Off to Mouser...Mark, found my old post. I have a 1W 121ohm Dale 1% on each leg in series. Nothing on the center tap.
Have you snubbed the bridge rectifier and considered inserting ~10 ohms into each AC secondary leg where it connects to the bridge?
You have every harmonic of 60Hz represented in your spectrum analysis. 60, 120, 180, 240, 300, 360, 420, 480, 560, 600, 660 is quite muted, 720 and so on...
You don’t want any resistance in a power amp application. Zero...Hey Joe ,
Would inserting 10ohms on the ac lines to the bridge on a 400 / 700 reduce 60hz noise any appreciable amount without cutting output power ?
