There are no resistors under the BIII... What do you mean?
Which version of Legato? What voltage at the supplies? You have not given many details for us to give you an answer.
An any case - both circuits were designed to be used at their indicated supply voltages. You should not have any issues if you stick to the numbers.

If you run it like that you should be just fine, but you can adjust the Legato supply voltage down to 12V rails if it makes you more comfortable.
Those kind of temperatures below the BIII should not be a problem for the BIII in any case, because it will not be getting anything close to that hot.

Mine ran hot too, as I was setting it up (balancing off-set, etc). The main problem I have is the rails draw vastly different currents, and the resistance to ground for the V+ rail is about 2K ohms, for the V-, its about 9 Mohms.
I am still trouble shooting it, but it would helpful to know what the rails resistance should be, roughly. Which of the rails on my board has a reasonable resistance?
Thanks.
