gs80065xe Posted April 4, 2020 Share Posted April 4, 2020 I've had my 65XE since the late 80's. And I've never recapped the machine. It uses a rebuildable power supply I purchased from Best-Electronics a few years ago. In addition I have a restored 800 I purchased off E-Bay. But I don't know if restored means it was recapped. It appears to be using an original 400/800 power supply. Since replacement parts are becoming more scarce, I was wondering if there are any particular caps I should replace just to be on the safe side.

gilsaluki Posted April 4, 2020 Share Posted April 4, 2020 65XE. If it boots up and there are no power, video, sound issues...why F with it? If you want you can inspect the caps. No leakage, no bulging....why F with it? 65XE motherboards can still be had, not a rare thing at all. Leave it alone, unless Corona (the Virus or the brew) has you bored.

Caps are not going to be hard to find ever, so I wouldn't waste my time unless you are having some issues with the machine or you see some caps bulging. When I do a re-cap on a CRT I replace every one of them, they are typically cheap. Best, Gavin Quote Link to comment Share on other sites More sharing options...
gs80065xe Posted April 4, 2020 Author Share Posted April 4, 2020 OK. I was just concerned about their age and drying out. Didn't want to risk one failing and taking out hard to find components with it. Quote Link to comment Share on other sites More sharing options...

Didn't want to risk one failing and taking out hard to find components with it. Kind of seems to me that it depends on the systems if the caps tend to go so bad they need replacing. For example, most of the STs I've seen, no cap issues. Amigas, almost assuredly have issues that a re-cap fixes. I recapped the 7800 I have that has a cracked case... and I don't know what I did, but the new cap is bulging for some reason. Guess since I just bought this giant bag of capacitors, I could replace that one again... Quote Link to comment Share on other sites More sharing options...
Colleton Posted April 5, 2020 Share Posted April 5, 2020 I bought into the hype (and got bored sitting at home for several weeks) and recapped all of my 800s, a couple of 400s and all of my ST PSUs. I haven't really noticed any difference, but it was enjoyable work. Ordered everything through digikey. 1 Quote Link to comment Share on other sites More sharing options...
Rybags Posted April 5, 2020 Share Posted April 5, 2020 600/600 XL and the XEs all get their native voltage from the PSU. Any related damage is usually due to that rather than an internal failure. I might be wrong here but I don't think removing or having any internal cap fail would damage the computer at all. Quote Link to comment Share on other sites More sharing options...

You are right, the caps that go are generally electrolytic's and they tend to be there for power stabilisation, so when they go bad, it's usually the PSU/regulators that suffer. Of course a failed regulator migh then allow higher unstable voltages onto the power rails which in turn could then kill chips. Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted April 5, 2020 Share Posted April 5, 2020 Replying in a literal sense, any of the HV caps out there is still charged, seen a few of them shorted to discharge...Boy that's a bang.. As for the XE, always worth getting spares of anything getting feed from the regs...To be honest, If I had the time I'd make a complete list of components and where possible , get a couple of each as spares.

Rybags Posted April 5, 2020 Share Posted April 5, 2020 Custom chips aside, most ICs and components are off the shelf and easily obtained. Given the youngest machines are now almost 30 years old, they've lasted pretty well. I bet if you recapped an XL just for the sake of it, they wouldn't last the same duration again. 1 Quote Link to comment Share on other sites More sharing options...
Gunstar Posted April 5, 2020 Share Posted April 5, 2020 (edited) The most "dangerous" caps are the ones leaking or bulging.? Of course they all could be dangerous if you try biting them with your teeth...but mostly they keep to themselves and don't bother anyone. I've never had one try to mug me or threaten to blow up in my face or anything at least...? Edited April 5, 2020 by Gunstar Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted April 5, 2020 Share Posted April 5, 2020 My area is so rough the caps attack you, also been mugged by a 47K resistor.. 1 Quote Link to comment Share on other sites More sharing options...
