    They did come with the original commodore internal shielding in the UK.
    Its common for users in the UK back in the day to remove the upper shielding because it was cheaper in the early 90's to squeeze a 3.5" IDE hard drive into the A1200 and you had to leave the upper shielding off to close the upper plastic case, with a bulge, after fitting the HD.
    I have my original 1200 from 90's without its upper shielding, lost in time after I removed it unfortunately.
    I have 2 other 1200's, one modded with no upper shielding and one stock that still has the upper shielding still intact.
    As a comparison my A500 and A500+ both have there original shielding, rusty but still there.
    Any other 500's I have handled/repaired have had their shielding still intact.

    I'm from Portugal, and all my five amigas came with metal sheeting:
    A500 and A600 bought locally
    A full Rev2 A1200 bought from the UK and another Rev1 (only the motherboard, that I use in an old PC case);
    A CD32 bought from the UK.
    Only on the CD32 have I kept the shielding after recapping it.
    For the others, due to the expansions, I've removed the top of the shielding (they are in storage, just in case one day I need them back).
    As far as I know, there were no A500, A600, A1200, or CD32 without the full metal shielding.

    Hi Chris, thanks for another fine video from you. I have 2 points I want to mention. By the keyboard connetcor you can lift the top connector part, or take it off if you are not afraid to break it, and that will give you 2-3mm more space to operate in. I belive you have never had pad damage from snipping, but if you make sure that you snip from pad to pad on the capasitor, then you will releif the stress on the legs - I can see in your video the the legs are bend a bit from snipping stress and that can be avoided.

  • @tlaskows
    @tlaskows Год назад +1

    Those metal clips on the shielding. Never solder them. Use apple repair tools to bend them to remove shielding then apple plastic repair tools to bend them back in. They can break easily. I just use a flat screwdriver because the plastic tools keep breaking just by trying to remove all the shielding.

  • @JamesHalfHorse
    @JamesHalfHorse Год назад +1

    Thank you for this. There is nothing wrong with cutting caps but most people leave out the details. If they are really skanky caps, you don't know how much damage there is under it or near something that doesn't like heat it's the best choice. Have you tried using end cutter style nippers for the ones you can't get at with the side nippers? I have had luck with them. My much missed long gone A1200 I think had a board in the trap door with an ATI labeled chip and I think a 68040. That ring any bells? I have never seen one like it and sadly never got to really get into it before I had to store it and it was... given away for me. Before I bought it in the late 90s I think it was a graphics/animation workstation.

    Haha you knew you'd get hammered for the ✂️- I've done all mine with reflow hot air but hey different strokes for different folks. This might be a time saving strategy for the caps between the keyboard connector and the rca jacks onna 600 and 1200 though - would save removing those to avoid melting them with hot air on the condition you have a skinny enough soldering iron tip to get back in there with the replacement caps.

    Thanks for showing the recapping process again! One question: I bought a 1200 (with TF1260) last year, which is said to be recapped. It actually is, as far as I could judge. BUT as I saw later on, several electrolytic caps (C459, 214, 407, 324, 334, 303, 304) were replaced with ceramics! Ceramics are NP, so might be ok with the tricky 324 and 334, but with all other polarized caps? 🤔
    The Amiga with LC060 at 50MHz works perfectly fine, no overheating components (for what I can judge), no crashes! But the bad feeling of having the "wrong" caps inside remains of course.

    • @ChrisEdwardsRestoration

    The additonal shielding on NTSC Amigas has been attributed to the stricter RF emission standards in the USA. PAL is a version of NTSC where the phase is changed on Alternate Lines, hence "Phase Alternation LIne". It is less susceptible to interference than NTSC, so emission requirements don't have to be as strict.
