Up for your bidding pleasure is this nice, clean COLLINS 516F-2 POWER SUPPLY FOR KWM-2 transceivers and S series 32s-1/3 transmitters. I changed all but one of the electrolytic capacitors. I didn’t replace the.05uf at 1000v on the HV output as they hardly ever go bad. It comes just as you see it with a 5u4 HV and 5R4 LV tube.  All voltages check out and It worked fine the last time it was used on Nov 2020 running my KWM-2. There is a small chip out of the edge of one of the 5R4 tube socket but doesn’t effect it’s operation and the prior owner put black tape on the end of the 11 pin power cable at the strain relief. Please look closely at the photos, I welcome any questions. Do to the fragile nature of vintage electronics over 50+ years old this power supply is being sold Condition is "For parts or not working", No returns, No case or speaker is included. It will be packed with care, shipped with USPS Parcel select. Happy bidding and be sure to check my other cool HAM radio auctions.

1. Introduction   This FM stereo digital radio circuit board module has built-in DSP digital noise processing. When there is no signal, it will automatically mute and get rid of the noise of the traditional FM radio.   2.   Parameter   NO. Parameter Value 1 Output power 500mW (drive earphone), 3Wx2 (drive horn) 2 Frequency range 50Hz-18KHz  3 Receiving frequency range 87.0MHz-108.0MHz 4 Equivalent noise Greater than 30dB 5 Power supply voltage 3.0V-5.0V 6 Power supply current 1000mA at maximum volume, 60mA at minimum volume (for reference only) 7 Sound track Stereo       3. Using attention:   1>. The power supply voltage is strictly prohibited to exceed the power supply voltage range of this module. 2>. Do not touch the back part of the module when working, so as not to affect the normal work of this module or cause the short-circuit burn module.   4. Feature   1>. Advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation (PLL) make the sound quality more realistic, more stable performance, and long working frequency without deviation. 2>. LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference. 3>. 30 digital volume adjustment, with buttons, easy to operate. 4>. Automatically storage data before power off. 5>. Automatic switch of speaker/headphone output. 6>. Quartz crystal steady frequency, temperature change reception frequency, no longer drift. 7>. It uses professional audio DSP to analyze and process the audio signal, and automatically mute when there is no signal or weak signal. 8>. It uses incremental digital rotary encoder to adjust the volume and frequency, using the feel is good, positioning accuracy, stable and durable, 360 ° rotating without blind Angle. 9> Support serial communication control, available computer or MCU and other devices with serial ports to control all functions of the module.   5. Instruction   1>. Power supply Module corresponding port (marked on PCB board). “-” and “+” are the anode and cathode of the power (battery). The power supply is recommended for battery or other stabilized power supply.You cannot use a power supply without filter (such as mobile phone charger, mobile power supply, and other switching power supply), otherwise the interference caused by power supply will affect the normal work of this module. The normal working voltage of this module is 3.0-5.0V, not exceeding this range. At the maximum volume of the module, the maximum power supply current is around 1A, which requires the battery to output enough current. 2>. Antenna The FM_ANT port is used to connect the FM antenna. To better receive the FM signal, it is recommended to extend the antenna with a length of 75cm. 3>. Headset/speaker output This module is with 3WX2 channel audio amplifier. If the horn is needed, access the speaker port. It is recommended to use 4 Ω / 3 w speakers.If the headset is inserted, the audio will automatically switch to the headphone channel, and the speaker channel will be closed automatically. 4>. Volume Turn the VOL encoder to adjust the volume, while the LCD screen displays the volume series. 5>. Frequency regulation Turn the FRE encoder to adjust the reception frequency, while the LCD screen displays the current frequency, and press the encoder handle to the mute/non-mute switch. 6>. Mute Press the VOL knob to switch the mute/non-mute button down. 7>. AMCAP switch Long press the FRE knob to switch on or off the AMCAP, the LCD display subtitle ON means to turn on the AMCAP, and OFF means to turn off the AMCAP. 8>. AMCAP threshold adjustment(when the AMCAP switch on) Short press the FRE knob to AMCAP threshold adjustment interface, you can adjust the movement threshold of the AMCAP according to the specific usage situation. The adjustment range is 0-20. The higher the value is, the higher the threshold is, the easier the weak signal is to be silent. Vice versa. 9>. Serial port (without serial port control) The module reserved TTL level serial port control interface. TTL serial port and this module communication need to connect the module's UART_RX, UART_TX and GND (the corresponding position of PCB is marked). You can use the external MCU or the computer serial port to send the command control module related functions. Note: because the computer serial port is not TTL level, connect the computer communication, it is necessary to connect the RS323 level to TTL power leveling device or the USB TTL level serial port module to communicate with this module. This operation requires professionals. 10>. User Settings This module can set the backlight state according to the user's specific usage. When the power is off, press the FRE button to turn on, and the B0 indicates that the backlight is always bright. B0 indicates that the backlight is closed for 20 seconds, and the setting is effective after the restart. Change the Settings state to repeat this step to switch. The backlight has no operation for 20 seconds. 11>. Stereo /mono switch terminal. Stereo/mono terminals are used to set the FM receiving mode of the module. This terminal is suspended for Stereo reception mode, and it is a single channel receiving mode.   6.
