Description

Assembly Required

Ref: Silicon Chip March 1994

This 50 watt unit uses a single chip module and provides 50 watts RMS into 8 ohms with very low distortion and extreme quietness.
- PC Board size only 84 x 58mm.

Kit is supplied in short form version.
PC Board and electronic components only supplied.
Heatsink Optional

Power supply not included.
Power Requirements:

+/-35VDC rails @ 80VA per module
MT2114 25 + 25V 160VA toroid x 1
ZR1314 Bridge rectifier x 1
RE6241 2,200/50V electro caps x 2

Note: The LM3876 used in this design has been changed to severely limit its power output into 4 Ohm loads. If you want to use a 4 Ohm load, the solution is to use the LM3886 which can deliver over 60W. However the supply rails should be reduced to +/- 28V, as recommended in the article for the LM3876 when using 4 Ohms loads.
