Just built a second one of these kits, 1st worked fine.
This one is working but with no output from the speaker; output from the line-out is good. High frequency square wave on both speaker lines (ref zero volt line).
As the speaker lines go directly to the chip ??? Is a filter somewhere not working.
Any one got any ideas?
Cheers Charles
Most likely a defective chip.
Please return it for inspection/exchange to:
Velleman Kit Tech Dept.
Legen Heirweg 33
9890 Gavere
Belgium
Many thanks for the offer to check/replace the chip. As the line-out is working I have stiched it to the output stage of a “crazy Music generator” (which is rubbish) and so am getting an audio output. This is all to get a final year student’s “musical tapestry” working for the end of the month - the cobble-up will do and time is running out.
