Hum in MTI SVT power amp.
#1
Hi

My brother has a made in Japan SVT and it is for the most part a power house of an amp. I recently checked the bias and thought the amp has a lot of hum. I worked out most of the hum is in power amp stage. To be specific the hum is being largely generated by the first triode.

Here is a link which shows what I've already tried. There are pictures and waveform displayed.

Thanks for reading my thread.

Kind regards

Mark
