Hey guys. Built this a while ago, and got a bit cranky with it, so left it alone. Time to try again though.
Boost works. (Yay). LED for overdrive channel works. So power at the switch then. :S When volume maxed, hear a little bit of noise. Nothing really musical though.
Op amp voltages...
1 - 4.53
2 - 4.54
3 - 4.53
4 - 0.0
5 - 4.53
6 - 4.65
7 - 4.53
8 - 9.07
Top - 9.08
Mid - 4.16
Bottom - 3.77
Top - 9.07
Mid - 4.14
Bottom - 3.74
Continutity eyelet 4 to bottom leg R1 0.4 ohm
Continutity eyelet 8 to top leg R14 0.4 ohm
With a signal tester:
Center pin of Q1 = Clean
Bottom pin of Q1 = Clean
Pin 5 of IC1 = Nothing
Pin 7 of IC1 = Nothing
Pin 3 of IC1 = Nothing
Pin 1 of IC1 = Signal but crackly and not very loud
Center pin of Q2 = Signal but crackly and not very loud
Bottom of Q2 = Signal but crackly and not very loud
The outside leg of the level pot and the middle give the same signal. Weak, crackly
Tried the other op-amp that came with the kit, and was able to pick up AM Radio
(a local station. 2BS Bathurst, if you must know.
), but still signal is weak and crackly
Please help me. I like the radio, but not through my amp. :S
btw: Will try to get a couple of shots of the board as soon as i can.
