1500 watts amplifier for 1.8 to 54 MHz HF linear 50v LDMOS BLF188XR 10 meter

Description: EMdBamplifiers dot com **Contact us first for price negotiation and custom builds before purchasing.** Please reach out to me first to discuss pricing or to inquire about custom-built LDMOS transistor amplifiers ranging from 600w, 3000w, and others. I also offer repair services and can assemble an LDMOS amplifier using a board/pallet from another vendor if provided. For my own projects, I utilize custom-made boards/pallets. Please note that I do not construct 12v amplifiers; only 50v amplifiers are available. The "not working" or "for parts" designation is due to eBay's policies, which unfortunately benefit part scavengers and scammers. Additionally, the high price is to compensate for the high fees associated with selling on this platform. **Important Information** Kindly review the entire description before making a purchase. By shopping from this store, you agree to the following terms: **Product Details:** - Proudly crafted in the USA using local and imported components, featuring original Ampleon transistors. - Specifications: 1500 watts, with 600w on 6m. Equipped with 2x BLF188XR transistors. - Front panel includes PA voltage and amperage indicators, along with a manual band switch for the Low Pass Filter. - Features an internal relay that reduces heat by turning off bias during standby mode. - Accepts 25 to 80 watts RMS input (varies by band; final specs provided post-testing). - RCA connector PTT input allows for activation using your preferred ham transceiver. **Power Requirements:** - Requires an external 50-volt, 50-ampere power supply, and 12 volts for bias, relays, and fans. - Not suitable for mobile use or as a CB (11m) 12-volt amplifier. Feel free to contact me for further inquiries or custom requests. 1500w average typical @ 14.2MHz CW/PEP Max 600w average typical @ 52MHz CW/PEP Max Max current draw: 45 amperes @ 50 volts 2 amperes @ 12 volts **AM Mode Usage Explanation:** When using AM mode, it's crucial to follow these guidelines for optimal performance: - The AM carrier should always be four times less than the total output power. For example, in an amplifier with a total power of 1500w PEP in AM mode, the carrier (or dead key, unmodulated) should be set at 375w. With 100% modulation, you can achieve the full 1500w PEP output. Keep in mind that in AM mode, the voltage produced by the transistors at full modulation will be double compared to CW mode, so avoid overdriving the amplifier. - Measurements for AM and SSB modes should be in PEP (Peak Envelope Power), and it's recommended to use a wattmeter with Average and PEP readings for accurate measurement. Please note that not all bands or modes will deliver the advertised wattage due to various factors. **More Product Details:** - This sale includes the amplifier with an external power supply(not in the pictures). Other items shown in the pictures are not included. - Approximate case measurements for the amplifier are 14 1/4" x 13 1/2" x 5 1/4", excluding front switches, cables, top fan filters, or back connectors. - All measurements are conducted using Bird watt meters, with RMS readings measured using a dead key non-modulated CW signal. Harmonics are measured using a Bird Signal Hawk spectrum analyzer, and other measurements are done using a Fluke scope meter/oscilloscope. Wattage measurements are performed off the air using a CDI 50 ohms 10kw terminating load (dummy load). - Adequate ventilation, a cool room temperature, a 50-volt power supply with 50 amperes, and a 12-volt power supply are required for proper amplifier operation. Failure to adhere to these requirements may result in amplifier malfunction or damage. - This amplifier is a result of extensive research, development, and investment. Updates to the design may occur to enhance its performance. - Please note a handling time of 60 business days. If this timeframe is not suitable, kindly refrain from purchasing. Amplifiers are built upon order, and while it may not take the full 60 days, ensuring quality and safety is a priority. --------------------------------------------- **Important Notices and Warranty Information:** **Ampleon BLF188XR Transistor Caution:** While the Ampleon BLF188XR transistor is rugged, it is not impervious to failure. Avoid exceeding 45 amperes (typical for this amplifier with 2 BLF188XR transistors) to prevent damage. Overdriving the amplifier can lead to undesirable outcomes, so please refrain from doing so. Remember, never engage in actions that could harm the amplifier. **Usage Guidelines:** - Utilize a Low Pass Filter on Ham radio bands. - Ensure proper ventilation and maintain a cool room temperature. - Adhere to FCC rules and regulations. **Warranty and Repairs:** - A 30-day workmanship warranty is provided, excluding transistors. - Transistors are not covered under any circumstances. - Repairs are available for a nominal fee; contact details are provided below. - No other warranties, replacements, or returns are offered. **Shipping and Handling:** - The seller uses eBay shipping labels for controlled shipping processes. - Insurance for additional protection is recommended; inquire for details. - Local pickup is subject to the seller's terms and availability; contact in advance. **Product Details and Variability:** - All pictures serve as references; actual product may vary. - The listing guarantees the inclusion of 2 BLF188XR transistors or their original equivalents. - Electronic parts are sourced from authorized distributors, ensuring quality and authenticity. - The power output may vary based on radio, antenna, frequency, coaxial cable, SWR, and other factors. - Ongoing improvements may result in slight variations from the displayed pictures; refer to the latest updates provided by the seller. 3/16/24 For further information or assistance, please contact the seller directly.
