Harmon/Kardon 150+ Biasing

OK. Another success story from re-biasing.
I’ve posted this Harmon/Kardon 150+ a couple times over the last year. It’s always performed really well as is, but it’s performing much better tonight after re-biasing.
All four channels of this quad receiver were low, three of which were extremely low and out of spec.
Bridged into 2 channel mode, which is the way I’ve been using it, it is significantly more powerful.
Watch the entire video if you want to see what I did to re-bias, it’s the most OKish video production you’ll find!

Hello Mark, Will this receiver be up for sale, and in what State are you located? Thank you for the biasing tutorial 😏

I don't know why, Mark but your voice is really soothing and I find myself watching just for that. 🙂 Also, thanks so much for the incredible Kmart tape collection you uploaded. It's also very soothing for me having grown up in the early 80s listening to those. Things that were so random as a kid are now very warm memories.

Thank you, now that’s a first!! Maybe I should get into ASMR.
