Those what you see are power supply chokes the power transformer is a R-Core mounted flat under the chassis.
The amp is a OTL no output transformers.

Oh, it is a OTL, my bad.
 
The pair Tango cost $431.09

Griffin,
 
I don't stock these, but can get them on a special order basis.  They are $150 each, plus shipping.  The transformer covers are $24 each.
 
What power transformer you need is dependent on your circuit.

It is my understanding that good output transformers are costly. unfortunately

The most critical part IMHO.

I would go with the Lundahl transformers studio equipment uses Lundahl.
The next amp I build is going to be transformer output and use Lundahl Transformers.
And $150 each is not that bad for high quality Transformers.

Shoot, I already sent money for Tango fe25-5

Because I did not hear from Lundahl for a few days when I email them for qoute. I hope Tango FE25-5 are the right choice. I did not go for Hashimoto and Tamura because their tonal signatures are on the clean airy and lean side the house. Not my tast.

Both Tango and Lundahl have good reputations.  I think it will work out okay for you. 
 
To echo SO, I'm curious too..... are you doing your own DIY project?  If so then you're far more courageous (not to mention skilled) than I am.

Mr. Glenn is going to build this for me as prototype, I shall ask him offer this to public

 
So far I got:
 
 
The soul Tango FE25-5
 

 
 
 
Custom case will be refinished by PanelExpress for cut-outs
 

 
 
 
 
LEGENBURG Rectangular HOOK-UP Wire RED, 20 awg (UP-OCC Copper Mono-Crystal design) and some Neotech 12 awg  Solid-core UP-OCC COPPER Wire, Teflon

 
 
 
 
 
NKK S823 20+ amp@125v rating. Silver plated brass for all contacts and terminals

 
 
 
 
 
SCHURTER - CD64.1101.151 Swiss made swich 10 Amp
 
 

 
CMC 878M-SE, with set screws, I tried to avoid solder connection when I could for signal path. I looked at Furutech, WBT, Vampire, and many others. They either toooo expensive, not glod plated copper or, no set screws.

Man, are you thick! 12 gauge solid core wire? That is thicker than my house wiring!

The 12 awg is only for short speaker signal pass through section (in and out). Most good copper speaker wires are between 12 to 8 awg. I don't want this "amp" to be the bottle neck in my speaker signal path. I took apart my little table top Dear MP-5 tube amp which got 14awg wire to speaker posts. So I think 12awg to be minimum.

Looks like someone went holiday shopping...nice effort, Seamaster! I need to throw down a project (DIY) in 2013...

I remember my college days were everyone laugh at me using 14 gauge wire for the speakers where everyone else were using 20 or 22 gauge for speakers wires.
