    One of our favorite consoles, which we continuously try to get more of, is certainly the RCA Annapolis. With its curved front and slatted speaker grilles, this console’s design bleeds MidCentury Modern. No console have we restored and retro-engineered more of than the Annapolis. At one point, we were working on three of them at the same time and discovered that no matter how similar they look, they all sound different and therefore require just as much individual attention.

    Built and sold over the course of a few generations, through which the main cabinet remained unchanged, with just a couple of tweaks and two different amplifiers (as well as a larger model — dubbed “The Manhattanite”, that has somehow eluded our attempts to restore one), it is still one of the most iconic stereo console designs of the 1960’s.

    Most RCA Annapolis’ we’ve retro-engineered were built between 1965 and 1969.

    All of our consoles, speakers and radios go through an extensive bespoke tunning using a professional calibration microphone and computer software, which then gets written into the amplifiers DSP (Digital Signal Processor) firmware. This is done in order to achieve outstanding fidelity and performance.

    This vintage Grundig radio showcases our transformation of the 1958 Grundig 2066 into a modern streaming machine. By integrating JBL speakers, custom amplification, and wireless streaming, we preserve the charm of vintage design while delivering high-fidelity performance.

    We picked up this 1958 Grundig tabletop radio with a blown (single) speaker and burnt out amplifier to restore and retrofit not knowing how well it’d turn out.

    Inside the Grundig 2066: From Mono to Stereo

    Usually preferring buying broken down radios, we never know what to expect. Especially when ordering online. In this case, it only took a deep cleaning and some light buffing at Vintage Source to make its wooden case shine. The audio however, was a different story.

    Every Vintage Grundig radio retrofit we build is tuned for clarity, warmth, and reliability and this one is no different. We started by replacing its mono speaker with a stereo set from JBL with concentric tweeters.

    After installing our custom tuned amplifier we wired the volume control to the original volume knob and kept the original clacky buttons performing some modern functions — off, on and input selection, cycling through Wi-Fi Streaming (for Spotify Connect, Apple Airplay and more), Bluetooth, and even an aux-in port in the back.

    This custom retrofit honors the Grundig legacy while delivering modern performance and convenience. But don’t let it’s compact size fool you, it gets loud while keeping a clear, crisp, hi-fi sound.

    This Vintage Körting fully retrofit radio transforms the Neckermann 1035/60 into a modern yet elegant tabletop streamer. Built in the early 1960s, the compact radio arrived in rough condition after spotted on eBay. Its blonde tuner plate and understated cabinet made stood out enough to take a chance, sight unseen.

    Following a full cabinet refinish by Vintage Source, we focused on preserving the original look and dial glass. Inside, the mono speaker was replaced with a stereo set from Polk Audio, paired with a custom-tuned solid-state amplifier engineered for clarity and warmth. The original volume knob now seamlessly controls the new amp, while the factory buttons remain functional: the “aus” button powers the unit off, pressing any other button switches it on and the far-right button has been modified to act as an input selector.

    Polk Audio Drivers and Solid-State Amplification

    This retroengineered Körting now supports Bluetooth, Apple Airplay, Spotify Connect, Roon and a wide range of streaming services via Wi-Fi. To support legacy devices, we discreetly installed an aux-in port on the rear panel. This addition enhances compatibility with older sources and allows users to integrate vintage gear without sacrificing convenience or quality. It complements the system’s modern streaming capabilities by offering a tactile, analog option for purists and collectors alike. Thanks to a redesigned internal layout, the stereo imaging remains clean and balanced with minimal resonance, making it ideal for small spaces without compromising fidelity.

    Whether placed on a shelf, sideboard, or desk, the piece adds a touch of elegance while delivering modern functionality. In essence, it reflects Acvstica Audio’s commitment to preserving design heritage and elevating sonic performance.

    I’ve wanted to own and restore a set of these speakers since forever. And I finally got the chance. I definitely overpaid for them, and they were the higher end model that included a vacuum tube amplifier inside each. Definitely the earliest powered speaker I’ve ever known of. The date I found in them was sometime in 1959. I wanted to replace the speaker cloth, but none of my sources had anything nearly as cool as the original, so we left the grime and patina as it was and gave them a new set of carbon fiber woofer speakers with AMT tweeters as well as a power amplifier with our custom tuning. They sold before I could even think up how much should we ask for them. Fortunately though, they went to an amazing family that also owns a Relikcs Timbre console in Omaha.

    Few consoles capture the Mid-Century Modern aesthetic quite like Zenith’s Louvered Door consoles. We’ve restored several over time and always admire the timeless elegance of these designs. Though not particularly rare due to their long production run, a well-preserved example remains a true statement piece.

    Over roughly a decade of production, Zenith continually refined its models while maintaining the signature look and feel—wider, deeper cabinets, with or without open-reel tape decks, and Danish or Modern-style bases.

    We currently have three different cabinets, including two of the larger Y960s. One is a YT960, displayed unrestored at Vintage Source‘s showroom. Unfortunately, its lifting R2R tape deck was removed long before it came to us, so we’ll repurpose the space as a storage cubby. The third console is a more compact model that keeps the same overall aesthetic.

    • Audiophile-grade record player

    The console pictured here is a retrofit we had refinished by what is now Vintage Source, back in 2022.

    The Zenith X930, built in 1966 specifically.

    Zenith provided little documentation regarding model variations and production dates for this design style, but we’ll continue updating this page as we uncover more. We aim to be a reliable resource for verified information on these consoles.
    Currently, our collection includes a YT960 (sans tape deck), a Y960, and a smaller unidentified model, all boasting Zenith’s iconic louvered doors

    Every console, speaker, and radio we restore undergoes extensive bespoke tuning using a professional calibration microphone and advanced software. The resulting data is programmed into the DSP (Digital Signal Processor) firmware, ensuring exceptional fidelity and performance.
