I'm sure you guys are sick of me prattling on about this but here's what i did.
I plugged a 3.5mm plug into my cell phone and measured the output resistance, it was 68Ω, i then measured the output of the syntom and it was 63KΩ sooooo on the advice of Audioguru i whipped R28 out of the circuit and replaced it with a 1u Electrolytic, on scoping the output i found the output with it's attendant signal slowely sank to ground on power up, then i had my AC coupled signal bouncing around the 0V rail out, i added the 10K resistor after the 1u cap to ground and then on power up i had my signal immediately sit at ground, no more floating.
Then i got brave and thought ok here goes, i plugged the output of the syntom into the amp, and switched the amp on, i then held my breath and hit the power to the syntom, i nearly fell out of my chair when i heard a slow falling pitch, on tapping the piezo transducer i now get a variety of falling pitch sounds....i am absolutely over the moon!!!!!!!!!
thankyou all so much for your help, i am delighted!!!!
Now i just gotta box the beast up and build my disco light modulator and then i am going to get a good book or find a good site online and learn the art of analogue electronics, a thoroughly fascinating and intrigueing subject!
thankyou again.
Neil.
