with the rectifier and CRC power supply and completed populating the power supply section.

The rectifier used is STTA3006P and 22000 MFD 35v Caps. 14 AWG copper wire is used for P2P connection.

Price Breakup for the PSU:
1. 22000 MFD,35v Caps - 5.39 x 8 = 43.12$
2. 0.47 Ohms/3W Resistor - 0.53 x 8 = 4.24$
3. 2k2/3W Resistor - 0.59 x 2 = 1.18$
4. Shipping and Tax = 13.89$
Total = 62.43$ x 55 INR = 3433.65 INR
5. Vero Board - 50 x 3 = 150 INR
6. Rectifier STTA3006P - 80 x 8 = 640 INR
7. Heat Sink for Rectifier - 25 x 8 = 200 INR
8. Thermal Insulator kit - 15 x 8 = 120 INR
9. Screw Connectors - 6.50 x 20 = 130 INR
10. 14 AWG Copper Wire - 2 Meter = 60 INR
11. Solder - 1 Roll = 170 INR
12. Toroidal Transformer (18-0-18/12A) = 2400 INR
13. RFI/EMI Filter 15Amps = 250 INR
Grand Total = 4120 INR + 3433.65 INR = 7553.65 INR






















Thanks,
Bibin

Looks great Bibin. Could you explain why did you choose to use a bread board than making a PCB?

 

[Audiodoc]

One more query. The ei transformer that you are running is of higher output voltage thereby the dc outputs are 33 v on each rail very near the 35 v of the capacitors. Is you get a power surge from say 220 v to 250 v on the transformer primaries there is a risk of capacitor failure aka explosion. Better to test with the 18 v secondary toroid only.

Bibin, you never stop, do you? I really appreciate the step by step pics that you furnish alongwith the write up.

Thank you Captain. I prefer P2P with some high gauge single core wire for PSU and i am comfortable working with vero boards. Making the P2P connection in the vero board is really thrilling......I just love it.....

Thanks,

Thank you for the comment Audiodoc. It is an important matter you have pointed out here. It was just for few seconds i have connected it for testing. But before that i had measured the mains as well as the secondary volts. It was around 192 VAC on the mains other wise i would have used the other low volt tapping available on that transformer.

Thanks,
Bibin

Thank you Titus........how can i stop , DIY is just like making one after another and the journey continues.......:lol:

Another awesome build in progress :clapping: Kindly keep posting on the developments as you progress further along with info on all components/casing/heat sinks & their individual costings.

Thanks for being a guide for all of us Non-DIY'ers too!

Thanks for posting in detail,nice one.

Today completed a pair of XLR to RCA cable for the F5. All the components are from MX.






Price Breakup
1. MX 2 core + shield cable 2 meter = 160 INR
2. MX Gold Plated RCA PIN 2 Nos = 220 INR
3. MX XLR Female Pin 2 Nos = 160 INR

Total = 540 INR

Thanks,
Bibin

I love that artistic arrangement ! I had a chat with him over phone today, but didn't thought that he will complete this soon! LOL...

A pair of cables is as much DIY as I've ever done, and my soldering is a bit messy. It just amazes me that a person can make that pile of bits in your first pics into ...something that works ...and probably sounds great too.

+1 to that. Its been a while since I did anything on my own but I must say, like you, I too find it thrilling to use this approach. If one gets the soldering right, I think its better than using PCBs. Vero boards are cool.

Nice and clean soldering. Wish I had skill like yours. :thumbsup:

Curiosity from an electronics illiterate ...

What are the components on long, yellow-insulated wires, and what is the reason for them being mounted high off the board? Sticking my head out with a guess: anything to do with temperature sensing?
