Good day
Dear gents

Which project is better for DIY?
Original 47lab or Audiosector?

Original 47lab amplifier

Neither. Simple mod makes it into transconductance amp. Sounds better to me.

CAn you even find an LM3875 these days?

My Audio Sector based amp is quite decent.

I have an audiosector premium kit. The input impedance is set by R2=22K. I need an higher Zin because my tube premp doens't like highsh Zin

Do you thing 50K, or higher like 75K - 100K is possible?
