Hello all.. this is my first post at lowyatt. tongue.gif tongue.gif

I own a 4ch Beta22 which was built by Indonesian amplifier designer psychaudio. At the moment I'm also troubleshooting an SSMH amp which a friend of mine, ian_trooper built. It sounded awesome for a while, but then it goes kaput! I dismantled everything, while at the same time am sourcing a better case for it. smile.gif

My DIY skills mostly revolve around breaking up stuff and making my own cables. tongue.gif

Hello ting.mike!
Welcome aboard! biggrin.gif
Keep us posted with your troubleshooting progress.. we could certainly learn a thing or two from your troubleshooting work..
I started the same way too! biggrin.gif
Do you have your own blog to share?

Hi Jazzy,
I suck at trouble shooting.. anyway psychaudio pointed out to me that one of the resistors, R2 (or R8, can't remember which channel it was) blew up. I really am not sure what caused it. Silly me, instead of just replacing the R2, I went and dismantled everything. doh.gif doh.gif
Actually I really want to get the SSMH re-cased in a nicer enclosure, since the only thing preventing me from using that amplifier more is the crappy 1/4 jack and case my friend used to build it. tongue.gif

So, now everything is dismantled. It'll probably be a while before it's back and running. I have to make time to get some resistors first. tongue.gif

The next time I build it, I will use a bigger heatsink for the mosfets, since the default heatsinks run way too hot. tongue.gif

I don't have a personal blog, but I am working on this site called www.headfonia.com. Please go easy on the reviews though, as I'm quite a noob when it comes to doing reviews. rclxub.gif rclxub.gif rclxub.gif

Hi!
Take it easy, one step at a time.. wink.gif

Dismantling is EASY work.. we can get carried away..! Hahahaha..
MOSFETS are heat monsters! Make sure you satisfy the heat dissipation requirements.

headfonia? Will have a look! Thanks.

Have fun!  biggrin.gif

OMG... F5 in malaysia?

I bet there are many F5s in malaysia. I've got two myself. The F5 in my desktop keyboard and the F5 in my laptop keyboard. My wife's laptop also has an F5 I suppose. whistling.gif whistling.gif

Hehehehe... wonder how the K1000 AKG sounds out of the F5.

That's a good one. rclxms.gif rclxms.gif rclxms.gif

LittleGhost, I notice that you design and build amplifiers. Just want to ask though, is there a good source for portable-size hammond casing in Malaysia?

Yes, the Hammonds aren't cheap.. only good amps should be put inside. biggrin.gif

I found a good casing for the SSMH, but the top and bottom doesn't open, only the front and back. Bummer. Pretty hard to do point to point on that box. tongue.gif
