[ARC5] weight of a typical SCR-274n / ARC-5 R-25 or -27 w/dynamo (not rack mounted)

[Henry Mei'l's]

Hi - Can't seem to find weight specs and I don't have a downloaded manual. 
What is the weight of an R25, R26 or R27 incl. dynamo and not mounted on a rack ?
(Where can I download the TM for ARC-5 / SCR-274N ?)
Thanks in advance,
 Henry
