thanks again for looking into this :) the MIEC caps don't have any series on them, here is the only text they have printed: http://i.imgur.com/ToQAzPc.jpg I do believe at this point that they put Panasonics in crucial parts and whatever crap they could find for other parts... AFAIK the giant/elgen …

Evert just let the psu discharge, I don't think you'll have a problem I also uncovered the ICs under the heatsink on the jamma psu: http://i.imgur.com/summ1Qe.jpg Regarding the meter, it's a simple and cheapish one - not the cheapest but nowhere near the price of the good 800+$ ones... more like 1/ …

^ see this PDF that is the schematic this thing is made of: http://www.mikrocontroller.net/attachment/164956/ttester_eng104k.pdf , at page 40 , chapter 5.3.4 it goes into detail about how it measures ESR . I can't tell if it's a good way or not. edit: excellent again! Thanks PCBONEZ , I'll follow …

built and tested , no need to look further - need to also build the separate h+v sync combiner to get all the needed signals http://i125.photobucket.com/albums/p55/restqp/A500-%20XT%20build/k-cga-to-scart_zpspvagjbgi.png http://i125.photobucket.com/albums/p55/restqp/A500-%20XT%20build/WP_20150827_ …

excellent! These caps in the picture are all in stock , apparently we are getting UK stock. All check out for immediate dispatch here. I get the greek edition of the site - there is no local stock at all but a fixed 5eur shipping fee from UK _or_ free if you wait ~10days and you pick the order from …

Thanks so much, I did not get a single Panasonic option but I only looked for the same voltage ratings since some caps are related to image adjustments and didn't want to fluctuate from the specs much (hopefully). Then again I did not look at the low impedance category, I just searched in "105°C THT …

Thanks PCBONEZ , yeah it was in a horrible state... the before picture is actually AFTER a first stage cleaning with compressed air and a paintbrush... The caps I chose are ofcourse 105˚C - no point in getting 85ers nowdays I think... Here is where I am thinking of ordering: http://www.tme.eu/en/ …

The main problem with EU 1084s is that they don't support NTSC over composite... TTL will work fine (I have a 1084S-P1 now and it's great for ttl/cga) but you might as well forget the composite output with a PAL 1084. Even with a gaming composite ntsc->pal60 converter you won't get a good picture - …

totally unrelated to PSUs but I am in the process of recapping an arcade monitor (well... it does have an onboard PSU :lol: ) http://i.imgur.com/Adryq5r.jpg http://i.imgur.com/2wIgruC.jpg http://i.imgur.com/pi0aeQj.png It uses a mix of Daewoo RSS/RS , Chemicon SMG/SME and Samsung GL/GH capacitors. …
