Audio output transformer products for tube amplifiers are manufactured in Vietnam. Core material is imported from nippon. The wire we use is exported to Europe and America. We use new materials and do not reuse them under any circumstances. The high skills of Vietnamese workers have created products with stable quality measured by the keysight machine system. Recommended for use with 300BSE, EL34SE, 6l6SE… Or bulbs with equivalent impedance and capacity. Inductance at 20Hz: 20 Henry. Total weight 3.2 kg (7 lbs). Bandwidth 20hz – 20khz (-0.7 db). Note : The price for 1 pair as shown in the picture. We ensure careful packaging.

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.

Offered here is a vintage Acrosound Ultra-Linear output transformer, Type TO-310, manufactured in the USA by Acro Electronic Products Co.

The TO-310 is a desirable model for restoration projects and high-quality DIY builds. Metal cover shows cosmetic wear, scuffs, and paint loss consistent with age (see photos). Original cloth-covered leads with typical age-related wear. Leads retain factory number tags, which aid identification. Mounting base is solid and straight. Electrical Checks (DC Resistance). The transformer has been checked for continuity and DCR only using a digital multimeter. Blue stripe? Green stripe: 98.8? Blue? Green: 118.9? Tan #1? Green stripe: 38.8? Tan #2? Blue: 152.9? Tap 1? 2: 0.7? Tap 1? 3: 0.4? Tap 1? 4: 0.4? Readings are consistent with a multi-tap ultra-linear output transformer and indicate intact windings. Continuity and resistance checks only. No signal, load, or in-circuit testing performed. Transformer has not been powered. Genuine vintage Acrosound iron (not a reproduction). Excellent candidate for restoration, tube amplifier builds, or collectors. Please review all photos carefully – they are part of the description.
