With their high build quality and impressive performance, Pioneer is recognized as one of the premium makers of high-end equipment for the audiophile since the late '30's! Released in 1972, with attention to outstanding performance and versatility, the SX-424 is perfect for those who prefer quality over volume. It retailed for $200, that's just over $1,600 today!With its extraordinary engineering, advanced design concept and extreme flexibility, Pioneer's SX-424 AM-FM stereo receiver offers a level of performance that can only be described as awesome. Its exceptional FM reception is achieved through the use of a low-noise FET RF amplifier and FM Muting circuit. So it cleanly and clearly picks up stations that were once just numbers on the dial - without interference. There's also a front-panel Mic input and the ability to use the Tape Loop as expansion jacks for 4-channel applications!The front panel offers a multi-position Speaker Output selector, concentric R & L Volume controls, click-stop Bass & Treble controls, and buttons for Stereo/Mono, FM muting and a Loudness button that contours the sound dynamics perfectly for low level listening.While the manual gives this a "Music Power" rating of 50 watts @ 4Ω, we prefer to use the more reasonable "Continuous Power" rating of 24 Watts, 12 W/Ch into 8Ω, or 26 Watts, 13 W/Ch into 4Ωwith both channels fully driven. Remember, these are what audiophiles call "Vintage Watts," from an era where, unlike today, it was a sin to manipulate or elaborate the power ratings!The front panel has both 1/4" Headphone & Mic jacks while the rear offers two speaker zones, an Aux Input, a Tape Loop with the PLAY/REC DIN jack found in the higher-end offerings of the era that's also ready for 4-Channel applications, and a stereo Phono Input with a grounding post for your turntable! It also has multiple antenna terminals, an attached AM antenna, two AC outlets, switched & unswitched, a power fuse-holder and user-access to the protection fuses. It weighs in at just under 17 lbs and measures 13-3/4" x 5-3/4" x 17" wide!

NOTE: This receiver uses Pioneers speaker connectors for connecting your speakers to the custom speaker jacks. We are including the pictured pair for using the main speaker outputs, you will need an additional set to use the second speaker outputs. They are available from multiple sellers.

By "The Best, Ltd." policy this unit will be double-boxed for secure shipment.The Free Shipping is for the Lower 48 only, HI & AK must select USPS Priority shipping at checkout!Insurance & Signature are covered on us!Paid itemscan be picked up in the Denver Metro area at no charge.

Condition:This beautiful receiver is in"Very Good" condition with minor signs of use and a nice, clean front panel! Aside from a few scuffs and a touched-up spot to the veneer, the only other thing worth mentioning is just a few light front panel scuffs, most too faint to see well in the pics. All original knobs are present & complete,as are the feet and attached AM antenna &AC cord.The manual had gone missing, so we are including the pictured copy.A bonusNEWFM Dipole Antenna is also included. All comes in the pictured generic box with custom Styrofoam packing.Please do inspect all the pictures thoroughly for actual condition.Service:On inspection, this unit was working but had scratchy or inconsistent controls and a dim dial, so as with all vintage receivers it went to our tech for servicing.First, Pioneer used certain transistors throughout this model that have known issues after 40 years. So, whether or not they were still working, our tech insists on replacing these transistors as they will assuredly fail some time in the near future.While our tech does not believe in doing a "shotgun" style "re-cap" on most gear made from the late '70's on, he does make sure there are no capacitors with detectable or known issues.This receiver had several of the blue Sanyo caps that are known to fail along with several that showed signs of overheating or degradation, so they were all upgraded!A total of 17 transistorsand 12 electrolytic capacitors were upgraded to brand new. high quality parts from Onsemi, Nichicon, Rubycon, etc., no used or NOS components!It's this kind of thoughtful, preventative servicing that makes it smart to buy from a company with an experienced, in-house technician!Only one lamp was still working, but as it was most likely going to fail soon all the lamps were replaced with long-life LED's!We installed the new frosted CoolWhite LED's in the dial which shinethroughthe blue dial with betterconsistently, then a Green LED was chosen for the meter that contrast the dial beautifully.But if you prefer a Warm White LED that shines through the meter with the original bluecolor, just let us know BEFORE buying or sending an offer and we will switch it out for you free of charge!Even the Stereo indicatorand the hard to replace pointer lampwere upgradedso you won't have to worry about them ever again.In fact, we weren't happy with the lack of illumination the unidirectional LED's give on these pointers, others just resort to using an incandescent. But as longevity is the whole idea behind the LED upgrade, our tech has come up with a custom way to install a 1-segment LED that illuminates the pointer much better.All vintage receivers receive the following services and much more, all performed by our qualified technician:

• Lid is removed & unit is inspected to determine if any attempted amateur repairs exist that need to be corrected, or substandard parts that need replacement
• The exterior, all knobs & plexis are cleaned & detailed
• While the front panel is removed for cleaning, all attachments are re-glued and dried out foam inserts replaced.
• All switches & pots are cleaned internally with Specialist Contact Cleaner (proven superior to DeoxIT by our customers), while those with special needs receive the less aggressive DeoxIT F-5
• All lamps that are out, or believed to be prone to failure, are replaced if necessary. LEDs are used whenever compatible
• Any faulty components, or those with known issues, such as jacks, fuse-holders, feet, etc., are replaced
• All PC boards are inspected; all questionable solder joints are re-flowed
• All electrolytic caps are inspected for bulging or leakage, those that are at risk or have known issues are checked with the Huntron Tracker (allows evaluation while in-circuit so component does not need to be removed). All questionable caps are replaced with brand new parts, not NOS!
• DC offset is adjusted & channel levels are calibrated & balanced
• Tuner is cleaned and both AM & FM aligned
• Front panel is cleaned & detailed before reassembly
• Cabinet is cleaned & detailed, any wood is polished with Old English

Testing:After servicing, we set it up on our test bench and it did not disappoint, both channels drove our speakers with the warm, distortion-free audio these analog receivers are known for. All inputs and features were confirmed operational and the tuner spins smoothly. We are in a remote area so we did need to use the included antenna to pull in all our local FM stations with the included wire antenna, activating the tuning meter and lighting the Stereo lamp. Further testing was performed, if there is a specific feature you would like to know more about just let us know before buying. What a great find for the vintage audiophile!
