[sdiy] Latvian LM394 (was: CEM Synth IC clones)

[Michael Grossman]

I was wondering the same. I thought one of the key specs of the LM394 was the emitter-base voltage matching to 50 uV.
Thanks,Mike

In general it does not look like it was on par with the original one.          From: Synth-diy [mailto:synth-diy-bounces at synth-diy.org]On Behalf Of bbob
