Semi-customized. The shape of front plate, depth, height, and heatsink was fixed. Others were customized.

I assume these cases are from China? Any hint as to who/where they are from?

Everytime I see one of your pics, I keep thinking I like those... :)

Not built, still waiting for the custom transformer, and a bigger issue is the lack of a drill press and the related skills.

Still being a very young padawan in DIY. Need some more weeks before completion.

Yes, I´m waiting for two trafos too.

TS300VA PRI: 230V

> 2x360V @350mA

> 18-0-18V @600mA

And:

TS50VA PRI: 230V SEC:

> 6,3V @8A

 

I don´t think that you have problems again if you use the "top" board (tube side) for put the conector.

Received the transformer today.

Didn't imagine such a big boy. But perfectly built.

Changing plans for casing, unless it won't fit.

Despite some mistakes and need of adjustment (make the tubes symmetrical for sure), you get the idea :

Nice work G600 I can not see the tag of your trafo but I have one question: EL34 uses 6.3vol @ 1.5A, if you use four EL34= 6.3vol @ 6A.

Your trafo only have 4.5A current so I understand that your transformer goes very low in amperage.

 

Edit: Sorry, it´s 2x 6.3volt @ 4.5A
