Hi,

it's been a while since people are posting about the XR.2206. There have been some talk about the replacement for the LM394, but neither can I get any SSM2210 nor the Mat-02 here locally. Some people mentioned using the 2N3904 as a match pair. I don't really understand what this means and how I should add it to the board. Can someone share some information about using these? or what other alternatives can I use in replacement of the parts?

best

See my post here:

Last post (at least at the time of this post Very Happy ).

Basically, you need a very small pcb, which fits on the DIP8 footprint, onto which you solder the matched SMD device(s). In the layout I posted on muffs, there's also room for the tempco resistors (Panasonic SMT devices).
