HC1011 BASH Klipsch Replacement ProMedia 5.1 Ultra RSW10 Harman Kardon IL50 IL60

Description: This new circuit board replaces the BASH HC1011 board used in Klipsch's ProMedia 5.1 and 4.1 computer speaker systems, their RSW10 subwoofer, and Harman Kardon's IL50 & IL60 speaker with active sub. This new, 2023 board performs the same as the old BASH HC1011 boards, without being brittle. I use these on every ProMedia 5.1 amplifier that I sell.Do I need this circuit board? If your Klipsch ProMedia system has distortion in the satellite and/ or subwoofer channels, and your input cables, speakers and sound card are good, then it is likely that your original ceramic BASH HC1011 circuit board is failing. I have replaced hundreds of these over 18 years, but until 2020, only ceramic replacements were available. Ceramic BASH boards, whether new or refurbished, have the same problems of brittle connections. The problem is so common that from 2012 to 2020 I installed 15-pin sockets in the ProMedia 5.1 amplifiers I worked on, so that replacing the BASH HC1011 boards in the future would be easier for an owner. The brittle connections in the originals are sometimes limited to just one that I could resolder (or replace the IC and remove the epoxy); other boards can have more breaks than I had room to add jumpers. Refurbishing never felt like a permanent solution. A knowledgeable engineer made this improved design possible. This replaces the common BASH HC1011, and the less common HC1010 and HC1012 boards. The ProMedia 4.1 uses one BASH board. The ProMedia 5.1 uses two boards: one for the satellite channels, and the other for the subwoofer channel.Tips for Replacement: Note: the board must be mounted facing the correct direction, or it will be damaged. The flat, non-component side for the new board corresponds with the flat, non-component side of the original boards. See the photo examples of the original HC1011 board mounted and how the replacement looks when mounted to the same amplifier. Be certain power has been disconnected for a minute before working, and that the board faces the same direction. If you have a good desoldering tool and above average soldering skill, you may remove your old 15-pin HC1011 board and install this. Probably the biggest challenge is desoldering all 15 pins from the original board to be able to remove it, but since that board will not be reused, you could gently bend the board back and forth along the pins to weaken the thin pins so that they snap and the board can remove, with the 15 pins still soldered in place. Then heat each pin separately, and use a tweezers or needlenose pliers to remove each pin, one at a time. Then use a suction bulb or solder wick to remove the solder. What if my original HC1011 board has a 15-pin socket? If you are a previous customer of mine and had your amplifier repaired by me between the summer of 2012 and before these new boards became available in the spring of 2020, your amplifier has 15-pin sockets. You can swap out the old board without any soldering needed. Ask me to include a complimentary small tube of E6000 adhesive for you, and it can be used to hold that board firmly inserted in its socket. The adhesive is offered as a courtesy to repeat customers. Just do not allow any adhesive onto the metal pins! Only apply a bead to the plastic socket and plastic header—not to any metal surfaces--after the board is fully inserted in the socket. I no longer uses sockets, since these new boards are expected to be a permanent solution, and soldering avoids risk of the board loosening from vibration.Discount Option: Check out my listing for this item in a category with lower fees!
