Okay, I've got two things to post.
1. Answer to the above and 2. the progress so far.
1. The cap kit response:
All the cap values have already been released here (it’s accurate):
https://wiki.preterhuman.net/SGI_Indy
However that doesn’t give you: Radial Diameter, Lead spacing, height restrictions, Original Series/Family migration path. I’ve invested a good amount of time & money, just in this one PSU model, I have like 8 more types to go for other SGI stations. Also you really do need several additional tools to free the caps from their locations.
However, I give the average person about a 40% chance of changing all the caps correctly. There are three clusters of glued components that most people will ignore or give up on (skipping them) due to hassle. That will likely lead to failures after rebuild. You have to melt your way through the existing stabilizer and use forceps or the like to remove several of these caps.
I had intended to include a required/recommended equipment list and possible pictures of the trouble spots and advice on all the removals.
If someone just takes the values from a list and buys whatever random cap, I’d give the chance of success an even lower possibility due to the improper use of low-ESR caps. Most modern caps are incorrect for this platform and may either fail to work or cause odd side effects. Indy PSUs do not appear to have ANY management IC, so the oscillation is done using passive LC components and some transistors and op amps. So correct ESR may even be more critical.
My research had to do with extracting the OEM caps and finding their identity, then finding their upgrade series using the manufacturer’s series charts over two to three generations. Not too hard but not too easy.
In order to even help people increase their chances of success, any pre-made cap kit will include some pictures and advice on disassembly. Without both, the chances of success are so low, it would likely produce a wave of failed PSU rebuilds, destroying many PSUs, or at least a wave of PSUs requiring additional work (adding to cost).
As it sits, I’m not even totally sure I want to do a Cap kit as just replacing caps doesn’t guarantee your “bad PSU” will work.
Until I recoup some sunk costs and find a way to address my concerns, I’m not willing to publish my cap choices, even when supplies are back in stock by the end of the year (est Dec-Feb timeframe on DigiKey and Mouser) if I were to sell the resultant choices, someone with enough knowledge will eventually determine what they are and then publish the manufacturer/series/values combo. Unleashing clone kits.
As it stands, I’m still in the fence about this. In one corner, I do want to see people successfully get these running again, but in another, I ran into issues (not related to caps) on several PSUs and it takes time to try to solve. Even just recapping could put the system itself at risk of the owner cannot correctly bench load the PSU to test before hand in a safe manner without damage.
These Indy PSUs are so cheap in the used market that their not practical to send for rebuilds for most people. At the same time the moment I put out any real list or kit, their will be those that jump on it and don’t realize the job ahead and ruin their power supplies. Some guidance is required get a chance of success from anyone who’s not done this before.
I can also say now that I've done three Indy NIDEC PSUs now, and there is general rule. If your PSU works now, recap it now. If your PSU worked when you put it away many years ago...do not try to power it on at all, and recap it, then try it. But any PSU that currently doesn't work will still NOT WORK when you recap it.
Once the caps go that far out of tolerance they can take other things with them! So far I've not had to replace any main MOSFETs and diodes (just one auxiliary MOSFET) so parts have been simple (but I keep having to do orders as I discover additional components). However the Indy doesn't have a dynamic management system to suspend operation due to over current and voltage and such, fusible items just go pop! Newer PSUs have some ability to do this, but not one this old! So if your Indy PSU doesn't currently work, it's more than caps!
Without a desoldering gun, proper soldering iron, and a 400F knife-tipped soldering iron to melt through the adhesive, you will not be able to successfully perform this recap due to several thing the manufacturer did that get in your way. I've got it down where I can do an Indy Recap in 45 minutes, down from 2 hours, when I first started due to the stabilizer the manufacture just poured everywhere.
2. Progress on the rebuilds
I have just finished major repairs on another Indy NIDEC PSU, after recap the PSU didn't turn on and thermal imaging didn't show any signs of life. I used a working Indy PSU (that I just recapped) as a comparator and used a curve tracer to scan every semiconductor and major path on the two boards that make-up the Indy PSU. I found one blow 500mA glass fuse, once shorted MTA4N50E MOSFET and a out of spec (R5) 100K Ohm resistor. I also managed find a great (small) little company in California called Freelance Electronics that actually had this MOSFET (as it's not been made in 20 years and I didn't really want to use the substitutes I found). Prices were very good (inline with similar parts) and while they didn't have many, I purchased a few additional units for the future. I may go back and purchase more.
I also have a failed power-on/off micro switch on this PSU that I need to unsolder and try to research a replacement!
Yes I bought extra parts for the next PSUs I do, but with the current caps being backordered I have only one more kit with of parts before I 'm out of Caps and cannot get most of them until another batch is run from Nichicon / United Chemi-Con. So this project will halt after one more build and I'll be forced to move onto another PSU due to parts shortage until December or February time frame....wish I could buy them but DigiKey, Mouser, Arrow, etc are OUT of these parts.
I have a stabilizer Adhesive I need to a fix the components in place but since i have to open the tube of stabilizer I need to finish the last of the Indy PSUs before I open it so I can perform the work on all four PSUs I've fixed before the tube hardens and such.
This part shortage really stinks because I now know what I need, but cannot obtain it. So I'll have to wait and place a huge order at the end of the year.
My hope is to move on to TEZRO PSUs as they use more modern parts, I hope those caps will be more widely available because they are likely lower ESR caps (no need to conform to vintage specs). I've not been inside one yet but I have a spare on I'm going to start with. I have to rebuild three Tezro PSUs to get everything going, so hopefully things will be good. I'll make a new thread for the Tezro PSUs when I start.
NEED ->
