active xover + SoZ= less problems because no passive filters with DCR?

I did read the Zenlightenment,but i couldnt afford to run it!
,energy is currently 14c/kwhr and no sign of getting cheaper(theyd rather make money than invest in the countrys power grid),i keep my 1kw heater on 1/2 for only a few hours at nite in winter(light snow)yet our power bill is too much still!.....

student life!

hugely inefficient amplifiers maynot be so useful for me for this reason, unless i want heat + music at the same time!

I think that a SoZ might well be worth it, i got some 19" rack cases with finned heatsinks covering the ENTIRE Top of it! which is about 2x the area on my dodgy '350w' plate amp

I photocopied the ELektor article today,il scan it sometime :-)
but yes its just an input buffer fet,constant current source fet and output in class A uses a 6v voltage regulator for gate voltage

A dozen resistors,a dozen caps, BUZ72A and BS170 fets
Cheers!
