Re: [TCML] SISG Boards+Parts for sale

Dan -
 
Not sure if you are aware of this, but the 300 volt SIDACs required to complete two of your three boards were discontinued several years ago, and are nearly impossible to find.
 
Unfortunately, the FGA25N120 IGBTs are not suitable for use with these boards because they do not have an internal anti-parallel diode.
 
Also, the auction description states that SIDACs are included for two of the boards (24 SIDACs would be required), but the photo shows 12 SIDACs, enough for only one board.

All,
I have 3 unused Mark Dunn SISG spark-gap boards for sale, along with almost all 
of the parts required to build these boards, including the IGBTs. All that is 
missing are the resistors and the SIDACs for two of the boards. Everything else 
is included: heatsinks, mounting hardware, transorbs, caps, diodes, screw 
terminals, SIDACs for one of the boards, etc. Please take a look at ebay auction 
# 150612733367 for pictures of what comes with these boards if you're 
interested.
Thanks,
Dan
