For Sale one vintage (1975-1977?) Sony TA-4650 in proper Euro spec (not Japanese / US 110v version) One could write reams on the benefits of Static induction transistors or Vertical Field effect transistors (V-Fets). Just do an internet search if thats new to you. (Too expensive to produce & too hard to use, seems to have been their death knell) But... V-FETs - Sony went off and developed a transistor that worked like a Valve/Tube = Result a transistor amp that sounds like a tube amp! So these are *bit* famous for their musicality, among other things. Only problem is, theres getting less and less of them because some common diodes in the associated circuit have a tendency to die, taking the whole merry show with them. Actually, Sony went off and re-invented the wheel several times. Not only is the Output stage V-fet; so is the phono stage, very specifically aimed at turntable users (I am not one) but the 2sk79s are similar to an ECC88 - So you get the idea by now... This amp has been subject to a full restoration. Documented on DIYAudio but in summary: Those diodes replacedElectrolytic caps replacedClippy speaker terminals changed for banana typesFilm caps in the signal pathPSU centre grounding Changes associated with the Dutch service bulletinPotentiometers CLEANED Above all, re-biasing of the output devices I cant post the link to the article dont think, (even though I wrote it) so message me for a link if interested. The TA-4650 is very similar to the TA-5650 but without the paralleled output devices (2SK60 & 2SJ18), so lower power, but potentially cleaner sound. TBH I cant tell the difference Downside - see photos of top edge of the facia, I hadnt really seen these, but not mint externally. Any questions please ask, this is already a long ad Andy The inevitable small print. (Please do read this before bidding, as unfortunately it can be necessary to spell this out) More information? Firstly, if you want any more info then please ask as many questions as you like before bidding, I want the winning bidder to be happy with their purchase. BiddersWe all have to start somewhere, so I welcome bids from people with 0 feedback but please e-mail me first so i know youre a real, live person. Same goes if you have a lot of negative feedback. Buy it now?If there is a buy-it-now price it means you can buy the item now (do it) ,If not then the auction will run its course once a bid has been placed. Please respect other e-bayers and don’t PM me with an offer unless the auction is set up that way. Non payersDon’t. It’s not clever, and I have to report it to e-bay to recover listing fees. Payment:Payments managed by e-Bay. Cash / Personal cheque / PO is fine but until the funds are successfully cleared the item remains my property and won’t be sent. As with most people I appreciate prompt payment of whatever type but insist that it’s made within 7days unless agreed. If you are mailing your payment please let me know Postage:I always send with insurance. No exceptions. It doesn’t add that much but covers everyone in the event of a mishap. I aim to post as soon as possible after cleared payment but sometimes working gets in the way. Worst case should be the Saturday after payment. Mostly itll be sent Parcelforce 48, or similar. Never seem to make any money on shipping Destinations:UK only. Why? because postage even to Europe is horribly expensive, complicated by customs and would be undertaken at your risk. I will not ship this item outside of “Europe” under any circumstances. Hey by all means ask just dont be offended when I ignore your message :) Warranty:No warranty is expressed or implied. I am a private individual, not a shop. I simply do not have the resources to back up any warranty. Take a look at my feedback I’m not here to rip anyone off.

All goods are checked for function before they are sent and serial numbers noted. Please bear this in mind when bidding.

Hi You probably know a lot about F7, if you need more, please look here: http://www.thevintageknob.org/sony-TA-F7B.html The amplifier has been completely restored 2 years ago and since than it is working flawlessly. As mentioned, it has been restored to the last piece, mastered by the man who wrote many texts for the vintage knob site. More info by questions. Hooked with separated preamplifier (like I did with Sony TA-E86) the sound is even better). This is a truly gem of integrated amplifiers, in this condition and unique Vfet sound that should be playing few decades more without problem. Any question wellcome, the packing will be done with maximum care.SHIPPING for EU is 50 Eur, other countries please ask before purchase, thanks. Video here https://youtu.be/hSHNfkLP5OA ...................................................................Sie wissen wahrscheinlich viel über F7. Wenn Sie mehr benötigen, schauen Sie bitte hier: http://www.thevintageknob.org/sony-TA-F7B.html Der Verstärker wurde vor 2 Jahren komplett restauriert und funktioniert seitdem einwandfrei. Wie bereits erwähnt, wurde es bis auf das letzte Stück restauriert, gemeistert von dem Mann, der viele Texte für die Website mit Vintage-Knöpfen geschrieben hat. Weitere Informationen bei Fragen. Mit separatem Vorverstärker verbunden (wie ich es mit Sony TA-E86 gemacht habe) ist der Klang sogar noch besser. Dies ist ein wahres Juwel unter den integrierten Verstärkern, in diesem Zustand und mit einzigartigem Vfet-Sound, der noch einige Jahrzehnte problemlos funktionieren sollte. Wir freuen uns über jede Frage, die Verpackung erfolgt mit größter Sorgfalt. Der Versand in die EU beträgt 50 Euro, in andere Länder bitte vor dem Kauf nachfragen, danke.
