Up next in the tube preamp series, I give you the Orange AD200B MkI. Made in very limited numbers, only a few hundred if that, in 2001 these were made P2P on turretboard. Known for great clean, with a focused midrange, but has great grit with the gain cranked.
Unlike the Sunn Model T, this has not been breadboarded and tested out, I just followed the same concepts Ciaran and I used to convert the Model T preamp to use FETs. This means at this point, there may need to be some tweaking to component values to get it just right.
One thing to note, as I didn’t put it in the build notes. All the pots are dual gang pots, with each corresponding lug connected. What this means is lugs 1a & 1b are connected together, 2a &2b are connected together, and 3a & 3b are connected together.
Edit: Putting this on hold until i can get some time to breadboard it and get it sounding right.
