Questions? Call us at 800-426-2344. How To Recycle Your Circuit Boards. We make it fast and easy to recycle your company’s circuit boards – in fact, you’ll be paid upon completion of processing, usually within 25 to 35 business days from the day we receive your circuit board scrap. A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.

Over recent times, the value of gold has increased significantly, making printed circuit board recycling even more viable than ever. If making money from items you would have just thrown away isn’t reason enough, the Waste Electrical and Electronic Equipment (WEEE) Directive came into force in 2003. In the mid 1980s QUAD made 405-2 amplifier PCBs for a famous British loudspeaker manufacturer who were going to produce a large active dipole loudspeaker which did not require the current limit ~ It is likely that QUAD found it easier to supply the early 405–2 PCBs from the production batches before fitting the SOA limiting ~ It is also likely that the SOA network was made on thick film ...

The famous $5 preamp - everything you need to know

The famous $5 preamp - everything you need to know

The least expensive hand-held unit is several hundred dollars, but worth every penny. It's easy to move across a board, checking all the caps and noting anything suspicious. Almost all capacitors can be checked in-circuit with sufficient accuracy to determine if they're the cause of a problem. If all the resistors are all of the same ohmic value, that is: R1 = R2 = R3 = R4 then the circuit will become a Unity Gain Differential Amplifier and the voltage gain of the amplifier will be exactly one or unity. Then the output expression would simply be Vout = V 2 – V 1.. Also note that if input V1 is higher than input V2 the output voltage sum will be negative, and if V2 is higher than ...

QUAD 405-2 Amplifier Modification and Information

QUAD 405-2 Amplifier Modification and Information

The circuit symbol shown above for an enhancement MOS transistor uses a broken channel line to signify a normally open non-conducting channel. For the n-channel enhancement MOS transistor a drain current will only flow when a gate voltage ( V GS ) is applied to the gate terminal greater than the threshold voltage ( V TH ) level in which conductance takes place making it a transconductance device.  · Recycling e-waste enables us to recover various valuable metals and other materials from electronics, saving natural resources (energy), reducing pollution, conserving landfill space, and creating jobs. According to the EPA, recycling one million laptops can save the energy equivalent of electricity that can run 3,657 U.S. s for a year.
