Yep, the 5687 has two triodes in it, so it does both chans.

I used to like how Quad did their tone controls. Seemed to be more use for taiming problems recordings

Yep, maybe I should rephase that. There are more complex bits of maths in there, but you don't miss much if you just scan over those bits, but IMHO, if you leave out ALL the maths the book looses some of its value. But even if you don't understand something, you find (I know I did) that when you com...

Yep, as long as you are not allergic to some simple maths, the first one of those will teach you 95% of what you will ever need.

I will see if I can put a phase splitter together this weekend.

Nice. Just checked with the ata sheet, 15v is the expected number
