Hello everyone,

This is the same circuit with the modern silicon transistors.

To build this circuit, you’ll need a few more connection blocks then included with the base and expansion set.

If you compare the 2 versions, you’ll see the advantage that the legacy transistors have : they have the bias resistor incorporated which saves a lot of connections.

We also have used for R7 a 100K resistor instead of the 330K for biasing T1. Do you think the sound produced will be the same ?

Try it out and compare the results !

Greetings
