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.

Vintage Executone P 300. This is an estate find. Uses four 6L6GC tubes, so it will probably be pretty powerful. This information seems correct but I don’t have enough expertise to confirm. High power Push Pull Parallel with four 6L6GC outputs. Dual 5U4GB rectifiers, one 6SN7GT driver and two glass bottle type. This amplifier has one speaker tap. I believe it is good to 4-8 ohms no lower. It also includes 35 volt and 70 volt line operation as well as the parallel. These amplifiers where built to run 24/7. I believe the AUX input has a volume level preset control and is a direct input to the. Main amp for use with an external preamp. This amplifier also has a phono and. Transformer mic matching input which appear to be controlled from the front panel voice pitch/voice volume, music treble/bass, volume. Appears unmodified with very little. Use, but I can’t guarantee that. Look at the pics. Made in the USA including transformers and choke. This I s a powerfull amp, probably 40w-100w, and likely closer to the middle to higher end of that range. This is an amazing find in very nice cosmetic condition. It also could be used to make an amazing vintage guitar amp. Note the immense transformers! Lots of iron makes for good sound! Executone was made in New York USA. No bottom cover, untested. What you see in the pictures is what is included. If it isn’t shown, it isn’t included in the sale. I have experience packing and will pack it properly. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps”. The seller is “brucejoan93″ and is located in this country: US. This item can be shipped to United States.
