I'm new here and to electronics as a whole so please excuse my probably stupid questions whilst I try and learn a bit. I recently decided to build a cmoy amp and so with my dodgy soldering skills I got going and managed to produce a wonderfully noisy amp with lots of clicking. It was round about this point I decided to rebuild it as my measurements were indicating my power supply had different readings on each side. This was something I checked with a 9v battery up front so I was a little disappointed.
Anyway I put together the power supply on a fresh start and my 9v was showing a +4.5 on one side and a -4.5 on the other so I was thrilled. I then plugged in my 24v power supply and again one side is 10.something and the other 13.something (one was negative I can't recall which though). These happen to be the same figures I was getting on my old amp. :-( Is the 24v just making my life difficult?
Also on my 2nd amp I added my led with a 10k resistor. This came on with the 9v battery (very softly) but not with the 24v power supply which confused me. The 24v power supply is a 24v 750mA supply. It was my original intention to just this power supply as I don't really need portability. I haven't tried with less resistance yet I suspect this has something to with it but I don't really understand why.
Anyway I'd appreciate any help/suggestions/explanations from anyone who understands this better than I do.
Thank you kindly.
