Description
Shipping to USA addresses only. Contact me if you have a secondary address in the USA (this way I can ensure your bid wont be automatically blocked). I do NOT use stock photos or canned descriptions. The vast majority of buyers want to see an items actual condition, not glossy photos from the manufacturers site. You can find the manufacturers description and specifications via online searches. Pictures may include test equipment, cables, connectors, and auxiliary equipment that are NOT a part of the auction. Read the description carefully so you know exactly what you are bidding on. This listing is for a very clean Sony TA-4650 integrated amplifier. I put Power Amplifier and Preamp in the title because the pre- and power amp sections can be used independently via jumpers on the rear panel (see photos--original jumper blocks included). Everything seems to be working normally except the SPEAKER selector switch when in the A+B position. Speakers connected to terminals A work fine, and same for speakers connected to terminals B. The relay on the PCB appears to be a mute-only switch (provides delay during warm-up to check for DC or to avoid thumps). I dont see any fuses that are linked to the A+B position (over-current protection when 4-ohm speakers connected in parallel). The very top of the PCB flexes slightly due to the weight and tension of a Sony factory wire bundle, so theres a chance the A+B mode is affected by a marginal PCB trace. Again, the amplifier sounds fantastic when using speakers connected to either A or B. All of the input functions work well. For the most part, I used this TA-4650 as a power amp only. Compared to conventional BJTs (bipolar junction transistors), MOSFETs, and even vacuum tubes, I prefer the sound coming from V-FETs better than any tubed or solid-state component. The amplifer is super-quiet (no hum or hiss), and bass is very tight (hard to achieve with many tubed amps). I wouldnt be selling this Sony TA-4650 except that I finally completed building a stand-alone V-FET power amplifier using the same Sony transistor type found in this unit (complementary pairs consisting of a 2SK60 and 2SJ18). The unit being listed here is all original Sony (no repairs, no replacement parts). I normally avoid 10-day auctions, but I wanted to be home a few days ahead of the auctions end day so I can pack and ship the units in a timely manner. Be aware this auction ends on a Friday evening. You can see that the Sony TA-4650 weighs in at 27 lbs (unpacked). This item will be carefully packed and shipped via FedEx Home or Ground. Reminder: I do not ship to addresses outside of the USA. Thank you for viewing! Im batting 100% positive feedback after nearly two decades of buying and selling on eBay. I kindly leave positive feedback for those who do the same. Some recent feedback (as a seller) includes: Possibly the best seller on eBay Ive dealt with. Highly recommended. / An extremely helpful seller! Thank you for everything. / Great seller! An expert in sound measurement. Very responsive to questions. Prior to my current username, I had over 2000 combined selling and buying reviews with 100% positive feedback (Ive changed my username once or twice over the many years). I do not entertain best offers, nor do I end auctions early. Item will be sold to the high bidder (heck, a single bidder might get a fantastic deal). My auctions are old-fashioned auctions--the way they ought to be. Payments must be received within 72 hours after end of auction. Items not paid for after 72 hours will be re-listed. No returns (buyers remorse shouldnt be the sellers responsibility--see * below). Nothing in this listing is misleading. Photos are an integral part of the description: View all photos carefully. If something isnt clear, write before you bid. I pack items with great care--the same way Id like to receive a delicate or valuable item. Like other sellers, I do not have control over shipping costs or carrier delivery time. Small- and medium-sized items will be shipped via USPS Priority Mail. Large parcels will be shipped via UPS Ground. Unlike Jeff B, neither eBay nor I operate our own shipping services--this means no prime or overnight shipping. *Heres why I no longer accept returns: Too many bidders with buyers remorse had intentionally damaged perfectly good equipment in order to receive a return. In other instances, buyers were simply incompetent: Equipment was damaged because these buyers did not know how to properly use it; yet, they wanted refunds because of the damage they caused. Bottom line: NO MORE RETURNS! If the wrong item is shipped (I have yet to do this), I will promptly exchange the item and pay for shipping to-and-from the buyer. Please understand what youre buying is USED (unless its clearly stated as new). RE electronics equipment: I encourage all viewers to compare my listings to other sellers listings and photos: If a printed circuit board is on anything other than an ESD mat, then the seller doesnt know how to exercise appropriate ESD precautions. Many electronic devices are easily compromised or destroyed due to improper handling. I use appropriate ESD protection measures when handling static-sensitive equipment. Items that are ESD sensitive will be shipped in anti-static wrapping.

Description
Introducing the Sony TA 4650 VFET, an exceptional audiophile integrated stereo amplifier that delivers an unparalleled sound quality. This rare and fully serviced piece of audio equipment boasts 2 channels and a variety of audio inputs including AUX, Phono/Turntable, and Stereo L/R RCA. The brand, Sony, is synonymous with quality and this model, in particular, is highly sought after by music enthusiasts. This is TRULY RARE! FULLY SERVICED !! NOT BASIC SERVICED WITH JUST SWITCHES AND CONTROLS CLEANED UNIT. Here is what has been done to give you and idea! How this is different from all others : The full service took nearly two month to complete!. 1. Power supply completely rebuild with NEW better than orginal electrolytic capacitors including the two large main 4700uf/50v capacitors , all capacitors are quality nichicon FG , UKA, UKT made specially for audio use . The coupling capacitors are German WIMA film capacitors . These capacitors are used in only the finest audio components . Every single diode and transistor and resistors replaced with quality new ones again better then the tired old ones . The power supply had the double diode mod in place of D413 the center of this diode tied to the common ground power supply for rock steady +- 55 source voltage for the VFETs. Bourn and vishay precision multi turn 2.2k potentiometers installed in power supply board and F power amp driver board . All transistors on power amp board are new. The 2SA705 transistors replaced with BC556B transistors in differential amp and closely matched in hfe gain for ultra low DC OFFSET. 2. There are 3 infamous double diodes in The F power amp These are also called death diodes as they are know to take out the precious VFETs when they go out of order without any reason , these death diodes have be replaced with twin 1N5148 diodes for each of these diodes. THIS IS A MUST DO IN ANY SERVICE OF ANY SONY VFET AMP! PERIOD! Just cleaning the switches and controls is not enough! All electrolytic and almost all coupling capacitors are new on this board , the power supply and the various pre amp board . The 4X 0.47ohm/5w power resistors on power amp board are new quality vishay ones. 3. J113 N channel JFET transistors installed in place of 2SK24A in pre amp for superior sound , the phono section has2 original Sony minature 2SK63 VFETs for truly awesome phono sound from your quality turntable . 4. New Teflon wires installed were necessary. 4X new 470 ohms resistors in headphone board . The speaker relay points cleaned and polished . All controls and switches cleaned for maximum performance . 5. The four VFETs are original vintage SONY all tested . Before VFETs were installed the DC bias adjust pots were adjusted to show maximum voltage reading in this case +- +- 79 to +- 80Vdc on each gate of eachVFET. 6. So much work was done that it would take a book to list all , the above is just a digest of things done. NOTHING WAS LEFT TO CHANCE! To bring you a truly exceptional SONY TA 4650 RARE VFET Amp. As you might already be knowing VFET transistors were developed by Sony to sound like a vacuum tube sound without the heat of a vacuum tube . THEY ARE RARE AND HIGHLY SOUGHT AFTER AS THEY HAVE WARM MAGICAL MIDRANGE SOUND WERE MOST OF THE MUSIC IS . This fully serviced unit sound SIMPLY SOUND AWESOME ! I have a video in the listing with sound of bob Jane’s fantastic live jazz music track called” TOPSIDE” PLAYING from my apple ipad the headphone socket of the iPad connected with a custom made monster cable with mini stereo headphone connector on one end and the other end having left /right RCA standard phono male connectors which then connected to AUX 1 of the amp. The phono section was also tested with a quality vintage Sony PS 1800 A Historic vintage professional belt drive turntable with pitch control . The sound again truly superb with great stereo separation and details in music. There is some cosmetic wear which to be expected after 40 years since new in form of scratches in chrome of the front panel and a bend in the gray metal top cover rear left bottom corner and some cosmetic wear in gray finish and in the bottom side which was touched with matching gray paint . None of these distract from it good looks as can be seen in the video any many high resolution pics. The power Indicator bulb is blue led which is much better looking and long lasting then the regular bulbs Whether you are a novice or an experienced audiophile, the Sony TA 4650 VFET is a must-have addition to your home audio system.
