is there a way to step up the output, i would like to get it to around 250 watts
no way!!!

you cant get any more power on that IC

its characteristic is the same as LM2005T

20 watts bridge connection

for a 250 watts, you can only attain this power by using higher supply voltage such as +/-35 volts

Oh I think we can squeeze 250 watts out of that circuit.... say IHF ratings at 1kc. for 1 microsecond.

The TDA2005 isn't a hi-fi amp, it is a car radio amp. Its distortion is typically 0.3% (1% max) as a 2-channel stereo amp, up to 6W RMS per channel into 2 ohm speakers and a 14.4V supply.
If you want very low distortion then use a hi-fi amp IC. They need a supply voltage much higher than a car battery and drive 8 ohm speakers.

High End Audio Amplifier

Is there anyone interest with creating new Hi-End Audio Amplifier thread?
I've initiate it, but I've no access to do it.

I'll help to start it with my 7th version K32 that been fixed in dec2005.
And also analyze old halcro schematic.
