[Drake] T4X question

[telegrapher at att.net]

It seems to me that on the T-4XB there were a pair of RCA jacks on the 
back panel that may have been solder jumpered below the chassis or had 
an RCA-RCA jumper on the back of the chassis.  The object was that by 
removing this jumper you had low level drive to operate the TC-6 and 
TC-2 units.  I don't see this on the T-4X but the question is, does 
anyone know what the output power level might have been at this point? 
I need less than .1 watts of drive and wondering if  this might be close.

Thanks
