Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Yes, I can see that in a totem pole,

-seems to me that is one reason many of them use feedback as that will reduce hum.

I've never been a fan of totem poles as they are often higher distortion and need the feedback just to work (though it seems to me there was someone on the OTL forum who had a zero feedback totem pole amp that he built as a guitar amp). I prefer instead designs that don't need feedback in order to work right, so the feedback is optional.

So the bottom line seems to be: '*Some* OTLs might be more hum-prone.'
