Hello, all.

I am working on a Kolster K-20 and need to replace two out of spec resistors on the ceramic multi-tab resistor labeled z1 - z6. Two questions: Will 10 watt resistors be over kill and, assuming I replaced all of them, is it rebuilt the same way as a candohm resistor?

The schematic is here: www.nostalgiaair.org/pagesbymodel/092/M0040092.pdf

Thanks.

Dave
