Technics SU-8044 repair

Never mind slackers I got this last one sorted out but I have a new problem.

Resistor #R511 is scorched. I replaced it and it is getting hot and showing some volume on the meters when I put the function knob on Phono. The Service manual calls for a 1500 ohm 1 watt resistor in that spot and I replaced the old one with a 1500 ohm 1/2 watt because that is all I had on hand. Is this causing the overheating issue?

At this rate and this temp the new resistor will be fried in minutes. There is a Zener and another resistor next door.

Any idea where to go from here?

Without having a schematic to look at, I can only give a vague "something after the resistor is drawing too much current".

If the original 1W resistor fried, a 1/2W one doesn't have much hope of lasting. But the lower wattage rating is not the source of your problem.

Even the S Manual on Hifi Engine says Low Resolution next to it. I just can't read the damn this.

I'll check the transistor next door.

Thanks
