Missing back plate EL-84 adapter installed, can run 6V6 too. Clean channel sounds incredible when turned all the way up. Overdrive channel is loud, I played a couple of small shows with the amp and it kept up. VHT chromeback speaker in closed cabinet. In my opinion the amp sounds better with the el84 tube since the chromeback speaker is mid heavy.

### Vintage Western Electric Tube Power Supply / Amplifier Chassis – Featuring TRANS D-163046. Up for sale is an incredibly rare, untouched vintage Western Electric power supply and amplifier chassis assembly from the late 1940s/1950s Cold War era. Originally engineered for the heavy-duty Bell System long-distance carrier networks, these industrial grey chassis are globally renowned today as the ultimate foundation for building custom luxury tube preamplifiers, phono stages, or mono-block guitar tube amps. This unit is a complete goldmine of original, high-grade Western Electric iron and components that are highly sought after by audiophiles worldwide. #### KEY HIGH-VALUE COMPONENTS INCLUDED. Main Power Transformer: Western Electric TRANS. D-163046 (Legendary nickel-iron Permalloy core with pure copper windings).

The other components, transformer blocks, and terminals are visually intact. Freshly recovered from a closed local estate storage cleanout. This is an incredibly heavy, dense block of industrial steel and copper. We take packaging seriously.

This is a General Electric “Stereo Classic” Model RG-1000 Remote Control Unit, made in Auburn, NY in the early days of home stereo. It’s a passive accessory with ganged volume and balance potentiometers on a 30-foot cord, so you can adjust both from your chair. GE built it for its Stereo Classic tube amplifiers. Per the instructions, it also works with other amps that have a tape or preamp output, or with a pair of mono amps such as the GE PA-20. The unit has a textured aluminum faceplate with chrome trim, ebony knobs and base, and the GE Hi-Fi branding. The cord has its original L/R marker tags, and the yellow factory twist ties are still in place. Tested: Both potentiometers check out with a multimeter, showing smooth, continuous resistance sweep across volume and balance with no open spots. It has not been tested in a live audio system. Condition: Unit is clean, with bright chrome and good faceplate graphics Cord is supple, with no cracks or splits noted Original box shows edge wear, corner tears, and a detached end flap (included) Instruction sheet is complete, with fold wear and light toning, and a small paper loss on the illustration. Supremely Rare in this condition!

Vintage EICO HF-12 12-watt mono tube amplifier, previously modified from its original hi-fi configuration for apparent guitar/instrument amplifier use. This is an interesting restoration or further-conversion project for a tube guitar amplifier builder or vintage audio enthusiast. CURRENT CONFIGURATION – Original EICO HF-12 chassis, enclosure and transformers. Original four-position input selector removed and replaced with a front-mounted 1/4-inch input jack. Three remaining front controls: volume, bass and treble. Original rear audio inputs removed. Rear 1/4-inch speaker output jack added. Original speaker terminal strip remains, with altered connections. The 8-ohm terminal is presently unwired. Original decorative front faceplate is missing. Replacement Mallory electrolytic capacitors installed. Three-prong grounded-style power cord installed, but protective grounding has not been verified as satisfactory. Other previous wiring and component changes are visible. ELECTRICAL TESTING PERFORMED The amplifier has NOT been powered up or audio-tested. Resistance and continuity measurements were performed with a multimeter. Output transformer: – Primary end-to-end: approximately 341 ohms – Primary halves: approximately 187 and 154 ohms – Secondary G-4? : approximately 0.9 ohms – Secondary G-16? : approximately 1.3 ohms Power transformer: – Primary: approximately 40 ohms – Heater winding: approximately 0.4 ohms – High-voltage secondary: approximately 205 ohms total – High-voltage secondary halves: approximately 105 and 98 ohms No open windings were identified in the circuits measured. These are resistance/continuity measurements only and do not establish transformer performance under operating conditions. IMPORTANT ELECTRICAL CONDITION The three-prong power cord was checked for continuity between its grounding pin and the metal chassis. Meter lead resistance: approximately 0.2 ohms – Grounding pin to chassis: approximately 2.5-2.7 ohms The protective chassis-ground connection requires further inspection and verification. The power wiring, capacitors, previous modifications and overall electrical safety have not been fully evaluated. DO NOT CONNECT TO AC POWER UNTIL PROPERLY INSPECTED AND SERVICED BY A QUALIFIED TUBE-AMPLIFIER TECHNICIAN. RESTORATION POTENTIAL The EICO HF-12 originally used a push-pull EL84/6BQ5 output stage rated at 12 watts in its factory configuration. The existing instrument-style conversion offers an interesting starting point for a vintage guitar amplifier project. Actual instrument input characteristics, operating condition, output power and sound have not been verified. The amplifier could also be considered for restoration toward its original hi-fi configuration. This would require sourcing missing controls, connectors and faceplate components, tracing the wiring and making appropriate circuit repairs. Not represented as a working or electrically safe amplifier. Includes the amplifier and installed components as photographed. No additional accessories are represented as included. Please review the detailed photographs of the chassis, underside wiring, transformers, controls and connections.
