NV-V8000 vcr caps change

[Thermaltake]

Hi, I am restoring my NV-V8000, and wondering there is 16V 4700uF cap near transformer, is it low esr one or normal one ? On PSU they are all replaced with low esr, but I am not sure about that one near transformer. I tried to google and look at manual but I couldn't find anything.

hard to say without a schematic.
try rubycon YXF series.
they are high temperature long-life caps with a slightly low esr without being extreme like FR or ZL's

I have Nippon KYA are they too extreme for that ?

If it's not a problem can you take a look at manual I upload it for you (it's a bit big 155MB), I couldn't find myself.

here is how the situation looks like, I will only change this big one, little ones I won't touch.

thats linear, any high temperature longlife cap will do.
but the small ones are the ones you need to replace first - they dry out faster

Would transformer perform worst or something if I put low esr on both little ones and big one ? Or it's recommanded to put normal 105C caps on all ?

I order that big one 25V 4700uF normal esr. But those little ones6.3V 47µF, 25V 33µF, 6.3V 100µF, 16V 47µF, 6.3V 100µF, and 16V 33µFI couldn't find normal esr they are all low esr.


Also there is lower board I think it's servo board (VJB06704), don't know if you saw it in manual. I assume that board is controling timings and stuff like that, and caps should be normal esr, am I right ?
