While making a pimeta amp, I'm stuck on measuring the voltages now. The LED burns and nothing gets hot, so I started measuring the chips' pins.
The CMOY guide sais as follows:
The voltages I got, are not exactly identical, I put them in the schematic at the pin they were measured (I used the Pot Ground as Virtual Ground):
Values in Volt, btw. Also, I get a reading where I guess I shouldn't ? (The circled one)
Very strange, because I haven't soldered anything at the buffer pads yet (not even sockets) because I've got the SO-8 version of the chip and decided not to solder it down until the rest was finished. Any ideas on what this might be ?

| you should see a positive DC voltage at one cap and a negative voltage at the other cap, and their magnitudes should be nearly identical. For example, if you're using a 9V battery that's been depleted to 8V, you should see almost exactly +4VDC and -4VDC. If you're off by more than a tenth of a volt or so, you did something wrong in hooking the circuit up. |
