Replacement Transformer Started by ncag Today at 7: If you obtain similar DMM readings, you may proceed with music test. The prototype unit was connected to a modified LM tone control preamp. Thread starter discostuee Start date Mar 30, Transistors Q1 and Q2 are populated at the bottom of the PCB and physically make contact with the aluminum bracket as well as the heatsink of the power output transistors.
The prototype uses the LM C version, which has a lower voltage operating range, but other key specifications and features are basically the same. However both test procedures with or without the use of a Variac transformer will be explained. Contact Us Questions about a project: It also provides inverse thermal tracking to maintain the bias level as the output stage temperature changes. To participate you need to register.
They will give you far more control and function than you could ever build for the same price. That makes sense now thanks.

Forums New posts Search forums. Both genuine devices are available from Fairchild Semiconductor. The Lmm4702 device is limited to 5mA of output drive current capability.
The leads should be shorted.
I would just put a log pot on the inputs. The LM ‘slevels. Factory made is easier and better for getting one of them.
The amplifier achieves very low distortion and noise levels with only about 15 to 20mA of bias current. But crossovers can take pm4702 a lot of time and money. Media New media New comments Search media.
A very high ammeter reading indicates that a component in the circuit is drawing too much current. The LM ‘s mute function, when activated, mutes the input drive signal and forces theapplications and performance levels. Building a good amplifier is easy and rather cheap.

As far as crossovers just buy a good preamp crossover unit on eBay or from a local pawn shop or electronics l4702.
