Re: GC Power transformer, looks like this?


No, the Gaincard transformer is much more massive and substantial. The shape of the core is similar, but the Gaincard core seems to be made out of a flat ribbon of metal wound up to make the donut shape. The cross-section is, therefore, square and not round. Also the GC core is much wider. If you took one of the pictured cores and laid it on its side, then laid another one on top of it, that would be more like the relative dimensions of the GC core.

Because the core is wider, the coils on the GC form a big, blockish mass. The windings are covered in craft paper. The transformers in the photos look flat. In the GC, the coils forms more of a block (equal in dimensions around the core, just a little longer along the length of the core).

Also, the GC transformer has it's mounting plate at the short, round end of the core. This is then bolted to the front plate of the Power Humpty. In effect, the transformer is being suspended in air along the length of the Humpty by the front plate. The wires then come from the other end of the transformer and attach to the connectors on the back plate of the Humpty.

The GC transformer is much more hefty looking. If you hold the 4700 "s" Power Humpty, you'll see that it's quite heavy. Just about all of that weight is the transformer. It's quite impressive.

Hope this helps,
