The part number is the same on the package and the BOM, but those that are shown as 1/2 watt in the BOM are shown as 1/4 watt on the package description. Likewise for 1/4 watts that show 1/8 watt on Mouser package.
Is this a cause for concern? I’m a newbie and of course don’t want to ruin my ST-35.

Thank you!


Chris, I believe you are referring to the RN65 and RN60 series resistors? These bulletproof resistors have two ratings, and the smaller value is a 125C Milspec rating. See two columns in the datasheet. So you are A-OK.

A great source for tubes is Jim McShane. I got a matched set of TungSol EL84s at a reasonable price and they sound great!
