RV HIFI says:

Superb Yamaha EQ-630 Stereo Graphic Equalizer, completely restored and sounding amazing! A lot of time went into making sure that this piece came out perfect and it did, high-end electrolytic capacitors were used, all the PCB’s got a full inspection and suspect joins re-soldered. The spectrum display globes replaced and a new back-up battery installed. The top cover case was not 100% so we sandblasted and re-painted the surface. Better than new and sound quality amazing because of the quality of the caps.


RV HIFI is passionate about Vintage HIFI, so we believe in doing the job right!
