Professional service means more than just replacing bulbs. I am a professional electronics tech with over 35 yrs. of experience. I am passionate about vintage audio equipment and I enjoy going through these and restoring them to their original glory! All of my customers have been extremely satisfied with the quality of my restorations, and I’m confident that you will be as well.

Standard Services that are performed on ALL units I restore:

·ALL electrolytic capacitors get replaced including the large (costly) filter caps! Electrolytic caps age – there is no getting around that. They have already exceeded their life expectancy in these vintage receivers and other vintage audio gear. Aged capacitors negatively impact the quality of the sound. That is why I insist on replacing them ALL. I only use the highest quality capacitors (Nichicon, Panasonic, WIMA, etc.) and all are purchased through reputable well-vetted U.S. distributers such as Mouser, Digikey, etc. NO Cheap Chinese knock-offs!!

·ALL diodes and transistors which are commonly known to be problematic, are replaced with modern equivalent spec. Fairchild / Onsemi components for unsurpassed sound quality and long-term reliability. 

·       Fairchild / OnSemi semiconductors and 1% metal film resistors are utilized where component replacements are needed.

·Unit thoroughly cleaned inside and all of the internal controls professionally cleaned and properly lubricated to ensure excellent performance.

·All potentiometers and switches flushed and cleaned  with DeoxIT F5 fader and then lubricated with F100L Faderlube to insure smooth, noise-free operation.

·ALL knobs, the tuner dial window glass, faceplate, and rear audio connectors are cleaned and hand-polished.

·       The original power cord gets inspected and cleaned.

·Any missing, damaged, or rusted top cabinet or bottom plate screws get replaced.

·       All feet are inspected and replaced as needed.

·In Marantz receivers, the light-diffusing Velum paper behind the radio dial and signal strength meters gets replaced for color clarity.

·ALL solder joints checked for cold joints on all of the circuit boards under magnification and reflowed where necessary. This includes the lamp connections which are known to crack, and other high heat areas where the solder joints tend to fail over time if not maintained and serviced.. 

·The original trimmer potentiometers used for critical amplifier adjustments such as Bias and Offset / symmetry level, get replaced with new high-quality Bourns Sealed multi-turn trimmer pot’s. 

·       Amplifier DC bias/offset voltages adjusted to factory specs per the service manual for the unit. ( 4.5mVdc bias for the Sansui G-4700 )

·Power supply output adjusted to factory specifications on units that provide adjustment for it. ( not adjustable on the G-4700 )

·All functions, inputs and outputs tested and verified to be fully operational, including Phono. 

·       After restoration the receiver is put through a real life, 5-day, burn in and usage test to confirm reliability and help guarantee optimal long-term, quality performance.
