Looks good, Ian. I like those cases for external PSUs.

It is a standard one from modushop in Italy:

Did you send the panel to Schaeffer, or did they just make a new one to specs?

They made one from scratch. Modushop provide dxf files of their cases so it is easy to draw up a panel.

I now have the three main components; front panel, main board and rear panel, set up on the bench ready to start wiring it all together.

For some time I have not been enamoured of the off the shelf enclosure I chose for this project. It is a nice shape and is reasonably priced but..... the large main board on the floor is wired to the rear panel and also to the front panel. The more I get through wiring these three together the greater the maze of wires. I really am not looking forward to trying the wiggle these three big components into the enclosure whilst ensuring none of the cables gets too close to a tube. And I really don't fancy taking it apart again if something goes wrong.

The 'Neat Enclosure' thread I started back in mid February suggests I was not really happy with the current enclosure more than two months ago. Fortunately, KidS|quid in that thread has come up with some good ideas which make the whole thing look a lot more like a small mixer and could simplify assembly considerably. So as of now I am putting the whole project on hold whilst I resolve this issue.

I will keep you all posted.

Cheers

Amazing!

To whet your appetite, here is a pic of a lash up I put together the other weekend just to get a feel for what it will look like:

Beautiful Ian, I hope I one day can build a small tube mixer for my studio.

Quick question (might be answered somewhere else, sorry if so): what ht voltage does the TLA expect? I am playing with the idea of adding one of these boards on the input side of the DAOC I'm building to use it for input gain (so I can use trimmers in place of the pot meters in the compressor circuit to accurately match gain between channels) and was wondering if I could use the transformer I'm using (250ac secondaries + 9v for the heaters)


Se orry if I'm off topic, and looking forward to the continuation of the thread!

The TLA will work on any HT voltage from 250V to over 300V. It requires 12V heaters, preferably DC.
