Default YAY - finally finished my first gainclone and cases - pics too :)

Having been inspired by some of the superb craftsmanship I have seen on these pages, I have recased my amp and tried to make it look nice

The amp lives in a 19" 1U ex network switch case and the PSU lives in a 19" 2U case from Maplins (which is very poor quality for 40 BTW!!! - that'll be replaced sometime... Maybe I'll make a case from scratch if I feel brave

Anyway - thanks to those who have designed and produced the kits and to those who have inspired me to make it look nice (IMO) too.

I have used the same wood as I'm using for my speaker baffles so it should make a nice set.

I got a 1/2 inch ally bar and milled out places for the chips with a router - it was dead easy TBH but the bit suffered slightly.

The heatsinks are glued at the edges with epoxy and have heat sink grease in the middle - this has always worked fine for stuff I have done with pooters and is an easy way of attaching them.

I still have a bit ot tidying up to do but it's about done

Kind words indeed. Thank you both

Here is a pic of one side of the power supply.

Don't tell anyone but I haven't actually bolted the cap and snubber boards down yet I'm waiting for spacers to arrive. They are insulated on the back with cork sheets though. I'll have that done this weekend I hope.

The cap bit is from the carlosfm cap and snubber diagram from the Decibel Dungeon site.

I have used knitted copper wire tube on the mains leads and the transformer is a 500va shielded unit.

Is that for shielding?. If so how well does it work.

Yes, that was the idea.

I don't know if it'll make any difference in this application TBH, I know that it's possible to shield electronic equipment from electronic surveillance by placing it in a cage made of knitted copper wire because it blocks EMR (faraday cage)

I wanted to try to reduce sources of RFI / EMI / EMR and all that stuff as much as possible and since the tube is only 1.25 per meter, I thought I would give it a go.

I don't think anyone else does this and I haven't tested it without the tube but it can't hurt I guess.

The amp is totally silent but other peoples are too and they haven't used tube.
