The finished board has been burn-in d and can be used directly when you receive it.2. Dangerous voltages may be generated when the circuit is working. Please pay attention to safety.Introduction:6E2 tube magic eye driver board adopts Douk Audio core power technology, more convenient and simple to use, effectively reduces the power consumption of the circuit, and the PCB uses a large number of SMT components.Features:1. Adopting universal DC power supply mode DC (5V-7V), and can also be directly powered by standard USB 5V, such as mobile phone charger or computer USB interface. Can be regardes as the lowest power consumption among the same kinds of products.2. Reasonable optimization of PCB size, reduce the chassis space occupied, the wiring is simple and clear.3. The potentiometer is provided with a level display range adjustment, more convenient to adjust it.4. Built-in secondary signal amplification, higher sensitivity, and adjustable level display.5. Built-in electronic boost circuit, not use the 250V transformer required for traditional driver board, saving more money and space.Parameters:Operating voltage: DC 5-7V or USB 5VPower consumption: ≤3.15W (DC7V) / ≤2.25W (DC5V)Net weight: 60 g / 0.13 lbDimensions: 80*47*22 mm / 3.15*1.85*0.87 inPacking List:1 x driver board with case1 x 6E2 tube1 x USB to DC power cord1 x Signal cable Review: Sehr schönes nostalgisches Gadget - Das Gerät ist eine reine Pegelanzeige und relativ hochwertig verarbeitet. Bei der Anzeige kommt eine Chinaröhre 6E2 zum Einsatz, die ihren Dienst tut. Die Anzeige wird nur mit einer Spannung (5-7V) versorgt, aus welcher die Heiz- und durch vielfacher Spannungsverdopplung auch die Anodenspannung erzeugt wird. Dies gestaltet den Einsatz dieses Gerätes sehr einfach, aber Achtung, auf der mit Acryl geschützten Leiterplatte entstehen an der Diodenkaskade bis 200V ! Auch wird die Röhre im Betrieb bis 120°C warm. Dies gilt es unbedingt zu beachten. Es wurde zur optischen Aufwertung in doppelter Ausführung in einen Röhrenverstäker zur Aussteuerungsanzeige eingebaut. Review: effetto wow - effetto spettacolare,speriamo duri nel tempo. Bisogna stare molto attenti ai bordi della scheda perché si rischia di prendere la scossa ## Features - Magic Eye can be used as an audio level indicator or a VU meter.

Bisogna stare molto attenti ai bordi della scheda perché si rischia di prendere la scossa ### ⭐⭐⭐⭐⭐ Divertido. *by C***N on 6 April 2026* Artilugio maravilloso por su exquisita inutilidad práctica a un precio asequible. Y sin embargo ¡qué encanto el de las barritas fluorescentes de la lámpara de vacío subiendo y bajando como le dictan los acordes musicales! Fácil de montar aunque el cable de alimentación a mí me venía un poco corto. Eso sí: debo señalar un fallo. A mi entender, hubiese quedado mejor si el zócalo de inserción de la válvula hubiese estado rotado 90º. De esta manera, podría ponerse el chisme de lado y visualizarse tanto las franjas luminosas como toda la base con su circuitería. Ahora hay que ponerlo de perfil y esta segunda parte se escaquea. ## Frequently Bought Together - DollaTek Magic Eye 6E2 EM87 Tube Preamp Audio Level Indicator VU Meter, Music Spectrum - DollaTek Mini 2.0 Hi-fi Electronic Stereo Audio Assembled Amplifier Portable AMP 10W+10W 2 Channel Class-D DC 12V Digital Booster Amplifier Board Module for CD MP3 MP4 PC Speaker - DollaTek 50wx2 mini bluetooth 5.0 wireless audio power digital amplifier board stereo amp 3.5mm aux usb --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/374052519-dollatek-magic-eye-6e2-em87-tube-preamp-audio-level-indicator](https://www.desertcart.sk/products/374052519-dollatek-magic-eye-6e2-em87-tube-preamp-audio-level-indicator) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-10*
