[trancy]

what should i change on zen1 (original one) if i want to drive 4 ohm speakers...yes i know...paralel amp, but i dont want that...

thanks

i`m no pro, just trying to help.


you could try lowering the rail voltage or increasing the tran`s current handling.


with a lower load, i guess the only problem you will face would be a lack of current.

yaeh, but simplier for me will be like that: change Rx from xx to yy, and so on....

There should be a .66 volt across a .33 ohm R1. This sets the bias at 2 amps.
Change the value of R1 to a lower value. A .22 ohm will give 3 amp bias. Two .33 ohm in parrallel .165 ohm will be 4 amp bias.
This will make the amp run hotter. Have plenty on heatsinking.
