[khalsa]

Nice work sandeep kayarkar

 

[wattaniya]

sir
u mean this pin?

yes. that is the pin u have to cut in the relay.

 

[sandeep kayarkar]

yes. that is the pin u have to cut in the relay.

is that thermal sweetch is nessesery to use for test only?
its not available in my city.

 

[wattaniya]

for testing purpose no need thermal switch.

 

[sandeep kayarkar]

Help me out,

last night i power up amp using 48-24-0-24-48 but when i power it up test voltage i got just 9 v on H+ and 3v on M+, but without load traffo giving 120 v on H+,60 v on M+.and 1 more thing is I am using U1560 instead of mur1560. is that ok or i need to change it?

 

[sandeep kayarkar]

Cheshta's M10 working good, sound is low but clean and clear.

 

[sandeep kayarkar]

hello Friends. M10 is not working fine,
clip LED blinking at just 30% volume, i am using 80-40-0 ac.what to do?

 

[djk]

So what is the output voltage at this 30% volume? Into what impedance?

 

[sandeep kayarkar]

8 ohms 300 watt P audio speaker

 

[sandeep kayarkar]

about 40vac

 

[black]

sandeep tension uzualy is 140-70-0-70-140

 

[sandeep kayarkar]

its 80-40-0-40-80 10 amp

 

[black]

sandeep tension uzualy is 140-70-0-70-140

 

[sandeep kayarkar]

but cheshta says i can power it up at that ac V

 

[black]

for power that they bring to the tension that not worth doing class h power that is worth it's up to 1000W

 

[sandeep kayarkar]

I found some thing, may be its wrong, i found 10k 5 watt resistor hot on output driver pcb.
its normal or something wrong? need help.....
thanks

 

[wattaniya]

its normal, 5w resistor is 15v zd ic regulate resistor.

 

[black]

sandeep going well now you can put a video amplifier?

 

[roger sinyo]

i want pcb layout please sir delivered to rogersinyo@gmail.com

 

[azlospux]

where can i get link to this amp, would love to make this amplifier
