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.
