Grundig tuner preamplifier for driving active speakers or separate power amplifiers. It's the Preceiver X55 in a graphite-metallic color. The unit has been in use for many years and appears to still be working, except for one minor defect. The control for fine-tuning the individual stations no longer moves; only a hissing noise can be heard on FM and AM because the channels cannot be selected. Everything else works (buttons work, as do the LEDs and levels). The visual condition is good with age-related wear. The case is intact.
