Hi,
does anybody know the values of R1, R2, C1-C28 of this circuit? The schema just says “to be selected”. Does this mean I have to try it out? Are there any known “near” or “start” values to start simulation with?
Thanks in advance
Carsten
I don’t know how much help these will be, but here’s 32 high res photos of a 914 from most angles.

Also, all you really have to do is make one of the filters and modify the R/C constants to get the frequency desired at the highest amplitude.
The choke has to be close to whatever center frequency you’re trying to achieve, but past that you’re basically just trying to peak the gain at that specific frequency.
Thanks for the pictures. I identified some capacity values, but I surely will have to do some spice simulation to get the rest of them.

Perhaps a start can be found in the inductor version of the 907 JH’s site (Very sad about JH)
