It looks unlekely, that we will have 10+ pcs level for this GB.
Is anybody interested except me in transformers on 5+pcs pricing level ($302 + shipping)?

8 transformers short
If someone else would like couple of transformers, I may try to ask 5pcs price level for 4 of them.
$400 per transformer doesn't look reasonable for me

Default New (lower) prices for fewer windinhs

I decided to try one more time with toroid.com, having only essential windigs this time:
Code:
Primaries: 
dual 120V 
 
  
Secondaries (total 5 windings) 
bifilar 2x 38V RMS at 12A RMS (39.5V 0a) 
bifilar 2x 60v RMS at 0.8a 
single 18v x 0.8a 
  
STATIC SHIELD between primaries and secondaries. 
MAGNETIC SHIELD = 70mm
Prices:

2-4 pcs: $362.52
5-9 pcs: $250.93
10 and more: $209.93

So there may be a chance of them at $250.93

Let's start with $250 price level, which is lower then 10+ from previous quote and close to prices from off the shelf transformers without shields/screens and non-bifilar secondaries

Good, looks like $210 price level is possible
Please ask bobgroger about the boards in the main thread. Worst case scenario you can take gerbers from him and submit them to your favorite PCB manufacturer.
