Hello, The PWM part of the DXR15 device that has water in it, which gives the DC voltages, does not work. Totally dead. I think the DSP and TWAMP cards are faulty. In order to do the circuit repair step by step, I want to ask you, is it possible to operate the pwm circuit by only feeding the AMPS card without connecting the connectors of the other components in a solid device? Ucc2893 pwm is used in dxr15. How many volts should stand 15.
I have the same speaker same problem. I'm hoping it is just a fuse or do these not work with a typical fuse? I'm about to tear mine apart and start looking around d
Great work,,, may i ask about my yamaha dxs xlf series module, when i turning the switch on I've heard a little sparkling noise and no power indication on led, so i turn off the switch and turn on again this time the power indicator come on and i can play sound even longer w/o a problem, i wonder what noise is it and how to fix it so that i didn't switch on twice every time i used it.... Hoping your respond tnx in advance.
U need to check some loose connection or dry solder in SMPS primery circuit side, if u r not a qualified technician i suggest you to visit your nearest service center Bro
Between the dbr Amplifier and the zlx line internal Amplifiers which one you would say is is of higher quality. That is if you have ever come across one of the zlx Amplifiers.
@@TKFElectronics i know but one is better made with better parts that is for sure. My question is from a professional point of view which one is best. Basicaly if you where buying which would that be. That is if you feel Comfortable sharing with me.
Thanks for the class. Is the power source Chaveada? At 110 volts, what is the limit on the outlet for down and up? Thanks.

@@TKFElectronics tnx for fast response..
can you provide de the name of the ic101 that appear in 11:46
ic no. L6599AD & it is improved high voltage resonant controller ic.
@@TKFElectronicsplease i need this ic can you send on courier service on Telangana
Bro what's app me ic no. along with ic photo on this 9653123582.

Would that be the same part number for a DBR10?
You mean main SMPS ic no.
@@TKFElectronics what would it be for the dbr10? Mine is blown right through!
My dear what blown pls describe proper electronic components name in order to assist you clear.

Both amp are good brother ...
Sir both brand internal amplifier is good. Both brand uses ic & MOSFET in amplifier board

@@TKFElectronics i knew it deep inside me i knew it.
Thx you made my choice that much easier.
Great work sir
Thanx bro
Bro i have this 2 board with burned power IC and FET can you help me ?
Yes sure why not, Tell me bro how can I help you
@@TKFElectronics i externally give voltage and on the board but no audio from that amplifier board pre amp section working prefect
hello can you give me the numbers below the integrated mine is not visible
Not understood your comment bro, pls specify in detail what exactly you r looking for ?
