Add COOL VU METERS To Your Marantz Receiver
Very Nice Condition Inside and Out! This rare Marantz amplifier has been Professionally Serviced by Crossed Paths Vintage and is in very nice working condition. This is a wonderful unit that incorporates the classic Marantz warm sound with exceptional details and wide depth that is very impressive. Full working condition and... an excellent choice for any stereo or quad setup. This unit has been thoroughly tested in all modes and works wonderfully. No additional expansion cards are included. Be sure to scroll to the bottom of this listing for 12 additional detailed pictures that show just how nice the unit is!
This unit has been thoroughly cleaned inside and out as well as the internal controls have been professionally cleaned and properly lubricated to ensure excellent performance. All pots have been professionally cleaned and lubricated as well. All capacitors, transistors and resistors have been verified to be in spec and were replaced as needed. We use a stricter 5% tolerance when checking all parts to ensure a long future for your "new" vintage purchase. Most specifications allow for a +- 20% discrepancy and we use +- 5%. All solder joints have been checked for cold joints under magnification and reflowed where necessary including the high heat areas that notoriously fail if not maintained and serviced. We use Nichicon High Temp Electrolytic Capacitors (UPW, UKL, etc), Nichicon Muse Capacitors, Elna Silmic II Capacitors, Panasonic Electrolytic and Film Capacitors, WIMA Stacked Film Capacitors as well as Zetex, OnSemi and Fairchild semiconductors and Xicon 1% metal film resistors when needed. Bourns Multi-Turn and Sealed Variable Resistors (Potentiometers) are used for critical amp adjustment points. Omron Audio Grade Relays are used in the protection circuits. Most consider these the best choices for vintage restorations and we always upgrade the voltage and temperature minimums on capacitors when appropriate to provide even longer service than the originals. This unit is ready to go! This one owner unit came in working well, but we thoroughly go through the unit to ensure its longevity.
All knobs, switches, faceplate, bottom cover, top cover, internal chassis and input connections were detailed, deep polished and ultrasonically cleaned where appropriate. This cleaning process alone takes 4 to 5 hours with the complete dismantling of the unit.
The lamps were serviced while the unit was restored. All service manual calibrations have been performed throughout the unit and they are spot on.
All inputs work as they should. This amplifier can be used in multiple ways and is feature packed. It's the perfect accessory for a Marantz 2270, 2245 or 2230 or other 70's Marantz receiver to add VU meters for the outputs and give you additional amplification that can be used in multiple ways. It has 2 tape loops that give added flexibility...awesome sound and performance!
This unit comes ready to enjoy in nice cosmetic condition with minimal wear and tear for a unit this age as shown in the pictures. This unit was not abused by the original owner and comes from a non-smoking home. The pictures show just how nice the unit is and you can zoom in on each picture to see additional details. Feel free to ask us any questions you might have. Fast shipping with 1 day turnaround.
