perdon por el idioma, no hablo ingles
el amplificador es de 3600wrms 1800wrms por canal trabaja con 70v+- y 150v+- debe utilisar transistores de potencia que soporten mas de 300vce

1 100 ohm base resistances to mje 15032 33 should be 1 WATT EACH

3 51 KILOHM is correct value instead of 5,1 kiloohm between pin no 6 of ic and ground

hi diyers
greetings maxter tested in ab class using 8 pairs crisp sound very clear on switching on with
speaker connected you will hear motorboating sound dc voltage present but if connected with delay on or dc protector delay on amplifier dc problem is solved ampifier works excellent WILL BE ATTACHING
STEP DRIVER HOPE IT WORKS WELL will post step driver and pcb if tests are good
thanking you

05-15-2011, 08:49 AM
Motor boating sound due to 15v supply delay, use zener 16v 3amp or 5amp and if main dc less than 50 v ,use 2k2 /5watt both side
(sorry my English is poor)

michelle
05-15-2011, 01:58 PM
hi mkubawat
greetings this problem is solved using delay on relay as the diyers who have built it have used relay on driving pcb other than this amp performance is good

when i drive 1000w sub (p audio c18-1000) with this amp after 1 hour speaker blown why?

Hello master on 7 pairs with signal,clip,power,h rail indacator

7 pairs still good response but driver side is very stressful
unbalance trigger on step drive +side trigger faster than -side ( i hope i can fix this)
next test applying triple ef on output stage to solve the problem of driver stage

master 3k6

i just found and fix the unbalance voltage out of the step by following the original values of master 3k6 change some value of resistors and add 1 5k variable
now voltage out +/- on step are now balance
step driver have trim pot to adjust +high rail only

tested in full range and sub its stunning response

mkubawat
06-28-2011, 04:54 PM
Good job irvynejay
Please tell us what changes you made ​​in circuit , How much HV & LV was kept during observation & why connect LED with both diode

irvynejay
06-28-2011, 11:08 PM
62/122 -/+ LED are indicators for high rail is triggering its on original step of master 3k6
changes was made, i replace 2 47k to 4.7k and 2.7k to 270k from the input of the step after 1n4007 and added 5k trimmer series with 2.2k on +side input of step
Why did i change it? because once the the step triggers both rails is not balance so i try to follow the original set up on input of the step to adjust +side of the HV
file attach for reference
**
i far as i notice upon surfing the net looking for answer the driver board is copied on crest audio and the step driver is from master DPU 3k6

what particular crest model this main board and output board copied?

irvynejay
07-02-2011, 12:18 AM
engel sorry but i was wrong upon reviewing the schematic its not crest it's only DPU3k6

To achieve the full power of the amp voltage should be 70/152 -/+ and the power output trannies should be MJL4281a or higher
