Happy Birthday, Jim! Enjoy the day

I’ve been using that series for a bunch of years now and I’ve been very happy.

Happy Birthday! Enjoy

R28 and R29 are the bleed resistors for the DC output (typically 400V or 450V). R30/31 & R32/33 are for the DC input and are in series since the voltages they see will likely be above 500V. In general, the capacitor bleed resistors are set to around .4W to .45W or thereabout - independent of whether they are in series or not. They can be a bit more or less. I usually like less. Any values that get you close are fine. Just make sure they are still 500V each and at least 1W. This chip storage is mentally fatiguing... or... a great way to hone your skills. Pick one

Happy Birthday John! Enjoy

Here's the part numbers for the 2x8 connectors: 1-794065-0 770579-1 770988-1 The 2 and three pin connectors are the same series.

Happy birthday!

Congrats @jamesmking and @JoaMat! Nice work!

Those look fantastic! Congrats.

I don’t use that anymore. Just the 10K pot. Works much better.

Happy Birthday!

I did the Ocoee in a raft about a decade ago. What a great trip! Enjoy

Congrats!

On my prototype build, I had some hum issues. I tried DC supplies on the front-end and they did not help. What helped was how I routed the power / filament supply wires. You should have no hum on the T2.

At some point I switched to a 10K pot. I liked the characteristics better with the 10K pot. My newest boards use 10K pot as well.

Hi Milan, You should be using a 10k linear pot for the controller. That might be older code, but it’s been a while and it will take some time for me to find and verify a newer version. Best, Kerry

Happy belated birthday!

I send my stuff out for the moment. They use a fiber laser. Very nice stuff. Congrats and good luck.

I thought it was just stereo...

If you're having issues with a 4 amp fuse at 240VAC you may have something wrong. Make sure it is a slow blow fuse. They start with a T in front of the of the value (i.e. T2A @ 250V).

Mine also run at about 205W. I've been using T3.15A 250V slow blow fuses in the US and I drop that down to T2A for 220VAC or higher. I think these values are pretty reliable.

Happy Birthday, Todd!

Happy Birthday!

Happy Birthday Antonio!

Congrats!
