marvelous, day!
Where do you get those opt?

I believe the Atma-Sphere amps are OTL.

That PSU for the 807 amp looks sexy!

Man,

i just feel myself sitting there.

Still the taste of coco, lemon grass and nam plah on my lips.
Just relaxing, my tummy pleased, on a nice comfy chair.
Enjoying the glow of them tubes and the smooth finish of the wood, listening to the sound the combo's produce.
Who knows, heaven may be in Thailand.

Nice work, Jay Day.

Very nice.

Why did you place the power transformers like this(first picture)?
Now the channels are not identical!
What kind of OPTs are these?

 

[Coulomb]

Hey Gianis, what's with the cheap cables?

Your next DIY project perhaps?

BTW, very nice work on the amps, must sound a little bright in a room with a ceramic floor.

OK - the first diy project is in, maybe I should have stayed awake in metalwork class but it sure sounds great.

Are you sure you used large enough screws to hold the chassis together?

Looks good for a first effort.

I used a piece of zinc (yeah - I know) for the chassis & it was too flexible once I mounted the xformers. Being the bodger that I am, I bolted 2 struts of steel underneath! Actually the mounting bolts gave me somewhere to add a PC board ground bus bar which has been pretty effective since this baby is oh-so quiet.
