Hello
Can I put capacitor 1.5nF (MC7.5 1K5) block but it's with 630V ?

Hi Kazem2114
ALL explained IN PIC. IN CASE DP.(NOT IN U TEST)

Thanks but the things that you're saying , it looks like we have 2 voltage source
one to give +12v
one to give -12v
because the voltage of negative prob of a battery is not -12v , it's like ground
Am i right?????????
There's no circuit for making -12v in the schematic

-12 goes to your battery minus clemma. +12 goes to your battery +12 clemma. WHAT IS NON-CLEAR THERE FOR YOU??

Hi Nikolov
Do u mean C4,C5=1.5nf /63v~100v and u do not get u can use 630v but big!!!

Yes C4,C5, there are in Sense circuit, but I can't find with 63V in the shop have with 630V currently I put ceramic capacitors and this is not good solution!

Hello dear KT315
I used a this pcb , But has no sound ,
please guide me
Thanks

[kt315]

hi Belief,
you can try to reach the sound via a way I offer. make like this you see on the diagramms and find the problem

Hi to all

Is it possible to replace Irf 740/840 by IRFZ44?

Good day

NO.

Hi to all

Is it possible to replace Irf 740/840 by IRFZ44?

Good day

Possible sure but with much, much, worse performance. Its only 60v! Look for higher voltage capbilty and low output capcitance if your looking to upgrade.

Thank you Kt 315 and Midas

It was just because I have IRFZ44 in stock but I do not want to reduce performance .

Hi Freddy67
You can not use it for the following reasons,Different values of voltage and resistance entry gate is too small 0.024 OHM BUT IFR740 IT HAS 0.5 OHM, you must modify the income by using Tr,R.Final value of the Volt must 600v.

Hi Jap
Thank you for this explanation with sketch . I shall have to buy one 740 or 840

Best time to you

This was a complete kit that I bought. I was told to jump PR1.

Hi sparky
dont turned it on ,,,,,,,
-Change irf740
-Change d9,10 by CD ,HCF,,,4066 .not M74HC4066B1 its RONG.

Change ifr740 to a new one?
Change d9,d10 to regular 4066 chip?

Jap.. are you with teknolojlekibi.com?
