I thought it would be interesting to have a thread where I could talk about what’s OBT (on the bench tonight) - or what do I have to work on. A good chance to show what sort of projects and stuff I am working on.
I also invite folks to post their stuff here if they want - especially if it involves stuff from my shop!
I know there are folks working on FH9HVX, Alpha Nirvana, SLBs, SFPs, Aksa Lender’s, Yarra’s, and Rockville speakers, 10F/RS225 TL speakers, foam core builds, etc. please share what you are working on Tonight!
To kick it off, here is what I will be doing: some SMT reflow soldering of the LU1014D power JFET (I think it is a SIT) TO-247 IMS adapter boards. These will be a test batch to check to make sure they work. There is a GB here - I won’t be running it and the boards can be ordered by anyone as the Gerbers are posted free for all to use.
Woofertester has sent me a batch of matched LU1014D’s to install on these boards. These aluminum substrate boards will allow these peculiar power JFETs to be mounted in an underhung fashion like a conventional TO-247 MOSFET. They should be much easier to use. Also, Nelson Pass is giving away a bag of these unobtanium SITs to they DIYA community. Woofertester is doing the matching and WG45 is handling the GB. Thanks to JPS64 for the awesome layout of this metal substrate adapter board. Thanks to Nelson Pass and Woofertester for the LU1014D’s, and thanks to WG45 for handling the GB that is off to a roaring great start. I can’t believe we have 101 pairs of these adapter boards on the interest list already!
So that’s What’s OBT for me.
What’s OBT for you guys?
