Up for sale from a recent trade in Balanced Audio Technology VK55 Tube Power Amplifier - In the factory box. From BAT Product sheet: Uses Same High-Current Tube as BAT Flagship Power Amp Intelligent Auto -Bias Design Makes Use Easy VK-55 combines fully balanced design topology with automatic biasing of individual output tubes. Offering a simple upgrade path to monoblock operation, this amp marries performance and affordability in one compact package. By using the same high-current dual-triode 6C33C-B tube employed in the flagship REX II power amplifier, VK-55 delivers the high-current kick required to drive even difficult low impedance speaker loads. VK-55 features an intelligent automatic bias design that adjusts for changing line voltage and aging tubes. The auto-bias circuit also ensures that your VK-55 sounds wonderful within the first few minutes of listening.

The result is a unique combination of fully balanced, all-triode design topology, automatic biasing of individual output tubes, and a marvelously simple upgrade path to monoblock operation – all in a chassis that is more compact than any previous BAT tube amplifier design. Beyond its outstanding musical performance, the VK-55 is eminently affordable as well. COMPACT POWERHOUSE Many of our customers have asked for a smaller and more affordable tube amplifier that meets BAT’s rigorous design standards, while providing the breath of life to music that is characteristic of the BAT sound. For those customers, the VK-55 is the answer to their dreams! Moreover, by using the same high-current dual-triode 6C33C-B tube employed in our flagship REX II Power amplifier, the VK-55 delivers the high-current kick required to drive even difficult low-impedance speaker loads. 55 WATTS PER CHANNEL (STEREO) 110 WATTS PER CHANNEL (MONO) The VK-55 power amplifier is a high-current all-triode design that offers 55 watts per channel in the stereo version or a robust 110 watts per channel as a mono block. The 6C33C-B triode output tube used in the VK-55 Power amplifier offers many times the current delivery of the more common 6550 tube used in many traditional tube amplifier designs. High impedance vacuum tubes like the 6550 require far more complicated output transformers than the low impedance 6C33C-B vacuum tube. Consequently, the VK-55 Power amplifier is quite comfortable driving low impedance loads. You can simply choose the stereo or monoblock version based upon your choice of speaker and room size. The highcurrent delivery of the VK-55 Power amplifier will give you the assurance of driving a difficult load with ease. INTELLIGENT AUTO-BIAS The advanced engineering of the VK-55 power amplifier eliminates the traditional headache associated with most vacuum-tube power amplifiers; the constant need to set and readjust the proper bias of the output tubes. The VK-55 power amplifier features an intelligent automatic bias design that adjusts for changing line voltage and aging tubes, with each output tube having its own dedicated bias circuit. For convenience, these individual automatic bias circuits contain LED indicators that show the status of each output tube. The BAT auto-bias circuit also ensures that your VK-55 power amplifier sounds wonderful within the first few minutes of listening. This is indeed very different from manually biased designs that must be adjusted for their thermally warm set point - and thus sound too cold and clinical before their tubes are fully warmed up. INTELLIGENT POWER UPGRADE The VK-55 power amplifier is easily upgraded from the stereo version to monoblock configuration. Unlike competing designs, there is no need for the user to trade their amplifier in to obtain more power. With the VK-55 power amplifier, the user will simply convert their existing VK-55 to a monoblock, and then order a second VK-55 monoblock to match. Technically, the stereo to monoblock conversion is accomplished by simply paralleling the inputs and outputs. This means that “the sound” only gets better as both current delivery and power output go up by a factor of two, and the monoblock noise floor drops appreciably as well. SUMMARY The VK-55 offers the midrange clarity, power, and dynamics that have made BAT one of the most respected brands in high-end audio. The VK-55 is truly able to present a magical open window to the original performance - and a closer emotional connection to the artistry of music. Cosmetically, you can probably find some signs of wear here there from used, but overall it looks good condition. This unit has been tested working properly on all functions. Amplifier comes with Comes with Sovtek Russian 6C33C and 6SN7GT Tubes and owner manual, power cord, shipped in factory box. Buyer will pay actual insured shipping Costs and signature required on delivery. For quick supports can be reached, 9167.79.9889. **If you have any questions, please feel free to contact me**

KECES BP1200 1200VA Balanced Isolation Power Conditioner. – sehr selten – stabile Stromversorgung für 4 Geräte. Power supply Funktionierte bis zuletzt tadellos und wirkt Wunder!Auf der Keces Webseite kann man sich Specs und Testberichte ansehenOriginalkarton vorhandenZustand siehe BilderVersandkosten wg über 10kg... Siehe meine anderen Auktionen – see my other auctions For international bidders - please ask before bidding - postage costs may vary by country Sales from private, no guarantee, no returnSee pictures – if questions please ask before the auction has ended. Bitte vor dem Bieten lesen. Allgemein:In den kommenden Monaten werde ich einen Nachlass, einen Teil meiner Sammlungen und diverse andere Artikel verkaufen – wenn ich durchhalte, sind es viele hundert Produkte.Alles wurde in den letzten 30 Jahren gesammelt und sorgsam trockenen, beheizten Räumen aufbewahrt. Wir sind ein Nichtraucherhaushalt. Wir hatten und haben keine Haustiere. Jeder einzelne Gegenstand wurde gereinigt und bestmöglich erhalten. Den Zustand entnehmen Sie bitte den Bildern. Siehe meine Bewertungen in den vergangenen 22 Jahren – nie neutral oder negativ.Sollten trotz allem Fragen bleiben, bitte ich Sie diese vor der Auktion an mich zu richten. Trotz der Anzahl der Bewertungen und der Dauer meiner Ebayzugehörigkeit habe ich es immer als Hobby betrieben und bis auf ganz wenige Ausnahmen mit Betrugsverkäufern verlief es in 99% der Fälle ok. Ich bin kein Shop und auch nicht Amazon, dies bitte ich im Hinterkopf zu behalten. Nur wer freundlich und respektvoll mit mir kommuniziert wird eine Antwort erhalten! Versand:Grundsätzlich versende ich nur im versicherten Paket der DHL zum Selbstkostenpreis, was bei einem 2KG Paket 1,50 Mehrkosten gegenüber einem unversicherten Päckchen ausmacht. Wer dies nicht möchte, den bitte ich hier nicht zu bieten. Davon mache ich auch auf Nachfrage keine Ausnahme.Aufgrund von negativen Erfahrungen mit EBAY gelten außerdem folgende ergänzende Bedingungen. Kommt die Sendung zurück, weil nicht zustellbar oder die Sendung wurde nicht beim DHL Shop abgeholt, werde ich eine 2. Zustellung vornehmen, sobald das Versandentgelt unaufgefordert (!) ein zweites Mal bezahlt wurde. Nach 14 Tagen erlöschen Ansprüche auf eine 2te Zusendung, wenn nicht vorher anders mit mir abgestimmt.Dazu ergänzend – fast alles was aus dem Nachlass verkauft wird ist 20 oder mehr Jahre alt. Selbst wenn Produkte hier tadellos funktioniert haben, ist nicht ausgeschlossen, dass der Transport Schäden aufgrund Materialermüdung o.ä. hervorruft. Dieses Risiko ist vom Käufer zu tragen oder er muß die Ware abholen. Ich werde bestmöglich verpacken und es gab diesbezüglich noch nie Kritik oder beschädigte Ware. Trotzdem hat der Käufer bei Entgegennahme der Ware darauf zu achten, dass der Karton unbeschädigt angekommen ist. Ist dies nicht der Fall muß dies vor Ort reklamiert werden, denn nur dann greift der Versicherungsanspruch gegenüber der DHL. Bezahlung:Es sollte heute selbstverständlich sein, dass man gekaufte Ware sofort bezahlt.Ist die Ware nicht innerhalb von 7 Tagen bezahlt - Paypal oder Überweisung – werde ich weitere Kommunikation dazu an das Ebay Mahnverfahren übergeben. Privatauktion: Bei dieser Auktion handelt es sich um einen Kaufvertrag von Privat an Privat nach § 13 BGB. Die Auktion erfolgt unter Ausschluss jeglicher Gewährleistung, Garantie und Rücknahme. Gemäß § 447 BGB gilt, dass mit Übergabe an den Versand die Gefahr auf den Käufer übergeht -> deshalb immer versicherter Versand. Laut dem neuen EU-Recht muss dieser Zusatz unter jeder Online-Auktion stehen, ansonsten haftet der Verkäufer ein ganzes Jahr für die verkaufte Ware. Dies steht aber oft in keinem Verhältnis zum Wert der Ware. Bieten Sie bitte nicht, wenn Sie mit diesen Regeln nicht einverstanden sind.
