Saw tooth

The constant current source pnp transistor is reverse 😉 nice little circuit

An anode gate thyristor we have here i see. I like this thyristors not only to use them for triggering a big bro cathode gated thyristors. Damn good little devices for any type of switching due this voltage controlled triggering point feature. Once i construct a simple mono synthesizer coupled to simple digital 16 step sequencing thingy. I use them for construct a double saw with variable detune function. And they sound sweet well. Harsh acid like ol'tb303 but When compared to double saw generated on modern subtractive synths like access virus or novation i was shocked because this one generated by put ,s was far much more juicy and pleasant than one generated in ultra modern dsp processors.

I found this design on youtube. I hope it's useful or inspiring to others too. :-)
