Kenwood Hybrid IC KMA01

wuffwaff · 26th October 2011, 08:46 AM

Hi,

my old Kenwood CS4025 scope gave up last week. After searching for a while (which is quite difficult without a scope) I think the hybrid ic KMA01 is faulty. I looks like there are two opamps, a small cap, a fet or transistor and a resistor on it.
The simplest thing would be to get a new (used) one. The alternative would be to build a new one.

Does anyone know where to get a new one?
Does anyone have a schematic of the KMA01?

Thanks,

William

Hi William,

I have same problem with a scope CS 4025 too. The source is with voltage values different in relation to manual service Kenwood .

I don't find high voltage in TRC.

and i don't find nothing about KMA01
