the 2200 uf caps should be I guess no more than 12.5mm and they should be audio caps?
thanks

Yes. And 6.3V rated. These caps at this voltage rating almost always have 10mm diameter and 5mm pin pitch.

Hi Shaan,I think that a picture of the new zobel configuration will be helpful

 

[shaan]

Hi Thimios.

The new zobel config is shown in the layout picture linked in post 1. C21,22 and R33,34.

Thanks Shaan.
Nice work!
I hope that I will have the oportunity to test this beast in the near future.
What is your sound card?

 

[shaan]

Sure no problemo!
It's on board Realtek "hd audio" chipset in a 2008 motherboard. Its output is horrible, but input is very good.

 

[JaredC79]

please add me for 4 of these.

Hi Shaan
Sory but I'll cancel my order, if there is no problem.
Thanks
Tome

 

[shaan]

Hi Tome.

There is absolutely no problem.

shaan,
Question on parts. What are you using for the 0.1R/5W resistor. I can only find Wire Wound resistors & the smallist one i could find, the body is 12.5mm long.
MFG P/N - RWHSE09TQ000R1FS

I was going to use these LVR05R1000FE12 Vishay / Dale | Mouser
but they are way to long, thanks for waking me up.

These will fit perfectly and are easy to get. Wirewound vertical mount resistors.

Just a question, but has anyone have a BOM put together for Mouser or Digikey? I prefer not to recreate the wheel if possible.

Thanks.

0.1R / 5W

... or the the MPC74 series from FUKUSHIMA FUTABA. The MPC74 (5 W) and the MPC78 (2 W) are declared as »Audio Grade« with low distortion, non magnetic and noiseless: Height 18 mm (± 1.0 mm) / Length 14 mm (± 1.0 mm) / Thickness 5 mm (± 0.5 mm) / RM 9 mm (± 1 mm) / R ± 10%

 

[waeah]

Too late to get in? I'd like two pcb's

 

[kpsthakur]

Quick one can we use MUR160 diode in place of BAV21?

 

[shaan]

The high junction capacitance of MUR concerns me a little. This is not a linear characteristic so best to stick to the 4pF BAV.

BAV21 not available at most places...any equivalent you can suggest

 

[shaan]

1N3070, 1N458 or any diode in a DO35 glass package with more than 150V rating will do.

 

[reaper996]

Can anyone in the US provide a suggested torodial transformer for this build?

Thanks.
