some amplifiers

[vicelord]

Hello

i have 3amplifiers
the first is a blapunkt a-5800~ i changed the tranzistors in it and now it is working but i dont know his power

the second its a Kenwood ka 80b- i dont know why but doesn't works and i was wandering if i could replace the power amplifier in it and keep the chais radiator and power suply

and the last is a technics-su600 i have the same problems as with tre kenwood

sorry for mai bad english
i hope i will recive some help

Thank's Bogdan
