page 7-35 and 7-37 underAs I point out in another thread, you can use the Gr grades with much the same quality, and with little or no adjustment. Also you can use the Linear systems parts, including their a grade.
Much of the cost of some of these parts is due to audio guys wanting perfect matching, which is usually not necessary. In addition there are some cheaper surface mount parts.
Finally you can use parts like J113 and J176 which do not have as high a transconductance or low distortion or noise, but which will can still sound good and are cheap. Members here will probably mention their own alternatives.
Which things and on this pages ? - go to page 131-219 under"The Art Of Electronics" has VERY flattering things to say about the J107. Which is one reason why I bought 500 of them a few years ago.
