Ready to just plug and play! Professional service means more than just replacing bulbs and capacitors. All service is expertly performed by myself- I’m a professional electronics tech with over 35 yrs. of experience. I’m very thorough, extremely meticulous in my work, and I never sell anything that I wouldn’t be proud to have in my own personal hi-fi collection! Below is a list of the work that is performed on ALL units we service / recondition: · Unit thoroughly cleaned inside and out. · All potentiometers and switches flushed and cleaned with DeoxIT F5 and then lubricated with F100L Faderlube to insure smooth, noise-free operation. · All Dial, tuning meter, function and dial pointer lamps replaced and upgraded to LED’s for the ultimate in reliability. · ALL knobs cleaned with ultrasonic cleaner, then hand-polished. · The tuner dial window glass, faceplate, and rear audio connectors are cleaned and hand-polished. · ALL electrolytic capacitors get replaced including the large (costly) filter caps! Over time electrolytic caps age and will trim your low and high frequencies, as well as make the sound dull, rob power and more. They can also fail completely and/or leak electrolyte, damaging other components and circuit boards. They can also go up in smoke or explode! That is why I insist on replacing ALL ELECTROLYTIC Capacitors, INCLUDING THE COSTLY MAIN FILTER CAPS. I only use the highest quality capacitors (Nichicon, Kemet, Rubycon, Panasonic, WIMA, etc.) and all are purchased through reputable well-vetted U.S. distributers such as Mouser, Digikey, etc. · The original power cord gets inspected and cleaned. · Any missing top cabinet or bottom plate screws get replaced. Any other screws on or inside the unit which are damaged or rusted also get replaced, unless they are a type not readily available. · All feet are inspected and replaced as needed. · In Marantz receivers, the light-diffusing Velum paper behind the radio dial gets replaced for color clarity. · ALL diodes and transistors which are commonly known to be problematic, (there are some that are known in the tech community to not age very well and fail or become noisy, distorting the sound) get replaced with modern equivalent spec. Fairchild / Onsemi components for unsurpassed sound quality and long-term reliability. · 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 failure-prone bias trimmer potentiometers are replaced with new high-quality Bourns Sealed multi-turn trimmer pot’s. · Speaker protection relay replaced with new, top-quality Omron replacement. · Power supply output adjusted to factory specifications on units that provide adjustment for it. (35Vdc for the 2230b) · Amplifier DC bias/offset voltages adjusted to factory specs per the service manual for the unit. (20mVdc for the model 2230b) · 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. · Marantz 2230b Stereo Receiver Specifications: · Tuning range: FM, MW · Power output: 30 watts per channel into 8Ω (stereo) · Frequency response: 20Hz to 20kHz · Total harmonic distortion: 0.3% · Damping factor: 45 · Input sensitivity: 1.8mV (MM), 180mV (line) · Speaker load impedance: 4Ω to 8Ω · Dimensions: 440 x 137 x 356mm · Weight: 12.2kg (26.9 lb.) Due to the age of this device, this equipment is being sold AS-IS with NO RETURNS or adjustments. This is NOT a new component. As such, it does not come with any guarantee – implied or written. I would love to be able to provide a warranty on these units, as I am fully confident in the work / testing I have performed. However, there are unprincipled individuals out there who will buy equipment, rob valuable parts, and then try and return the product for refund. I am forced to protect myself from such fraudulent actions by selling the item AS-IS with NO Returns allowed. I've shipped many vintage audio items, and I will pack VERY securely to ensure safe shipping. Note to any scammers -> all boards and valuable parts have been discretely marked and photographed, so please don't even try.
