I disagree with the statement that the torpedo speed cannot be set without pulling the torpedo out of the tube. Judging by the excerpt below, it appears that the speed could be changed.
Here is an excerpt from the British report on U-570 following its capture:
Quote:
The Calculating Instrument
74. The calculating instrument is in the conning tower close to the attack periscope. It is considerably more elaborate than the British Submarine Torpedo Director and has a large number of dials but it does not give a clear picture of the relative position of own and enemy ships as does the British instrument.
75. The calculator performs the following functions:
A. Calculation of Director Angle
Settings
(i) Torpedo speed. Three positions 44, 40 or 30 knots set by hand.
(ii) Enemy speed. 0 to 40 knots set by hand.
(iii) Inclination. Set by hand in the first instance and then corrected automatically for change of bearing. This gear must be switched off when resetting inclination by hand.
76. The resultant director angle is shown on a dial on the face of the instrument.

I've always understood that there are rods inserted into the torpedo while in the tube that adjust the various settings and are retracted prior to firing. I believe this report makes mention of them if you read through it.
There are all kinds of technical tid bits in the report.
Here is the link for the whole report:
