HARTKE A70 limitter issue

[rextor]

Hi guys,

This is my second Hartke A70 with Limit problem. It has been plugged to 220vac outlet before and after replacing the fuse..The"limitter" indicator never turns off.

You mean a Led labelled "Limit" lights and never turns off?

I guess that's the least of your problems.

Does the amp work?

Nope, it doesn't work..no audio coming out.

Seeing that the unit saw 220V (assuming it was strapped for 110V) you should start at the beginning.
The power supply.
Check that both main rails are up & running.
And the + & - 15 volts.

Hi,

I've got +1.138vdc across c60 and -14.77 on C61.

O/k.
The +15 volt regulator is low.
How about testing before the regulator output.
The V+.
