Vintage Tube Amp

For parts rebuild non working. Missing tubes and knobs. Was gonna restore it but EL-37 tube is way to expensive. Some caps have been replaced. ORIGINAL FISHER POWER CORD.

Here is an impressive-looking Stromberg Carlson AU-33 6L6 tube amplifier. Please examine all actual item pictures carefully to understand the details of the item. It will be well packed and insured. “Power cable dry rot”. Thanks again for looking.

I’m letting go of a few things from from my collection, including this Heurtier HSM 6 watt vintage magnetic film tube amplifier project. Will make a killer make killer guitar amp! If you like the Filmosound amps, this is right up your alley. The amp needs typical updates like new. Servicing, checking/replacing capacitors as needed, and desired mods/conversion. Comes with pictured vintage tubes.

EICO HF-81 Integrated Tube Amplifier – Restoration Candidate – Working Iron. Some units are plug-and-play. This is not one of them. This EICO HF-81 is a largely original example and should be viewed as a restoration project. The transformers appear healthy, but the amplifier will require electronic servicing for stable, long-term operation. This is for someone who will selectively change parts for stability but retain the sonic character the HF-81 is famous for. Operational Status (Please Read Carefully). Powered up slowly on a Variac. Output transformers pass signal. Video included demonstrating that both channels produce output. One channel is weaker and exhibits distortion. The stronger channel distorts at high volume. Power switch (integrated into treble knob) does not function properly. Unit is likely running on original capacitors. Given its age, full recap and restoration is recommended before regular use. Tube Complement (Installed & Working). The original Eico factory installed tubes tested weak or shorted and were replaced with. Quad Sylvania EL84 / 6BQ5 – New old stock (NOS) and new in box (NIB). Tubes are functional, but the distortion issue suggests underlying circuit components (likely caps or resistors) require attention. Classic gold faceplate with vintage wear. Appears largely unmodified internally (based on current inspection). Why This Is Worth Restoring. The HF-81 is widely regarded as one of the most musical EL84 integrated amplifiers ever made. Properly restored examples command strong market value and are known for. Balanced push-pull EL84 output. Highly respected transformer set. The transformers are the heart of these units – and this one passes signal. Collector seeking original platform for rebuild. If you’re looking for a fully restored, daily-use amp, this is not that listing. If you want a strong foundation with working iron and upside potential, this is an excellent candidate. Will require recap and service. Distortion present in one channel. Power switch requires repair. See video for operational demonstration.

Both are in excellent NOS condition, and the date codes match. Although the original boxes are a little crinkled and bent up. Balanced, and results are displayed in the photos. The test result stickers will be included inside the box but not applied for any collectors who want to preserve originality. See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.

FISHER X-202C INTEGRATED AMPLIFIER AUDIO OUTPUT TRANSFORMER PAIR as pictured, they’re pulled, in good condition (tested) The shown soda can is using as relative scaling purpose only.

I’m letting go of a few things from from my collection, including this Hoffman A 300 vintage tube amplifier project. This old tube radio chassis has been stripped of the radio components, and is ready to convert into a killer guitar amp! Has the right voltage range for a 5C1 Octal Champ, either use the 6×5 rectifier or convert to diodes to raise the B+. Power and output transformers are there, and tube sockets. Needs your own circuit installed – and typical updates like new. Servicing, caps, desired mods/conversion, and tubes if you want different than stock.

I did not plug it in, because I don’t have the proper way to use this. So I will not plug it in and turn it on.

Vintage UTC Linear Standard MLF tube amplifier, manufactured circa 1954 by United Transformer Corporation (UTC). This is an extremely rare mid-century hi-fi amplifier built during UTC’s golden era and designed around original UTC transformers throughout. Units like this rarely come up for sale in complete form and are highly sought after by collectors, restorers, and transformer enthusiasts. I do not have the proper equipment to safely power or test vintage tube electronics, and no attempt has been made to plug this unit in. Due to its age, please assume it will require service, restoration, or parts replacement before use. No guarantees are made regarding functionality. Cosmetically, the unit shows normal age-appropriate wear and patina consistent with a 1950s amplifier. There is no obvious major damage visible. Please refer to the photos carefully, as they are considered part of the description and show the exact condition of the item. This model is documented on Radiomuseum and recognized as a high-quality Linear Standard / Williamson-style hi-fi amplifier built to showcase UTC transformer technology. Additional reference information can be found here. Serious buyers who are familiar with UTC gear will appreciate what this is.
