Rare vintage custom-built vacuum tube mono amplifier featuring a highly desirable Acrosound Ultra-Linear TO-300 output transformer along with Raytheon transformer components. Likely dating to the 1950s hi-fi era. This amplifier was previously paired with a Garrard turntable as part of a vintage custom mono hi-fi setup. Included is the original/custom wood cabinet featuring an open-sided ventilation design, giving the amplifier a fantastic mid-century custom hi-fi appearance. Also includes the vintage cables shown in the photos. A very interesting piece of early high-fidelity audio equipment with strong appeal to vintage tube audio collectors, restorers, and DIY hi-fi enthusiasts. Listed as parts/not working due to age and inability to fully test. Unit powers on and tubes illuminate. I was told it was working when originally acquired. I do not currently have the proper equipment/setup to fully test functionality. No smoke or burning odor observed during brief power-up. Includes custom wood cabinet/case shown. Includes cables/wiring shown in photos. Cosmetic wear, dust, oxidation, scratches, and age-related patina present throughout. Some handwritten/taped impedance markings on rear panel. Includes tubes currently installed as shown. Heavy transformer-based construction. Please review all photos carefully for condition and completeness. Acrosound Ultra-Linear TO-300 output transformer. Raytheon transformer components. Multiple vacuum tubes. Separate FIL and B+ power switches. Rear speaker impedance taps marked 4? / 8? / 16? RCA input connections. Custom aluminum chassis construction. Period custom wood cabinet with open ventilation sides. An excellent candidate for. Vintage hi-fi restoration. Tube amplifier projects. Mono listening systems. Parts or restoration. Display in a vintage audio collection. A scarce and visually striking piece of vintage tube audio equipment with desirable Acrosound iron. Thank you for looking.

Pulled from a WORKING pair of W3M tube amplifiers, driving 6L6GC pairs in each. Amps (which are not included, nor are the tubes) were gone through and recapped last year. I bought the amps for the tubes, as I needed them. Parting out now the amplifiers (and other items from the lot). 1 One of them was custom mounted to the chassis, as they relocated one of the caps. They bent the tab that mounts the transformer to the chassis. I tried to bend it back, but it is solid. They must have a metal bending tool. You will need to rebend. I tried with a strong set of grips, and while it moves, I just didn’t trust myself. Obviously not an issue that affects performance, just the way it is mounted. If you are handy, or have some experience bending metal, you can certainly get it back. 2 other one had some wax on the underside, and the wires. Likely a bad wax cap over the years melted. You can likely wipe it off… I did, and some came off. Didn’t spend too much time with it though (like literally 10 seconds). Should clean up nice. These are superb, working TO-300 transformers. Pairs are getting super hard to find (as are singles). Very heavy, will be double boxed to ensure they make the transit.

A Very Nice Used Vintage Tube Amplifier Parts With Acrosound Ultra-Linear Transformer Type TO-300. I do not have the separate power supply and did not tested the unit. 2 Tubes are 5692. In great condition for the age. Very clean inside out. I do not know much more about this amp Altec. I got this item in an estate sale. The last owner was a serious collector & an. I bought a large amount of tube amp, preamp, reel to reel etc. I sanitize everything I sell. Please look at the pictures carefully to get an accurate description. And feel free to ask questions. Please contact me with any issues prior to leaving negative/neutral Feedback or low detail ratings. As I will always do my best to solve any problems that may come up!

This is not available for international buyers. I will almost certainly send it in two separate packages since one piece is extremely heavy. You get all three pieces as seen in the first photograph and then I give you a lot of detailed photographs of each piece. There is a complex cord that looks like the pin output of a vacuum tube that goes between two of the pieces. Very rare amplifier setup with separate control module and preamp output stage. The backbone of this system is the valuable TO-300 transformer which is labeled as an 18 Watt output variety. There’s a complex interconnect cord as well as a four prong cable that connects the two units together. I don’t dare test this or plug it in because I know a lot of people like to test these on a variac. I give you a lot of photos there is some discoloration and wear on the metal chassis of both units but the toggle switch moves freely into its three positions and the tube plugs don’t look cracked or damaged. Half of the knobs on the control unit turned freely and some have meaningful resistance. You can see some framing of the four prong cable but you’ve got multiple RCA outputs and a power lamp indicator the primary tubes on the larger unit are ge 61-43 / 188-5.
