Hi Lasy Cat, i have a bunch of MJL3281/1302 laying around. I take a look at SC5359/SA1987 datasheet and they seems to me to quite near on MJL characteristics, only toshiba cob is 360pf as Onsemi cob is 600pf the reste is quite the same. Do you think they could be good candidate for SSA BIGBT?
I have a pair of 300Va 2x25V laying under bench as a pair of 200x200x40mm heatsink too. These could be a good begining for SSA BIBGT Regards Marc

Hi Alex.
May I be bold to ask that you publish Gerber plots as well for those who are making professional boards. Just zip them up and post them with the PDFs. The layout is very, very nice, thanks Alex. Kind regards Nico |

It would be great if Alex prepare an extra PCB for all-japan bjt devices with respecting Nico's circuit.
I wonder why all pcbs have power supply unit? Is there reason for that amplifier should be close to power unit? If it is not mandatory, PCBs should be bare in my opinion. Last edited by terranigma; 26th August 2011 at 11:18 PM. |
