PCB for STK4048XI...

[Tomom]

I have PCB for STK4048XI; it will suit other 18 pin STK modules, with eventual ommiting some components, according to SANYO schematic.One PCB has provision for TWo amplifiers positioned in-line, so they can both be conveniently positioned on one heat sink. On board is also BRIDGING circuit, so one PCB can be used for two channels in stereo, or one in bridged configuration.

Also I have Power Supply PCB. It is serious design that will get as much rubish as possible off your supply line. It has 2 x 10,000 uF per rail, so you can start with one cap, then add another if needed ( you may often find that it is). Each rail is taken from its' own bridge. A smaller value of 100uF in parallel with 100nF filters any RF collected on the line. Finaly, RC network gets rid of residiual capacitor inductance. Obviously, PS PCB can be used for other projects, not just STK...

STK PCB ( 82 x 205mm) ...AU$22
PS PCB (90 x 185) ..........AU$22
2 x STK4048XI ("K") ........AU$52
