Tested typical functions and appears to work well. Its not perfect but its perfectly usable. Please see pictures and video for cosmetic and functional condition. Usable as is but if you want it perfect you may want to take it to your favorite technician. That being said it will be sold as is with no returns refunds warranty or guarantee. Only the receiver is included in the sale. Everything else in video is for demonstration purposes only. Will ship carefully packaged by me, thank you. What follows is a review for the former model released by the Chicago tribune in the 80s. Some details may not pertain to this model but it should give you an idea what to expect: Protons new AI-3000 is not just one particle but the whole atom of a stereo system. Its nucleus is compact and well constructed. It includes an AM/ FM stereo tuner, a stereo cassette deck that records on any type of tape and has Dolby B noise reduction, a programmable compact disc player and a 22- watt-per-channel amplifier. Proton surrounds this nucleus, which is the size of a fat receiver, with two compact satellite speakers. Multicolored lights and buttons, plus an amber, green and red LED (light-emitting diode) display, spruce up the basic black front panel. The supplied remote control commands the units basic functions. The Proton goes where few stereos have gone before. It fits in the den, dorm room and bedroom. Somehow Proton makes a rectangular black box look good. The reason may be in the shape of the cassette and CD windows, the layout of controls or the fold-down door at the bottom that hides the secondary controls. Even the curved, bent and ribbed remote bespeaks high tech and high style. After removing the two transit screws that lock down the CD mechanism and connecting the speakers, you immediately have music. The control layout, both on the front panel and the remote, eliminates confusion. The shape, color and position of the buttons logically define their functions. The CD player loads only when the 3000 is switched to the CD mode. A button toggles the display between track/index number and elapsed time. The player responds to commands reasonably rapidly, but the mechanism is audible during play. Another modest drawback is that you cant hear what youre scanning. The player lacks direct track access; you program up to 20 tracks by using the - and + buttons. You cannot program a single track more than once. The player ignores index points, which are track subdivisions. The cassette deck auto-reverses in both play and record modes and automatically senses the type of tape you insert. Proton intelligently hides the Dolby off button with the secondary controls, recommending that you leave it switched on permanently. The manual explains that most prerecorded tapes now come encoded in Dolby B and tapes you record should also be recorded in Dolby for optimum sound quality. A microphone jack permits live home recordings if you have a mike. The tuner section delivers highly respectable reception. Even in fringe areas, it pulls in quite a few stations with only the folded dipole antenna, which is a T-shaped wire provided with the unit. Although the AI-3000 omits a turntable, it does contain phono inputs that accept a magnetic phono cartridge; so you can always add a record player. The most annoying feature of the unit is its bright-green pilot light, which remains illuminated even when the Proton is off. If you plan to use the AI-3000 in a bedroom, you might want to cover it with a piece of opaque tape or get a service technician to snip its wires. The printed specifications of the AI-3000 wont impress avid stereophiles. Yet the whole sounds better than the sum of its parts. You can improve the sound further by substituting better speakers than those provided. Its $1,200 price really makes the AI-3000 sound terrific. Adjusted for inflation, this is a bargain when compared with all-in-one compact systems of a decade ago. You can obtain equal performance from a $900 rack system but with less versatility. Try hiding a rack system, or fitting one into a small space. If youre looking for an alternative to conventional stereo/hi-fi systems and cant afford a Bang & Olufsen, check out the AI-3000. You may find it at a discount, making it even more attractive. Proton really knows its electrons.

Vintage Proton AD-300 Stereo Cassette Deck Minor side rust in one spot see pics..its also missing on of the knobs in front..see pics..It power up opens and closes,fast forward and reverse works fine,but when you hit play it just advances the tape forward or backwards...Im not sure why its just started doing that but is probably a minor fix.. thanks for your interest!

Listed as for parts or not working because item has been stored for at least a couple decades and unable to thoroughly test and unfamiliar with the device so I don’t want to guarantee that’s is 100% fully functional and mislead buyers. Also when I click radio nothing was happening. I know shipping is $100 but that’s about how much it costs when I just sold it to another buyer and then I had to refund the buyer. This weighs like 35 pounds and is extremely heavy.

This Proton unit is in good overall physical condition. It powers on and all of the meters/indicators light up. The cassette deck works, the CD player works, and the tuner works (although you will need antennas). It does have some small imperfection - scratches, knicks, etc. mostly on the top of the metal housing. It does come with the original remote control as shown in the pics. FREE shipping anywhere in the continental USA via UPS or FedEx (no PO boxes).

Turns on - that’s all I can confirm works or doesn’t work. For parts or repair

PROTON D1200 Getestet, sauber und in ausgezeichnetem Betriebszustand!!! Beschreibung : Der Hochstromverstärker Proton D-1200 wurde sorgfältig mit Fokus auf Klangqualität entwickelt. Ein sehr seltener Verstärker, gebaut wie die begehrten Monoblöcke von Dynaco McIntosh, Marantz und anderen, aber verpackt in einem kompakten und leistungsstarken Paket. Ob als Ergänzung zu einem vorhandenen Audio- oder Videosystem oder als Teil eines völlig neuen Systems, Sie werden mit Sicherheit die Klarheit, Detailtreue und Leistungstiefe bemerken, die Proton-Produkte unabhängig vom Preis zu den besten der Welt machen. Der D1200-Leistungsverstärker von Proton verfügt über ein Dynamic Power on Demand (DPD)-Schaltungsdesign, das ihm einen außergewöhnlichen dynamischen Headroom von 7,3 dB bietet. Das DPD-System von Proton ist für einige der höchsten Ausgangsleistungen verantwortlich, die wir je von einem Verstärker gemessen haben. Spezifikationen : Ausgangsleistung: 100 Watt pro Kanal an 8 ? (Stereo), 1800 Watt an 2 ? (Mono) Frequenzgang: 20 Hz bis 20 kHz Gesamte harmonische Verzerrung: 0,02 % Dämpfungsfaktor: 250 Eingangsempfindlichkeit: 1V Signal-Rausch-Verhältnis: 120 dB THD bei Nennleistung 0,02 % Lautsprecherlastimpedanz: 2 ? bis 8 ? Abmessungen: 420 x 122 x 395 mm Gewicht: 15 kg IHF-Standard 20 ms Dauer: 540 W (8 Ohm) 1000 W (4 Ohm) 1500 W (2 Ohm) 100ms Dauer: 450 W (8 Ohm) 650 W (4 Ohm) 800 W (2 Ohm) 200 ms Dauer: 380 W (8 Ohm) 500 W (4 Ohm) 520 W (2 Ohm) Über den Klang... Da ich der landläufigen Meinung, dass gute Endstufen „anders“ klingen, nicht zustimme, kann ich zu diesem Thema nicht viel sagen. Bei diesem Verstärker waren die Auswirkungen der Hochpegeltransienten, die häufig das 6-dB-DPD-Licht zum Leuchten brachten und zu Messwerten über 400 Watt führten, geradezu atemberaubend. Nicht viele „100-Watt“-Verstärker können dieses Leistungsniveau erreichen. Der D1200 ist in Schwarz gehalten und verfügt über zwei große Leistungsmesser. Die logarithmischen Skalen der Messgeräte decken einen Bereich von einigen Milliwatt bis zu vielen hundert Watt (in 8 Ohm) ab, und die Zeiger haben eine schnelle Reaktionszeit, um Programmspitzen zu folgen. Auf der Rückseite des Verstärkers befinden sich isolierte Polklemmen-Lautsprecheranschlüsse, Eingangsbuchsen und ein Stereo/Mono-Schalter. Der D1200 ist 16-1/2 Zoll breit, 14-1/4 Zoll tief und 4-1/4 Zoll hoch und wiegt 35 Pfund. Kenner wissen, wovon ich spreche!

Description : The Proton D-1200 high current amplifier has been carefully developed with complete emphasis on the quality of sound. A very rare amplifier constructed like the sought after Mono blocks of Dynaco McIntosh, Marantz and others but put together in one compact and Powerful package. Whether adding to an existing audio or video system or as part of an all new system, you are certain to notice the clarity, detail and depth of performance which make Proton products among the best in the world, regardless of price. Proton’s D1200 power amplifier features a Dynamic Power on Demand (DPD) circuit design that gives it an extraordinary dynamic-headroom rating of 7.3 dB. Proton’s DPD system is responsible for some of the highest power outputs we have measured from any amplifier. Specifications : Power output: 100 watts per channel into 8? (stereo), 1800 watts into 2? (mono)Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.02% Damping factor: 250 Input sensitivity: 1V Signal to noise ratio: 120dB THD at rated power 0.02% Speaker load impedance: 2? to 8? Dimensions: 420 x 122 x 395mm Weight: 15kg IHF Standard 20ms duration : 540W (8 ohms)1000W (4 ohms)1500W (2 ohms) 100ms duration: 450W (8 ohms)650W (4 ohms)800W (2 ohms) 200ms duration: 380W (8 ohms)500W (4 ohms)520W (2 ohms) About the sound . . . well, since I do not subscribe to the popular notion that good power amplifiers sound “different” from each other, there is not much I can say on that subject. However, with this amplifier, the impact of the high-level transients—which often lit the 6-dB DPD light and produced meter readings of more than 400 watts— was nothing short of stunning. Not too many “100-watt” amplifiers can match that performance. The D1200 is finished in black, with two large power meters. The meters’ logarithmic scales span a range from a few milliwatts to many hundreds of watts (into 8 ohms), and the pointers have a rapid response time to follow program peaks. Insulated binding-post speaker connectors, input jacks, and a stereo/mono switch are in the rear of the amplifier. The D1200 measures 16-1/2 inches wide, 14-1/4 inches deep, and 4-1/4 inches high and weighs16 kg. Connoisseur know what Im talking about!
