Natapos din sa wakas
Bill of MaterialsResistors (metal film type preferred)
1 x 470 ohms
1 x 100 ohms
Capacitors (metal film non-polar, poly or mylar type prefered)
2 x 0.47uF
4 x 1uF
1 x 2.2uF
1 x 47uF (Tantalum type)
Wires - just in case hindi magkasya yung cap sa PCB, especially for the 2.2uF capacitor.
ICs (optional)
Burr Brown OPA2134PA
PCB bread board
1 x 8 pin socket (4 per side)
1 x 8 pin socket (8 inline)
InstructionsReplace R5 to 470ohms
Replace R36 to 100ohms
Replace C1 and C2 to .47uF
Replace C4, C6, C17 and C14 to 1uF
Replace C13 to 2.2uF or (1.47uf, 1 x 1uF and .47uF in parralel, kung ayaw nyo na ma-bass)
Replace C3 to 47uF (tantalum)
Optional : Op Amp upgrade ala Monte Allum
2 x 4 pins to 1 x 8 pin converter.
Remove IC2 (NJM4558) and replace with 8 inline IC socket. Recommend ko na gumamit ng desoldering braid para mas madaling tanggalin yung IC and hindi masira.
Cut a square 10 x 10 hole sa pcb bread board. Gamit kong paa ng adaptor yung mga tira tirang wire galing sa resistor. Eto yung layout sa PCB para dun sa adaptor.
Eto yung gawa ko. Ampanget pero pwede na
Chip installed, mas mabright at mas mavolume yung TI4558 at JRC4558 op amps pero mas malinaw naman yung tunog ng nung Burr Brown chip.
Pinalitan ko din lahat ng resistors at capacitors, badtrip lang dahil maliliit na resistors ang ginamit nila sa CS3 pero ang laking improvement naman sa pagreduce ng noise sa pedal na ito.
Final ProductSound Clip!!0:00-0:07 - guitar and amp
0:07-1:17 - CS 3 engaged all knobs set to 1 o' clock (compressor mode).
1:17-2:23 - CS 3 engaged, attack at min level, sustain at max level (limiter mode)
