I'm looking to verify screen / system stability with focus on the Micron Xceed Grayscale card installed. Essentially a 'go', 'no-go' report is good enough at this time. If a system was found to be unstable, then I would be curious to dive deeper. My aim is to ensure that my PSU is rock...

Excellent. Thank you for confirming. What kind of hard drive are you running?

Hey All, I am getting word back from a customer that they are having significant screen flicker issues when running my new PSU with a Micron Xceed Grayscale card. The issue appears to be primarily from cold bootup for the first 30 seconds or so (sometimes more, sometimes less), but there have...

Ah, gotcha. No worries! As long as the connection is solid and everything is safe, it should be fine.

Hey Chuck! Thanks for your purchase. Sorry you had some alignment issues. I’d be curious to follow up with you a bit more to make any adjustments to my component footprints on the next run of PCBs. Just to clarify - The Sony connector footprint is designed for the original header part only...

Hey @tt - I don't have plans for a DIY version. Preassembled and tested only.

Thank you @zigzagjoe for your thorough testing! This is much more than I was expecting and am very grateful for your time and effort. You're a legend!

Hey All, I posted the PSU installation instruction video to YouTube. Go easy on me.... this is my first time making a how-to video, let alone any form of video content. I certainly learned a lot but am happy to be done and release what I recorded. I suppose finished is better than perfect.

I remember looking at that model for a single supply replacement, but its 12V output comes up short for meeting the original current specification. I decided to substantially over spec the output currents to meet needs of those who expand their system.

You bet. A number of manufacturers have PCB mount power supply modules. I have preference for Mean Well as they have never let me down and have an intersection of price and quality that’s hard to beat.

I must admit I am biased on this topic, but one of the issues I see with the Pico kit is that it relies on a DC barrel jack for the power input. These are usually rated for 5A max. I’ve seen a few from Switchcraft that are rated for 7.5A, but they are $. With a 12V input at 5A, that gives a...

There are risks and liabilities to be aware of when selling any product, and there are a number of ways to protect yourself and the customer. First, I operate and make sales under my business, Baby Face Electronics LLC. This offers some base level of liability protection as a manufacturer...

I'm a big fan of the IRM series, and Mean Well in general. I've never encountered a bad module and they always perform as you expect. For your projects, I would suggest that you reach out to them directly. The correct contact email can be found on their website depending on the country you...

The original PSUs did use the crimp terminal pins to solder to the PCB. I would argue that they are not necessary. Wire breakage has to do with repetitive movement over extended periods of time. The wire becomes work hardened with every movement, looses flexibility, becomes fragile, and...

Here is the pdf @JdM74 put together for this project. Thanks!

Hi All, I wanted to let folks know that there is a new option for SE/30 power supplies. With the help of other people in the forums, I've developed a universal drop in replacement power supply for the SE & SE/30. It is a direct replacement for all three types of power supplies - Astec, Sony...

Hi All, I wanted to let folks know that there is a new option for SE/30 power supplies. All the details can be found on this thread: https://68kmla.org/bb/index.php?threads/se-30-design-for-drop-in-replacement-power-supply.47462/

@zigzagjoe - The 12V supply is robust, oversized and appears to be capable of maintaining proper load regulation as to not affect the display. I believe there is an additional benefit to having a new wiring harness installed to overcome the oxidation and parasitic resistance of the original...

@joshc - International shipping is available via the eBay listing. I would be interested in getting additional in-circuit testing, however, I believe the specifications of the new power supply are a substantial improvement over the original. The 5V supply got a 66% increase in output current...
