I normally use VE for phono manuals -but their copy of the BP-1.5 manual doesn't include the diagrams. My BP-1.5 was made in 2000 ? Rev. 3 ? so it's the full size model. So-here's the question : The two positions of the gain jumpers are XX gain with jumpers to front and XX gain towards rear panel ? Probably just need a diagram from the manual.
