Hi y’all, long time lurker first time poster.
I recently came across (snigger) these ICs from China,
5 PCS LA3607 3607 7-Band Graphic Equalizer @ £1.88.
Used the datasheet to make my first proper vero, seems to work ok,
if anyone is interested or has any tips for the layout please let me know.
I used this site to calculate the Frequencies
http://www.muzique.com/lab/gyrator.htmR1 – 68000 (68K) & R2 – 1200 (1K2) as per datasheet.
I’ll attach the DIYLC v2 file & Datasheet
Apologies to IvIark for the standing resistor (lol).
