Default European SSE build

I'll let the other thread dies and replaces it with this one. It'll be my build journal.

I took the plunge yesterday and ordered the parts to populate the SSE board, waiting on George's response to order the PCB from him.

I'll go for Toroidy's OPTs as a first project, and I quite like the round shape. I'll order two of these. Are these the correct ones?

Also, there are two models, one more expensive that the other one, but it's just because it comes with a kind of polished case, am I correct? Is it easy to find third-party enclosure for the OPTs if I don't order them from Toroidy?

I cannot seem to be able to find the correct power transformer on Toroidy's website, could anyone help me out?

Should I get the choke from Toroidy's as well or opt for a cheaper one?

Is this a good choice for a coupling cap? I could also go for the Jantzen ones, but I'm a little lost here. Any advice would be welcome.

The Jantzen is a lot cheaper. 0.47uF Superior Z-Cap | RumoH - Caps, Coils and Speakers and similar in quality to the Auricap XO.

And has better a voltage rating. The XO has a 200VDC rating....(Which is ok) But the Jantzen 800VDC.

Correct.

Not hard...you could even get square ones if you like.

I think the SSE uses EL34? So you'll need: TTG-EL34SE - Tube output UL transformer [3,2kOhm] EL34 / 6L6 SE - Shop Toroidy.pl

That Toroidy choke prices look good to me. Won't get them much cheaper than that....

I could not find anything suitable either.

I intend to use KT88 on my amp, will it work even though it's not stated?

Yes it will work fine with KT88

I used the EL34 SE toroids from Toroidy in my SSE build, and I consider them to be excellent!

I also balked at the cost of the polished stainless steel potted versions. It is possible to buy metal covers for unfinished toroids, but they can be another €10 each. Sonically, I don't think there is a difference, but I think it hinges on how you want to present your work when you finish.

I also use a Toroidy PT. I just gave them the required specs, and it was a minimal charge for them to provide a custom solution. Just drop them an email. (I'll see if I can find my invoice)

(No affiliation to Toroidy - just a satisfied customer).

That's great news, thanks for the tip! It does sound like the Toroidys are very good, it'll be around 220euros for OPTs + PT. Which is very much fine by me.
