Where do I even start with diagnosing and repairing this... #VintageElectronics

Hi I'm 90s Script Kiddie, I grew up online. I do #devops and #automation code stuff for my job. My hobbies are #gamedev, #vintageelectronics, #gaming, #repair ing stuff to keep it out of the landfill, old #apple hardware, #linux admin (I run my own mail, web, media etc servers) #network admin especially #pfsense, I love #books, #anime, #manga - reading in general really. #music too! Jazz, alt-rock, pop, folk, chiptunes... I also enjoy #cooking and am trying to get better at it. Beliefs-wise I'm something of an anarchist, yearning for a #solarpunk future I'll probably never live in, but I do what I can to do #mutualaid for the people in my circle. If you're my friend, I will set up all your electronics for you, replace the battery in your phone, give you some free mail or web hosting... whatever! I try to limit my consumption of news media for my own sanity, but I love reading about what people are doing in their own words. That's why I love the Fediverse, and it's why I'm lurking around on #gopher

I don't have a lot of friends. I've always been kind of a loner, and a little awkward. Luckily, I love my own company and have no problem spending time alone. Those few in my circle are people who I think make the world better by being in it.

I'm a #queer #bi #enby and I don't really give a hoot about what pronouns you use for me. Actually, I sort of feel like however you labeled me I'd want to break out of that box somehow. I guess I'm pretty contrary.

New #introduction who dis.

Ok #vintageElectronics nerds! tell me about these things…

The “MR” designation denotes some kind of diode (it stands for Metal Rectifier, a notation hangover from before silicon/germanium diodes) and they’re obviously arranged as full bridge rectifiers

They’re in a PSU made for the British Post Office in 1972

The brown stripe seems to denote the + end, but what does the other stripe mean?

Ok, I had to open it. The radio license sticker says 9 April 1951, but it isn't readable on the photo.

The radio has four tubes, and I'm pretty sure the four devices on a row on the left are the rectifier diodes. (Edit: nope, they're adjustable capacitors.)

It also seems to have 110V mode. 😊

The back side cover of a 1950s AM radio. The radio license fee sticker and the sales price is visible. The radio cost 305 NOK, and the license was 25 NOK. The date is not visible on the photo, but it says 9/4/1951.The inside of a 1950s AM radio. The backside of the speaker is visible on the right, and the tuner on the left. The rest is a circuit board with two tubes in the foreground and tubes, transformers and resistors scattered around in other positions.The inside of a 1950s AM radio.

So, I was bored and figured I'd replace the backlight sheet for an LCD screen in an old 90s sampler. (I'd ordered the replacement in 2023.)

Boy, that was annoying!

I had to completely detach the metal bracket that snuggly presses the LCD screen and 2 zebra strips to the PCB; so I can desolder the old and put the new one in.

With all PCBs bare, I had to turn on the machine, and adjust and move the LCD until the 4 rows of text actually made sense.

Photo of the display when machine turned on. It shows the software version "ESi-32, (c) 1997 E-mu Systems, version 3.02"

Originally green, but now sporting a blue backlight. 

The characters are a bit faded though but that part I haven't got a replacement for. Or perhaps I do, but I need to pull the thing apart again, so I'll look at that in another 2 years LOL
