While I have built electronic devices from kits several times I want to keep this simple. After reading almost all the post in this froum I think I understand things.
Please let me know if the following makes sense or I am missing something. (I will be using this with the teases which have an element of torture/punishment/pain so I want to make certain it has enough power to accomplish that).
- will be getting the input from one of the teases here, it will run on my PC which has both BT as well as a sound card with a line out jack.
- I'm looking at this amp on Amazon. It comes with a 36VDC power supply but since it is rated for max power using a 48VDC power supply I might try that one. https://fosiaudio.com/products/bt20a-pr ... -amplifier
- I would use a pair of transformers like these: https://www.osdaudio.com/sp70t-20w-8-oh ... depot.html
- Not sure about the need for power resistors both in series and parallel. I have read mixed reviews. I have resistors I can try and I believe this amp has protection circuits which would work with the load the transformers would supply due the resistance/impedance of the primary winding.
- And if I read everything correctly the transformers would provide: isolation, voltage step up, and would be wired backwards or opposite of what they are generally wound, using the 4 or 8 ohms on the amplifier side and the highest wattage on the secondary or load side.
