Mark:

Thank you for your hard work and generosity!

All:

I'm considering making a bulk purchase of Mark's H9KPXG boards and selling them at cost to members in North America. Estimated pricing and other details can be found in the Swap Meet forum at Mark Johnson's H9KPXG LV On-Off Switch / Soft Start PCB.

Regards,
Scott

Hello,
Thanks for this awsome project. I went though ordering PCBs from JLC and parts from Mouser, which was new to me. I have just assembled one H9KPXG for myself and you know, wow it works
So now I have 9 spare green ENIG-RoHS 2 oz copper PCBs, - if anyone in Europe is interested, please p.m.

Congratulations @mcaronas!! It takes bravery to try new things but that's how we learn and grow. Very well done, and thank you on behalf of European members!

Default Thankyou

Just installed in the F6, nice to have a front panel power button.

Default another pic

Black on black inlay of the lettering may have been a mistake, but it sounds great, and now I don't have to take a knee to reach around back to turn it on. Thanks again Mark.

Looks great, angrypat! congratulations. Maybe on your next build, you might decide to offset the trafo and/or the PSU PCB by one or two ranks of holes. Accepting a small amount of asymmetry, in exchange for a lot more room to mount the H9KPXG and route its wiring.

I did that on a Cordell's Super Gain Clone build, and the visible, but slight, asymmetry didn't trigger a crippling bout of Obsessive Compulsive Disorder. But you may feel differently. Click on the image to see it full size & undistorted.

Click the image to open in full size.

edit- forgot to say: H9KPXG board is at right front, immediately behind front panel "anti vandal" pushbutton switch. Orange colored "soft start bypass" relay is clearly visible.

Just like the car mechanic tells me "new" things which I haven't kept up with as I just turn the key, drive and check oil level and tyre air pressure. Couldn't care less about cars as long as they bring me from A to B without trouble. Do I need all the knowledge? No. Do I like all the knowledge? Yes, but a man is limited in accepting again a new territory. Some can accept newer technology (or technology at all) quite fast and some just like the mystique in audio and will never fully grasp all the necessary stuff there is to know. They just like music and want to play it in a better way. Reading a schematic and following all the logic involved is too much for some. Many details in electronics are very strict and now of a sudden one can choose either a 16V or a 25V capacitor?! The logic that 5V won't harm any 16V or 25V cap is not self explanatory to everyone. That is why a BOM (DPL ) with exact part numbers is best for those that have doubts about their own capabilities or just don't know how to reduct/deduct what can and what can not be used as alternative parts. And then, you could wait for it, people will ask if they can use parts that are not in the BOM...

To some newcomers that like this hobby very much I guess we have to tell the answers, tiring as that may be. We should be glad there are newcomers at all.
excellent post - it could be part of the Forum Constitution.

I know mine is a little tight, and not as neat as yours Mark, OCD? Is that a wire stripper on left? I think I've used the same one to strip 24ga wire for telco frame work.

Great video and great looking board, djlove! Congratulations! If you ordered the boards yourself from a PCB fab, please tell your fellow European members how difficult or easy it was to place the order and receive the boards.
