I acquired 2 Dared DV-300b monoblocks. They are in working order, but inside 4 resistors (2 in each monoblock) have broken their casing.

I can't read their value, since their casing is gone. I have tested them with a multimeter, in circuit, and they both measure 83K ohm.

Would be safe to assume these are 83K? How about the watts?

On the transformer a sticker says output is 300-315v. I'm not expert and using this online calculator (Voltage current resistance and electric power general basic electrical formulas mathematical calculations calculator formula for power calculating energy work equation power law watts understandimg general electrical pie chart electricity calculation) inputting only 83k ohm and 300v I get out 1watt.

These resistors though seem very big. What wattage should I replace them with?

As you can see from the photo, the PCB around the resistors is burned and the nearby capacitors did melt their plastic wrap.

The person I got the amps from said the PCB were burned already years ago, but surely the burned got a bit darker year after year of use. It seems that the PCB already went through some repair, as there look to be some sort of patch under one of the resistor.

These particular units have been modified by Response Audio. I have tried to contact them, but so far had no reply. Dared has not been able to provide me schematics either, so I'm not sure if these resistors were part of the modification Response Audio did.

Thanks in advance for all the help!
