Stereo Line Preamplifier
The Boulder 810 is a dual mono line-level stereo preamplifier which goes to great lengths to ensure noise is kept to a minimum. It uses two separate torroidal transformers - one for audio and one for it's logic control. It also uses two separate circuits boards; one for each channel. Its build quality is impeccable - even the feet and buttons are well engineered.
This particular one is in great condition and it includes the original remote.
