Thanks for your suggestion, but I've read numerous warning about buying capacitors off eBay because of all the fakes being sold. I'm not saying all sellers there supply fake ones but you never know, so I want to buy them from a trustworthy dealer instead. I'd rather pay a little more and have peace of mind and not risk having to recap in the near future again..
I'm going to order low-ESR capacitors from
Panasonic's FR-series (as Exxos has mentioned he's using
in an earlier posting. He specifically mentions the FR-series
in "NOTE2:" at the top of this page) with a 10000 hour lifetime and 105 degrees C rating, with the values he suggested for this particular PSU (
PSM-5341) I've added the capacitor part no. on the PSU PCB.
400V 120uF - Replacement 150uF 400V (C6)
400V 10uF - Replacement 10uF 400V (C7)16V 1,000uF x 2 - Replacement
16V 1500uF (C15, C16)10V 2,200uF - Replacement
16V 4700uF (C14)16V 4700uF - Replacement
16V 4700uF (C13)10V 680uF x2 - Replacement
16V 1500uF (C17, C18)10V 100uF - Replacement
10V 100uF (C19)22uF 25V - Replacement
10uF 50V (not a typo!) (C23)3.3uF 50V - Replacement
10uF 50V (C20)4.7uF 50V - Replacement
10uF 50V (C26)25V 100uF - Replacement
220uF 50V (needs to be mounted higher due to resistor in way) (C8)25V 220uF - Replacement
220uF 50V (C24)Finding 400V caps with the same lifetime rating (10000 hours) as the other capacitors was difficult (marked in red in the above list), but I finally found something suitable. Not 150uF as Exxos has listed above though, but 120uF (the original value).
Exxos, if you're reading: would this cause a problem (interacting with the new replacement values for the other capacitors) or will 120uF/400V (C6) still be fine?So, to complete the list above, here are the two final capacitors (the ones marked in red above) I'm going to order:
120uF/400V (C6) replacement:
120uF/400V Rubycon BXW-series (12000 hours, 105 degrees C) (C6)
10uF/400V replacement:
10uF/450V Panasonic EE-series (10000 hours, 105 degrees C) (C7)
I've discussed recapping in my
Mega STe repair thread as well as there wasn't much response here.
I'm attaching a schematic of the Phihong PSM-5341 below, where I've added the component values (with changed values according to
Exxos' new values) in bold.
And here's a BOM of the parts you need to buy (same as the above list, but with the total amount of components of each value).
NOTE: it just occured to me that I haven't included the physical dimensions (height, diameter and pin spacing) which is important in terms of the parts fitting inside or not. Fortunately
Anodyne posted an attachement earlier in this thread for his TT power supply (apparently the same PSU used by both the TT and Mega STe) which includes that information.
