Excuse me for this comment, but I think your PCB's for the Mongrels are quite big. They could be much smaller, IMHO.

Thanks,
I have not really listened to it (just with small test bookshelf speakers), only looked at the signals to the Scope.This evening I will connect it to the main speakers, after will know how it sounds....

OK:
- Dual DX Blame ST amp module and power supplies by Carlos Mergulhão, TO-3 outputs;
- LS Protect by Miguel Nabuco, idea from SiliconChip magazine;
- SoftStart adapted from National application idea;
- Transformers from Toroid do Brasil, 26+26ACV, 208VA;
- Fan controller from Giogros Lazaridis' idea, enhanced by AndrewT's suggestions;
- Case from Naoko (Brazil, mod. RK-2U-B);
- My design!!!!
Cheers,
Max.
Cool. I have spare DX boards to make another amp Lol.
Will be using your fan controller design and soft start.

posting images
I know this is a very silly question but I am no computer whiz. How do I post images? I would really like to share some of my projects.

Too add a photo,
First click "go advanced" in the box below the "quick reply" message box. Doesn't matter if you decide half way through a message to do that, it carries it foward.
Then click "Manage attachements"
Click browse in the first box at the top and find your picture. Repeat for any more pictures.
Click upload... a message appears "uploading"
When complete, scroll down to the bottom of page and click "close this window" or click same at top right.
The pictures should now be attached and when you post will appear. I don't think they show in message preview... they never used to anyway.
Make sure your pics aren't too big, a couple of 100k is plenty, and many object when they are massive and it alters the margins
It tells you in the attachments window what max sizes are allowed.
Here some pictures from the Supercharged
Yes, the heatsink solution is not the best...but it is the one matched my enclosure.. i am waiting some power resistances to arrive from part's supplier.
Black cable over the heatsink are for the peak meter in development... the left hand one is already in operation...but not finished yet.... rigth side one will go to the enclosure tomorrow.
Golden input connectors are missed too, also input switching and high cut potentiometer.

Carlos
