Mine has the 2.5W diode, or at least I paid extra to get that diode and I trust that it is indeed that diode.
BUT let us pretend for a minute that it is only the 1.5W diode. It still only needed 1.1W to produce 375mW. If this is the case, regardless of what the current may or may not be, we KNOW that the diode was only putting out 1.1W. So it really doesn't matter which diode it is, or what current it is drawing, because the output power is still lower than BOTH of the different diodes used.
Today I am going to take the crystal set off again and will measure the raw pump diode output. I'm measuring 2.2A of current draw. I'm going to suspect that the pump diode is putting out between 2.2 and 2.4W.
The voltage across the diode and before the diode but after the driver is only ~1.8v. The overall voltage available is probably around 8v although I'm guessing it is a bit less because these batteries weren't full by any means.
