Interior, very well built and very good pcb's ^


 

Special futures:


Light and small footprint amp. Wood case. Well build and good parts used.
This amp employs all silicon transistors and 2x STK power packs STK0040 type II.
There is also a version with 4 power transistors, but there is no "Bridge function switch" in that version.

This amp is a fine and compact power pack, that is reliable and easy to transport, works on almost any pre-amp.
I have tested it on a Quad 33, a Luxman C120A, a Sansui, and several others: always works fine.
