Just got a Rohde & Schwarz EK47 receiver today.  Unfortunately, it did not 
come 
with a manual, so i do not know how to wire it for 115 VAC operation.  Can 
anyone on the list advise on how to do this?  Better yet, anyone know where 
to 
obtain a copy of a manual?

Thanks,

Hi Paul, congratulations on your EK-47. Normally these are wired for 220V 
operation in Germany and probably other countries in Europe. You will need to 
remove the top cover and locate the power transformer on the left hand side near 
the rear of the chassis. There are 3 terminal strips around the transformer to 
the left side, right side and front side. The terminal strip facing the front 
side has the taps for line voltage. You will need to strap contacts a5-a7 for 
125V operation. If it is now strapped for 220V operation there will be a 
strap across a4-a7. Just change one side of the strap from terminal a4 to terminal 
a5 so the strap will be across terminals a5-a7 and you will be set to go for 
125V. Also for 125V operation the fuses in the back should be for 2 amp 
rating. If it is currently set up for 220V the fuses will be 1 amp. 73 Todd Roberts
