[Amps] LK-500 ZB

[mike stokes]

Hello
I have a Amp Supply LK-500 ZB and yesterday it made a big bang and blew
both fuses.  Now when I power it up the meter says it is drawing about 300
mA while sitting idle.  I have performed a visual inspection and there is
no visual evidence of anything being wrong.  I bought it used, so it is
uncertain if the power supply has ever been rebuilt.  Any thought were to
begin the troubleshooting ?  Is the p/s board worth rebuilding or should I
drop in a Harbach replacement board ?

Comments appreciated.

Thanks in advance and 73
