Radio receiver R-390A/URR manufactured by AMELCO under Collins Radio's patent, s/n 637. Here is an historic piece of equipment that has become rare to find in good working conditions. The R-390A/URR provides reception of continuous-wave (CW), modulated-continuous-wave (MCW), frequency-shift keyed (FSK), and single-sideband (SSB) signals. A double sideband signal, either AM or phase-modulated (PM), occupying up to a total of 12 kHz of spectrum for voice transmission may also be received Radio Receiver R-390A/URR is a super heterodyne type with multiple frequency conversion covering a frequency range of 0.5 to 32 MHz. Double conversion is used when operating from 8.0 to 32 MHz, and triple conversion when operating from 0.5 to 8.0 MHz. Linear tuning provides constant frequency spread throughout the entire range. Tuning is accomplished by positioning powdered-iron cores in the RF and IF coils, at a rate controlled by a mechanical arrangement of gears, shafts, and cams. The operating frequency is read from a counter-type indicator. A built-in crystal-controlled oscillator provides frequency calibration. The output of the LOCAL AUDIO provides either 500 mW power to a 600 ohm load or 1 mW for a headset, while the output of the LINE AUDIO provides a 10 mW output Into a 600 ohm balanced line. A BREAK-IN relay is also provided to disconnect the antenna when an associated transmitter is keyed. List of tubes: 6DC6, 6AK5W, 6AK5W, 6C4, 6C4, 6C4, 6BA6W,6BA6W, 6BA6W, 6BA6W, 6BA6W, 6BA6W, 6AK6, 6AK6, 6AK6, 5814A, 5814A, 5814A, 5814A, 5814A, 5814A, 5814A, 26Z5W, 26Z5W, 3TF7, 0A2.                                         Original characteristics : Frequency range 0.5 to 32 MHz Types of signals received CW, MCW, FSK, SSB, and AM Frequency indication Read from digital Indicator Method of calibration Built-In crystal-controlled oscillator Calibration accuracy Less Than 300 Hz Calibration points Every 100 kHz Sensitivity (signal plus noise to noise ratio) AM sensitivity CW sensitivity 5 μV at 10dB rise 1 μV at 10dB rise       Modifications : 1-    220V mains filter (Schaffner) has been added 2-    On state surge current limiter (Keystone Thermometrics ICL) 3-    SO-239 antenna socket 4-    Audio transformer to use a 4 or 8 Ohm speaker (instead of the regular 600 Ohm speaker) 5-    All tubes have been replaced by N.O.S.

Description: DANTEK PoE-24V Injector inserts current into the unused wires in a standard network cable(pin: 4, 5, 7, 8) to allow the cable between PoE-24V Injector and PoE-24VS Splitter to transfer power and network signals simultaneously. - When positioning network devices, system designers always have to consider the location of power outlets. In some cases, this will restrict the optimum placement of devices or incur additional cost in installing new outlets. Dantek's PoE-24V/PoE-24VS offer the solution of these problems. - Using the Dantek POE-24V/POE-24VS adapters, you can power most DC network devices (hubs, Wireless access points, cameras etc) over the same Cat 5/5e cable used to connect the device to the network.       2. Features • Provides 24V low-voltage DC power over existing Category 5 cabling to a device with an Ethernet port • Distance up to 100 meters • Protects devices from possible damages due to power-surges • Three different output voltage options (5V/2A, 9V/1.2A, 12V/1A) to fit various devices • Work with EIA568, category 6, 5-pair cable for 10Base-T or 100Base-TX, Ethernet / Fast Ethernet network 3.

Applications Dantek PoE Save Your Power Infrastructure Cost PoE allows power to be supplied to end devices, such as Wireless Access Points or VoIP Phones, directly through the existing LAN cables. By supplying the power end-span, you can centralize power distribution and backup without the need to increase infrastructure. Please note: 1.  PoE-24V/PoE-24VS does not comply with IEEE802.3af, Don’t connect any of it to an IEEE802.3af devices. For PoE-24V, it will inject power all the time when it is connected with a AC/DC 24V adaptor.  It means that (pin: 4, 5, 7, 8) inject power all the time, so when you connect it into network, please make sure the safety of body and connected equipment. POE-24VS is not an IEEE802.3af complied device, PoE-24VS will not detect and reply the signal from 802.3af injector. As a result, the Power LED will never turns on if you connect to an IEEE802.3af injector and never power the remote device as well. Gigabit Ethernet is not allowed to use PoE-24V/PoE-24VS products since pair 4,5 and pair 7,8 are all being used. Only 10/100M TX can apply with our PoE-24V/PoE-24VS. For safety reason, PoE-24V/PoE-24VS will only support device with power consumption below 12watts. Please make sure the remote Ethernet device is under the range of 12V/1A, 9V/1.2A, 5V/2A. Please by using PoE-24V/PoE-24VS together on both sides of cable all the time. Créé par L'outil de m

HIGH PERFORMANCE AUDIO - Discrete Class A Amplifier A Class A amplifier conducts signal over the entire range of the input signal cycle. The output transistors are biased to operate in their most linear range, and there is no crossover distortion caused by switching the signal between two push-pull devices. The HA-1's power amplification circuit for the headphones is Class A built with discrete transistors. The discrete design allows us to hand-pick and match the best parts to build the HA-1. - Toroidal Power Supply A toroidal power transformer offers superior power efficiency and much lower exterior magnetic fields over traditional laminated steel core transformers. The HA-1's toroidal linear power supply provides a very clean and robust power source to the audio components. - Fully Balanced Design The internal analog audio signal path of the HA-1 is fully balanced. For digital audio, the signal runs in balanced mode all the way from the DAC to the output jacks. Balanced analog input is kept intact, and single-ended input is converted to balanced at the input buffer. All single-ended outputs are derived from the balanced signal as well. The balanced design provides better common-mode noise rejection and improves signal quality. The balanced headphone output provides twice the voltage and four times the power of the single-ended output, enabling the HA-1 to drive the most power hungry headphones. It also provides better channel seperation by eliminating the common ground return path. - ESS Sabre32 Reference DAC The DAC is one of the most important components for digital audio playback. The SABRE32 Reference ES9018 from ESS Technology is the world’s best performing 32-bit audio DAC solution targeted for high-end consumer applications and professional studio equipment. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented DNR (Dynamic Range) of up to 135dB and THD+N (Total Harmonic Distortion plus Noise) of -120dB, the industry’s highest performance level that will satisfy even the most demanding audio enthusiast. To learn more about the technologies behind the exceptional performance of the SABRE DAC, please read the SABRE Technical White Paper. OPPO HA-1 4.3" information display - Clean Signal Path The HA-1 uses an analog potentiometer (the familar volume knob) to control the volume. By avoiding re-digitizing the audio signal for volume adjustment, the HA-1 provides a clean signal path for the audio. At the same time, the convenience of modern digital volume control is not lost - a remote-controlled motor turns the volume knob and a 10-bit analog-to-digital converter samples the signal to display a numeric dB level. - Made for iPod®, iPhone® and iPad® The HA-1 passes Apple's "MFi" certification and is compatibile with the latest iPod, iPhone and iPad to be used as the digital audio output accessory of these devices. By tapping directly into the digital audio signal of these devices and converting the audio to analog using the high performance SABRE32 Reference DAC, music from your favorite portable device will sound its best. - Wireless Audio via Bluetooth The HA-1 supports Bluetooth Advanced Audio Distribution Profile (A2DP) with both the standard and aptX® high quality codec. Simply pair your phone with the HA-1 and set music free
