Back when I received the trannies, I drew up a simple schematic diagram of all of the leads, I'll dig around and see if I still have it.
Found it! Just where I left it 5 years ago
It is a bit faded, stained and tattered, but still fully readable.
Two 115 (120) VAC primaries:
Primary 1: Red/Black (line) and black (neutral)
Primary 2: Red/Green (line) and Yellow/Black (neutral)
For 120VAC, connect Red/Black to Red/Green (line) ; and Black to Yellow/Black (neutral)
For 240VAC: Connect Black to Red/Green; Use Red/Black for Line, and Yellow/Black for Neutral
230VAC, (850 mA) secondary: Red and Red: no-load voltage: 235VAC, fully loaded: 228VAC.
Bias: (44VAC) Blue and Blue - note: Low current
6.3VAC, 5A Filament #1: Green and Green, CT Yellow / Green
6.3VAC, 2A Filament #2: Yellow and Yellow.
6.3VAC, 2A Filament #3: Orange and Orange
These two windings can be connected in parallel for 6.3VAC @ 4A, or in series for 12.6VAC, 2A. There are no "phasing" markings,
so there is a 50/50 chance of getting either the "right" connection
, or the "wrong" connection
.
I tested it with the 230VAC and 6.3VAC windings fully loaded: 228 VAC @850 mA on the 230VAC winding, loaded to 850 mA (2 100 watt, 120V light
bulbs connected in series). Line voltage was 120VAC.
For full wave bridge, divide 850 mA by 1.8; For a voltage doubler, Divide 850 by 3.6. This is the "conservative" DC current rating method.
For a full wave bridge, max DC loading would be 472 mA continuous. For a voltage doubler, the max DC loading would be 236 mA, continuous..
6.3VAC, 5A winding loaded with four 6AV5GA filaments (1.2 A each) connected in parallel, for 4.8 Amps loading.
No loading on the two 6.3VAC 2A windings
I let it run for many hours, the transformer got warm, but not hot to the touch.
This thing is a BEAST!
