Hylight DR103 PCB

Here's pics of the DR103 i used to own--- a PCB Hylight DR103, Canadian specs, that was a little worse for wear when i got it.
It had oddball gain mods and a power resistor had blown on the Power Supply/Output section PCB board--- you can see the scorching in the pics---- i put the preamp back to near stock (i left the additional preamp cap--- one section of the 32/16 can was bad so they just added another cap instead of replacing the dual section can).
I also left the not-so-neat bias pot job in place--- it worked ok.
This was my 1st real Hiwatt--- i wish that i had known more about amps back when i had it---- i probably could have gotten it sounding better than i was able to at the time.
I sold it on the bay.....................gldtp99
