SE 6C33C-B ; preview of a new Baby

[Alain Dupont]

Hi,

Ouf! after about 8 month of hard work, I give you the preview
of my SE 6C33C-B

Just only a few holes to drill !!!

Regards.

Alain.

 

[Giaime]

It looks suspicious without the power transformer!!!

Anyway, great work! I love those wood chassis. How did you make that front hole?

 

[Alain Dupont]

Giaime,

An other chassis will have 2 separated PS's one for each channel...

Regards.

Alain.

Giaime,

All done with a table saw and a router... But it's a lot of work...

[Alain Dupont]

Regards.

[Alain Dupont]

Final,

For now.

Alain.

 

[Ryssen]

Looking nice!Nice harware work!

 

[djQUAN]

how did you do the finish (and the lettering...) on the aluminum plate?

 

[Alain Dupont]

Ryssen.

Thanks.

djQUAN,

The finish is fine sand paper, and Polyurethane varnish 2 coats...

For the lettering I use decals from Antique Electronics Supply,
I don't know if they still sell these products. Once the letters applied
with pressure of a pen, then the plate gets 2 coats of Polyurethane
to seal and protect. {gives a nice look!}

[djQUAN]

looks good. and probably will look better finished.

 

[Alain Dupont]

djQUAN,

I expect it sounds good too !!!

There is also the same chassis for the separated power supplys.. a lot
of aluminium work ahead!!

The original design is from Ari Polisois:
