Hi brian

Sorry for the delay on the reply. I've been a bit busy.

The modulation sounded fine with the 4n7 capacitor in but sounded slightly better in my case with the 1n8 capacitor. Overall the modulation is 100% better.

Cheers

Hi Brian
Thanks for the information regarding the echo board. I have replaced R1 with the 10K you suggested and replaced C4 with a smaller value of 1800pf. Tried a number of different values of capacitor and the 1800pf was the best in this case.
Thanks for your help.
