simple amplifier

[sakis]

hello lovely people of the forum !!!! my target is a simple amplifier that is cheap madeof simple materials ( also probably medium or even poor sound quality ) for shure low costed but mostly simple to make .....one thing cannot change is power requirments that should be 150 w SOA with a peak of 200w

i tryied everything ....john fishers "simple amp " (tip 142 147) updated with mj 11016-15 ( mever managed ) to make it balance always ocilating and a lot of smoke

then 82089 -1 electors amplifier ( originally bdx67-68 vcc +-44v ) converted with a pair of mj 11016-15 vcc 60v with alot of problems mostly idle current and others

then again smart kit 1077 originaly bdv 66 67 vcc +-40 v with the same mods increase of vcc and biger out puts but no working stable

all these are available in the net but nothing of it could perform stable soa 150w ......

in the past ive meet one amp made of grundig ( ????? ) with 2 pairs of bd 249-250 capable of about 160w/channel in a board no biger than 10 x10 cm !!!!!! had to repair it and make some tests about power mostly and at the time had no expirience to tell if sound was good but in my ears sounded warm ....thats 20 years ago ....never seen it again ...

any sugestions ???? THANX....
