JLM VU Buffer kit allows for a easy neat way to turn cheap dc type VU meters into working VU meters. It is also extremely useful for buffering a real VU meter as it isolates the Total Harmonic Distortion caused by the internal rectifiers in the VU meter. This will usually drop the output THD of most circuits running VU meter direct another decimal point which is a good improvement.VU Buffer can run on any DC voltage from 9v to 30v.
VU buffer PCB measures 1.45" (36.8mm) x 1.5" (38mm)
