Some charlize/smps questions

Code · 7th April 2006, 09:54 PM

Today i received a Charlize, I have it set up with the SMPS PSU from Decibel Dungeon

My first query is about the 10000uF capacitor on the PSU outputs. I have fitted a cheap 'Jamicon' cap as its all I have

. Is this capacitor necessary? And would there be a noticeable improvement from using a higher quality Panasonic for example?

The second problem I have is with the 10 watt 10 ohm wire wound resister on the 5v rail. It is getting very hot, too hot to touch.. is it ok?

Finally, I'm trying to decide weather to change the input caps tonite, or to wait until it is fully 'burnt' in. The caps are 2.2uf Obligatto.

Thank You

The Jamicon should be fine for this purpose. I see no reason to do away with it.

You would be better with a aluminium clad resistor with built in heatsink. I use 25w with no problems.

I would leave the input caps till the amp is fully run in. Otherwise you will never know if the big Obbs are an improvement or not.

ahhh they look excellent

thanks alot.

Is the 10k cap actually needed? If not i'll give it a listen without.

The power supply was connected the wrong way around on my charlize.

Is it repairable?

I'm very sorry for you, that's not fun and I can't answer your quenstion either. I have on for you though. There's some 50 posts covering topics about the Charlize. Couldn't you post about your wiring there?

Sorry about that

I already have replacement chips, i just need to know if thats all that should have died. And if it is i will take it to a profesional

Hi Code,
How do your caps look? I'd worry about those, but being unfamiliar with that amp design I will defer to an expert if one pops up.

I don't see a problem with posting about a blown up amp kit. A straight cap question may have been covered before in another thread. The search function is in the middle of the top right bar of buttons.

there is no visible scorch marks or leaking, everything looks as normal.

I admit I'm too lasy to search but do you have a schematic or URL that points to it?
