Connection bolt of the amplifier with an installed steel strip

Connection of the steel strips with the threaded rod

The RLA4 versions D and E possess individual elements made of printed circuit board material (FR4) 
instead of the stainless steel loops. Each closed loop consists of 2 elements, each of which must be 
screwed on using short M4 screws (Torx) and a spring washer. For this purpose, the connecting bolts of 
the amplifier have vertical flat surfaces with threaded holes. At the top of the threaded rod 2 mounting 
cubes with 4 internal threads each are installed. In total, 3 screws with spring washers are required for 
each loop section (one for the connecting bolt, two for the mounting cube of the threaded rod).

The following images illustrate the assembly of the loop elements.
