    Optimum Resistor specs for ST-70? Empty Optimum Resistor specs for ST-70?

    Hey All -

    Apologies if this is a foolish question, but I'm about to order the resistors for my ST-70 project and I just realized that I don't know the specs I should be buying....1w or 1/2w? and the tolerance: 1%? 2%?

    I checked the parts list in the assembly manual, but since the parts were included in the it, they don't mention these specs: and I'm not sure where else to look.

    Thanks for any advice! Very Happy

    Thanks Peter - Much appreciated.

    I should have said (but of course I forgot) - I'm going to buy a VTA driver board for the amp, so I'm only looking for resistors for the rest of the project. I'll go to the schematic and have a look to see if the non-PCB resistors are marked.

    Just buy 2 watt 5% resistors. They are cheap and you'll be sure to not be undersized.

    Awesome, thanks Tubes4ever! I'll do exactly that. Very Happy
