tancx for proiect av 800 ist very very good amplifier my is very very hapy

[retrosong]

i aem av 1200w/4 and 12 tranzistors irfp 240 -9240 per devices end power suply +- 115 vcc

Welcome to the forum.
What speakers will you use and is this picture your amplifier? Very nicely build.

from the picture i ve seen .......

this will not stand full power ...... if you push it to the limit is simply gona blow......

laying all these transistors on a heat sink and using just a piece of wire to supply them will have a serious drop of voltage from side to side ...... i f you supply them in the midle then you will have drop in the voltage on the sides ...... if you supply them with more than one cable will solve the voltage drop problem but to my opinion will also create ocilation ......

different voltage in every trs will create the thing that actually some transistors will not help others or not share load ecually..... curent resistor also will not help in this level of diference


let us now how it works i am curious

[retrosong]

this amplifir functionality with 2 years never nou problem in functionaliti in 2 yars la power suply +- 115 vcc this amplifier ist very good in functionality end very strong mr hohton is one genius scuzmi for bad englich anthoni(the saint) ist the best

schema pls

[retrosong]

the schematic ist av 800 you must eliminiert irf 610 and 9610 and R43 you must change Q23-irf 610 with bd 139 and atacly directly ist modification ist very very stabile function no goig in temperaturi irfp 9240 -240

[sakis]

sorry but with this you say +-115 volts this machine will produce more than 500w .... i think ( prsumed is AB) di you everoperated this amp at this power ????

this is av 1000 pcb
