PSS-100 CASIO, What Beep?

Here is a schematic showing the ICs used in the PSS-100. We recently modded one to add pre/post power amp outputs. Jess also routed the beep so that the audio outputs remain cleaner but the speaker still has the beep if needed.

Please take care of each other.

Tele-Trainer Update #2

.

The buttons make the ringing machine work with phones plugged in, however no ringer, dial tones or audio. Next step is to get the phones and speaker up and running.

Please take care of each other.
