Hi All, Soldered the first lot of 4 pcbs of Sync rectifier with all components. Tested with 12 v transformer . Got around 16.1v on the output with a 10mF capacitor. With a test resistor load of 48ohms the current would have been around 330ma. Great start for me with learnings on soldering smd device. Any views on the max current that can be drawn with this sync rectifier board without stressing the components? Cheers! Ravi

Hi James, Pars, Thanks a lot for the tips. Will try again and report back on progress. Cheers!

Hi Kevin, Tried to upload the above files to PCBWay to order but couldn't . Any tip to do this will be appreciated as I am not familiar with GERBER or other file formats and this is my first go to get fabrication done. Cheers! Ravi

Very nice build Leve. The VCaps will really let the sound bloom after some time. I hope to start the case preparation for my build this week end. The boards need just one or two more bits I begin testing.

Hi Leve, Thanks for the reply. Located the 3900pf piece. Using the reference provided the 1000pf cap comes up as a ceramic disc cap made by Murata and indicating obsolete. Yes, I can that disc space is limited, but may have to think of a different way to locate if it does not fit. Cheers!

The 1000pf and 3900pf 1000v capacitors for the psu board are listed as obsolete with mouser and digikey. Has anyone tried alternatives such as metalised polypropylene caps of the same value? Can it be used? The one I have tentatively shortlisted are shown as useful for high dv/dt apps. Appreciate some guidance on this. By the way, I have installed stn9360 using small conversion pcbs instead of 2SA1486, as the 2SA1486 lot I had purchased all topped out at around 310v on the transistor tester.

If anybody is interested in an used T2 at eye popping price, please see the link below http://yahoo.aleado.com/lot?auctionID=j401791916 Cheers!

Hi, I would be interested in a set of boards. Ravi

New member here. Pl pm me if anyone has a set of boards. Upgrading to SR009 after living with 407/SRMT1 combo for 7 years.

Hi, Do you still have the board sets? If you do can you please check on postage to Wellington, NEW ZEALAND and advise? I would like to purchase one set. Cheers! Ravi
