It looks like the power supply that arrived with one of my Lambdas.
I don't use it, as it gives the bad picture on the monitor, so it becomes unreadable.
I just use a cheap universal power adapter where you can change connector and these voltages 3V 4.5V 6V 7.5V 9V and 12.

Aaah, so it's a know problem with these old power supplies?
Yes, it's the power supply that came with my Your Computer 2000.
Would a ZX Spectrum PSU also work or is the polarity wrong (or I can messure it when I get home ...)

Spectrum power supply has wrong polarity, so stay away from it.

I purchased a new PSU but the (RF) image did not improve.
I also managed to get a picture over composite (the monitor output) but it lacked colour. But at least I did get an image ultimately!

Also I found a NOS 16K ram module

I will leave it at that. The Lambda 8300 and Basic 2000 and all peripherals will return to the shelf now.

Great to hear you got a picture. Sad to hear there was no color.
