    RCA Annapolis

    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.

  • Grundig 2066

    Grundig 2066

    We picked up this 1958 Grundig tabletop radio in non-working condition to restore and retrofit not knowing how well it’d turn out. We replaced its mono speaker with a stereo set from JBL with concentric tweeters and made this radio the overhaul it deserved.

    After installing our custom tuned amplifier we wired the volume control to the orinal 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.

    It’s compact size makes it easy to underestimate  — this thing gets loud while keeping a clear, crisp, hi-fi sound.

    This small radio was spotted in rough condition on ebay, and we had to have it. It’s blonde radio plate made it different enough to take a chance on getting a light, delicate piece online. Sight unseen. It couldn’t have turned any better. We replaced its single speaker with a stereo set by Polk Audio, our custom tuned amplifier and wired the volume control to its orinal knob, while the original buttons for off (“aus”) shut the unit off, and another button acts as an input selector switch. Beautiful little piece to add a touch of elegance to any room, while still connecting to your home WiFi as well as bluetooth and an aux-in in the back.

    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 patine 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 one of our Relikcs Timbre consoles in Omaha.

    Zenith Y960

    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.

    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.
