hmm.. looks like I should just order 50 boards.

Alright, I'll start putting the panel together, and hopefully order the boards in the next week or two. There's a one week turn on the boards, so that should give a rough timeline on when these will ship out.

Regards,
Owen

From a few days ago on the last page:

thanks hochopeper, correct I simply dont have the time, my business needs the time and I figure I gave enough to it last time. Each fet requires 10 mins or just under plus initial setup of the rig (which has been packed away), it needs this whether the fet makes the grade or not; and data entry, sorting, packing....

multiply that by 100-150 and.....measuring gM at the circuit operating point is not like measuring IDSS. I have posted my method if people want to do it, but let me warn you it is not a task to be taken on lightly, as I did when I agreed to do it the first time. even with full on measuring gear, or a curve tracer.

the cutoff was before that post, as well as Ian as I had already mentioned to him I would sort him with a set. i've got a heap that I already measured but didnt make my grading last time and another 100 or so that havent been measured, given my parameters were more than 100x tighter than what Nelson mentions for his power amps I might find more sets by loosening the requirements and charging less for them, but i'm not making any commitment; the whole scenario was a nightmare last time and I swore to myself I would never do that again.

qusp:

It's funny how time heals all wounds... I swore I'd never ship another PCB, and yet here we are with another run of 50 NTD1s.

I'm secretly hoping a few people in this group want to do a nice chassis for this, as mine is still a mess of wires sitting in the back of my stereo rack. I have a design, I just don't want to spend the money on a one-off chassis like that.

Cheers,
Owen

Don't keep those chassis ideas secret Owen!

I could certainly be convinced, need to have plenty of space for ancillary gear though or a matching psu enclosure.

Hi Owen

Will this China made chasis meet your requirement, only cost $50. All alumimum including heat sink at both side.
