Vintage Tube Amp

Up for sale is a rare RCA MI-26155 Distribution Amplifier, a foundational piece of mid-century broadcast technology. Manufactured by the Radio Corporation of America in Camden, N. These units were the gold standard for signal distribution in high-end television and radio studios during the late 1940s and 1950s. Provenance & History: This unit is believed to have originated from a CBS television station. While no formal paperwork is included, the industrial gray finish and “DA31″ inventory tagging are consistent with the equipment standards used by major networks during the Golden Age of Television. Tube Complement: Designed for (5) 6AC7 and (5) 6AG7 vacuum tubes (tubes not included). Chassis: Heavy-duty rack-mount steel construction. Condition: External: Original industrial paint shows honest wear, scratches, and patina consistent with age and professional use. The original RCA “Meatball” logo and nomenclature plate are remarkably well-preserved and legible. Internal: The underside wiring appears largely original and intact (see photos). This is an excellent candidate for a “hollow-state” restoration or a centerpiece for a vintage broadcast display. Dimensions: Approximately 19″ W x 12″ D x 8.5 H. It is untested and has not been powered on to protect the vintage transformers and components. Please review the high-resolution photos carefully, as they are the primary description of the item’s physical condition. It will be professionally packed and double-boxed to ensure it arrives safely.

The Lazarus Hybrid Amplifier is a rare and highly sought-after hybrid stereo power amplifier designed by Greg Miller and built in North Hollywood, California. It runs a cascode-connected 6DJ8 dual triode input stage driving complementary MOSFET output devices, with all circuit voltage gain derived from the tube front end and no overall feedback loop – a topology that delivers the warmth and dimensionality of tubes with the authority and control of solid-state. Power output is rated at 50 watts per channel into 8 ohms in Class A, doubling to 100 watts into 4 ohms and 200 watts into 2 ohms, with the ability to bridge to mono for 200 watts into 8 ohms. Owners consistently praise its ability to reproduce the deepest soundstages they’ve encountered, with zero listening fatigue even after extended sessions – a testament to the amp’s fundamentally musical character. Built like a tank in a 2U rack-format chassis weighing 35 lbs, the H-1A is an extraordinarily rare piece of American audio history that competes comfortably with amplifiers costing many times its original price. In good cosmetic condition, has some scratches/marks, see pictures for details. The unit has been cleaned inside and out to remove dust, debris, and surface blemishes. The interior was carefully vacuumed using a soft-bristle brush to ensure gentle yet effective dust removal without damaging internal components. Only comes with what you see in the pictures which includes the unit itself only. Unit powers on but the DC offset measured too high for safe use and testing so it has been deemed a for parts/repair unit. The unit was not tested further after the DC offset was measured. Please note the unit does not include tubes. At HTF Audio, we put care into every unit we list-cleaned, tested, and ready for its next home. Unlike general resellers, we focus mainly on audio gear, so everything we sell gets hands-on attention, from detailed functional testing to cosmetic work.

The Conrad-Johnson Premier Four is a revered high-power tube amplifier from the early 1980s, delivering around 100 watts per channel using a quartet of E34L output tubes per channel in a fully dual-mono design. Built with CJ’s hallmark minimalist philosophy and premium components-such as polystyrene and polypropylene capacitors-the Premier Four offers a lush, dynamic, and spacious sound with outstanding low-end control and airy highs. Its massive transformers and rugged chassis underscore its audiophile pedigree, while the sonic presentation remains warm, musical, and effortlessly engaging. Still sought after by serious tube aficionados, the Premier Four is a standout in Conrad-Johnson’s legacy of combining tube warmth with real-world drive and authority. We don’t just power test our units and then write “tested, works” in the title (like a lot of other sellers we see). We usually always include a video unique to every item for you to see for yourself (for working units). Apart from that we put work into every unit, specializing in cosmetics which ranges from cleaning pots/switches to polishing the windows on receivers and conditioning the wood on wooden cases and speakers. In good cosmetic condition, has some scratches/marks, see pictures for details. Unit has been cleaned to an extent but could use a better cleaning. Only comes with what you see in the pictures which includes the unit itself only. Please note some tubes are missing. Unit has been powered up using a variac so power is confirmed working but we did not test past that due to some burnt internal components we noticed while inspecting the amp around the tube bases. Highly recommended to use a professional tech for repair. Upon purchasing this item you accept and agree that you have reviewed all of the pictures and understand that what you see is what you are getting.

This amp was last used for guitar (& bass) about 30 years ago- sounded awesome with 412 cab- damn loud & excellent distortion tone- uses 4 6L6GC tubes for some real power! Has some scratches & minor dings- but overall nice looking-see pics for cosmetic condition. There was a bias & ac switch problem and it was shelved years ago. Been stored since- no tubes included. I’m cleaning out my storage area & some of these things gotta go. The transformers & switches all test good.

Consider that if you have an allergy. Everything pictured is included, no screws for the cover.
