Maxter 3600

[mkubawat]

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)

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
thanking you

hi michelle
when i drive 1000w sub (p audio c18-1000) with this amp after 1 hour speaker blown why?
amp dc supply MV +/-50v & HV +/-110v. I think my step driver not work properly ( when speaker blown step voltage at output pcb was +/-52v to 65v )
thanks

hi mkubawat
greetings please post your stepdriver you have ringing problems if step driver have long interconnectionsit not work properly my other h class amp has over 75 volt output signal works superbly no speaker blown as yet why you dont have dc protector speakers are costly
thanking you

hi MicrosiM
please can you provide PCB layout of step driver

I dont have a PCB layout for that one.

I dont know if that circuit is what you are looking for.

relay delay on pcb

this is the orignal relay delay on used in maxter but any dc protector circuit is better you get delay on and dc protec

Dear michelle
I hav'nt find step driver transistorised version at h900 thread

maxter 3600 suitable step driver

hi diyers
anyone have perfect suitable step driver schematic & pcb layout for maxter 3600

 

[ravpreet420]

Plz sir post circuit schematic of step driver transistor version of h900

 

[michelle]

use mpsa42 mpsa92 2n3904 2n3906

 

[ravpreet420]

Thanx sir
if u have pcb layout of step driver plz send

 

[mkubawat]

waiting for pcb layout of step driver

step driver

hi
greetings step driver shown negative mv voltage out not working testing amp on ir2117 step this is a
tested design by apex audio but ir2117 ic is hard to get will post another step driver with easy to get parts will only post if step driver is working well and i am satisfied dont want diyers to waste time and money new step drive is by WORKHORSE from his 1.5 kw amp on diyaudio it should be ready in 2 or 3 days after testing if ok will post pcb
thanking you
