Hi,
I have been experimenting with a pain relief unit working on producing similar results to a TENs unit. One of the drawbacks with a TENs unitis that it produces a more or less continuous output.
The signal for my unit is provided from a pre-recorded wave fed into a battery power amp. The output from the amp then goes through a reversed audio output transformer[RS 273-1380] to two TENs pads. The amp is protected by a 4 ohm resistor between the amp and the transformer.
Unfortunately the transformer soon saturates. Is there a simple way to prevent this from happening? A typical load is assumed to be about 500ohms.
