Those Molex will fit 0.200" hole spacing with 0.060" PTH. I know that because Valery installed those Molex connectors onto the SlewMaster OPS without issue.
Do either of you have a Mouser or Digikey part number for the actual 2 pin male and female parts? Search as I may I cannot come up with it.
Thanks, Terry

Hi Jason
Great initiative... love your work...
Sorry to throw a spanner into the works at this late stage. Could you think about bringing the MOSFETs closer to the centre line so that they don't extend beyond the board edges.
3" (75mm) heatsinks are readily available so it would be great to have an option to use these. My main issue with the Slew-master/monster OPS is that they require large, expensive heatsinks, which in turn need to be housed in large, heavy, expensive cases.
I would keep it simple and leave the cap multiplier out.
Terry, I will find you the part-number - will take some time.
For example, 538-39-28-1043 is the mouser code for a 10-pin plug of the same time, we just need to find the one for 2-pin.
Cheers,
Valery
Looking at the layout, it looks like if we move the G2 via things could be shifted enough to move in the output pads
Thanks.I have been searching like crazy but I just can't find it. I never use that type of connector but the only solution I see here would be just soldering in wires and I really don't want to do that.
Here's the Mouser part numbers.
538-39-28-1023 2 pin dual row header
538-39-01-2020 2 pin housing
538-39-00-0078 16 AWG terminal
538-39-00-0060 18 - 24 AWG terminal
Perfect Jeff, thank you!
Those are the ones.
P.S. I will be in Amsterdam till 17-th, but online most of the time. Exibiting on IBC2014 😉

Thank you. I will see if it is reasonable to make the output devices completely under-board.
OK, I see my folly now. I was looking at pitch instead of row spacing. Very confusing.😱
I'm not sure I like this method. Those plugs work out to over $1 each. I guess with the close spacing I am kind of locked into it. I'll get enough for one board and take it from there.
I just got notice that my boards have shipped so I should see them within the next couple of weeks. I should have all the parts by then too. Then I guess I will need to learn some programming.
Blessings, Terry
Do the bias connections of the protection circuit hook onto an emitter resistor of the amplifier output stage or is there some sort of current shunt added?
They hook onto the OPS emitter resistors, being optically decoupled from the protection board.

Terry, I actually buy Chinese clones through the trusted local supplier - they are much cheaper but still good quality (at least the ones I buy). Probably worth looking on ebay or something...
Thanks. Also wondering if R10,11,24 & 30 need to be adjusted to match the amplifier?

They never ship to Canada!😡
You're right - those may be adjusted according to required triggering current.
