Beautiful Marantz 4400 Quadraphonic Receiver.Fully Restored & Serviced with LED light upgrades.
125wpc into 8 ohms in stereo.50wpc into 8 ohms in quadraphonic.
This receiver has phenomenal sound quality. The clarity and detail is exceptional, even at high volumes.Everything works well. When used with the Green Scope on, the effect is very unique, set off by the red, white and blue LEDs.The Phono section sounds fantastic, and the tuning section is very strong.I am ab...le to recieve a Victoria BC Station from about 100 miles away with great sound quality.
Scope works well, CRT tube is strong and free of burn-in.All lamps were replaced with LEDs, except for the tuning needle lamp.(An incandescent bulb is better for the tuning needle, it gives 360 degree coverage, while an LED would only face one direction).
Excellent cosmetics.Faceplate is extremely clean.Metal Cabinet with faux woodgrain shows some wear but still looks good overall.
Over 200 parts were replaced in the restoration process.
* Replaced virtually every electrolytic and tantalum capacitor on all boards(With the exception of the meter board)* Replaced all of the known to be problematic small signal transistors.Long term experience has shown that 7 different transistor types used in the 4400 are known for high failure rates, all of these were replaced. (60+ small TO92 resistors were preemptively replaced.)* Filter caps replaced* Various Diodes replaced* Both speaker relays replaced* Every lamp upgraded with LED (except for tuner lamp because of the qualities of incandescent, shining 360 degrees vs one direction.)* Replaced entire Dolby FM unit (multiple boards)* CRT Tube Aligned* This was fully serviced, All pots and switches were cleaned and treated with the appropriate DeOxit.* Bias/DC Reset to Factory settings.
Dimensions are 19.5" wide x 17.5" deep x 6.5" tall.Weight is 53 lbs.
Check the last two photos, I included a photo of one restored board, as well as a picture of all the parts replaced.If you need more photos of additional boards please let me know.
You will be hard pressed to find a more completely and thoroughly restored 4400.Please check my feedback and buy with confidence, all of my Stereo gear gets excellent feedback!
This will be very well packed for Safe Shipping.I have years of experience shipping large items, packing hundreds of large pieces of stereo gear, all of it arriving safely.
As with all vintage stereo equipment, No returns for any reason.Make sure you read the owners manual before using this, I am not responsible if you recieve this and ruin it through carelessness.
