I, like Sam Goldwasser, am repairing a centrifuge
and have a problem with,

LAS1412: All I could find on this part is that it is a voltage regulator
from Lambda.

JTB2405 I think is a Diode bridge but I can't find anything on it.
but after reading Sams post a Solid state relay seems more likely.

Now the question does anyone have a datasheet or even a schematic for
the machine or worse case a schematic out of another machine with the
same parts so I can work what the ratings of the devices are? Hell any
clue would be a good clue at this stage. :)

This crosses to an NTE1912 which is a 12V regulator in a TO-3 package.

Vin(min/max) = 14.5V / 30V
Iout = 3A
Pd = 30W

Pins 1,2, and case correspond to Vin, Vout, and ground, respectively.

Any other markings, logos? Whatever it is, an obvious guess would be
that it is rated at 240V, 5A.
