Bench power supply upgrade
Ancient history: When I was in school about half a century ago someone put me in contact with a widow who wanted her late husband's electronics stuff to go to someone who would get some use from it. One of the items I bought from her was a Heathkit EU-41A bench power supply.
A few years ago it stopped working. I wasn't doing a lot of electronics at the time so I put it aside to see if I could fix it later.
Recent history: Last year when it became apparent that I was actually going to have a place to work on electronics I started thinking about the equipment I would need and I bought one of the 30V 3A "red" power supply kits that are all over eBay but before it arrived the weather had warmed up and I was working in the garden and the garage so I put it aside for this winter. One if the summer's projects was re-organizing the garage shop and when I came across the Heathkit it occurred to me that putting the new kit inside the old case should give me what I need.
I also have a digital voltmeter/ammeter that I bought for another project and didn't use so adding it to the front of the case will be a definite upgrade.
Here's the Heathkit before I start taking it apart. I will have to dig through my box of knobs to see if I have anything better or whether I need to order some.
I had been hoping to use the original transformer but the first thing I noticed when I took the covers off is how small it is.Then I realized the EU-41A's maximum output was only 15V...
