green power supply

[Luax]

Hi Guys,

Recently I fired up my Green pre for the first time.
There was sound(in a positive way)….. then there was smoke…. and then there was the sound of a china cracker going of in my room, except it wasn't a china cracker but a 10uf 63v cap on my green pre PSU.
I'm a little afraid that it might happen again if I just replace the cap with a similar one.
Has this happened before to someone?

Check your wiring and you have not accidentally turned upside down capacitor

I'll try to replace the cap first and double check it on polarity.
I think the wiring should be all right… I've done it same as discussed on the forum.
But i'm not 100% confident about it. Any suggestions what to double check for?

Is it the 10uF on the middle leg of the 48v supply?

You might need a 100v part in there

Hi Peter,

It could have been that I used a cheap component with to big of a margin. (perhaps 20%...)
A similar one that I used as a replacement is still holding it.
I might want to replace it with a 100v. To be safe for the future  8).

Cheers,

Hey guys,

Since the link for PeterC's site is down is there another link to the PSU BOM/parts list and schematics? 

It's gotta be here somewhere...

Thanks!

I just found it here:

I wanted to run this by the pro's here. The part list for the PSU estimates $20 for the 6VA 115 15 transformer, but I found one on mouser made by Hammond Mfg. that is universal 115/230 primary (good since i live in EU but may move to the states at some point) , 6VA, and 30 secondary, 15 parallel.  It's for about $12.50 but want to make sure this is a good quality transformer.

All opinions appreciated =)
