Hi Vic, congrats on your GC completion

Is that block of wood hollowed out? If so, couldn't you have got the whole works in there with front and rear panel for sockets etc? Just a thought - you know what I'm like when I see a block of wood

It's made from 3 pieces of oak boards. I made it this way because I wanted lots of mass for a base and I had the wood lying around.

Yes, I can see now Vic - three layers. Still reckon you'd have a corker if you put the amp etc 'inside'!

I would make a compartment by cutting out material from the bottom two layers and then add a matching piece of marble to make a base. Strip of aluminium for the heatsink(s) and Bob's your uncle!

Funny you should say that. I, too was thinking of using marble or granite. In fact, I was looking at 12" X 12" tiles and thinking about cutting them. I have a diamond wet saw from one of my home improvement projects. But, I got anxious and decided to build it this way.

My next project will certainly use marble or granite firstly because of the mass to reduce microphonics and secondly because I just like stone!

BTW, the amp is actually in the two aluminum boxes. The input and pot are in between in the wood.

Vic

Default capacitors

Since I am going to use batteries, I didn't think it was necessary to have the caps. Do you think it would help? The .1uF cap across + and - rails makes a big difference.

I don't know, but it's worth trying.
