  • PSU unit spectrum 128k +2b 6 pinout DINHello everybody! I have spectrum 128k +2B but I don't have the 6 pin PSU and I can't find it anywhere. Can you anyone tell me where can I buy this PS…

    [QUOTE=zxbruno;426408]I'm not an expert, but I would say yes.[/QUOTE]

    yes you can. my +3 psu has failed so I now use an AT power supply (actually my bench PSU now as I drilled the case and added terminal posts for the different voltages)

  • Spectrum 128+ (No TV picture)I got a Spectrum 128+ which is not generating any picture. I checked the TEA2000, and it gets not 12 Volt, but only 1.4, so this is the problem, I gu…

    So the TIP31 is not really a problem, i will twist pins 1 and 2 and place the TO220 package on wire somewhere else.
    Just made myself a quick tester with five LEDs to check all voltages at once. I have much more Spectrums with missing voltages.

    Does not look like coming from Spectrum to me. Other than the internally generated voltages +12 and -5, the +5V coming from 7805 must be within the official limits (say 5%) and 4,16 is far too low. Did you solve that?
