Tech Signal Generator TE-22D Circuit - UK Vintage Radio Repair and Restoration Discussion Forum

Hello there,

Can anyone assist with a circuit for a Tech signal generator TE-22D (two valves, 12AU7 and ECL82). Sine wave output is fine but no square wave at all.

I have downloaded a circuit for the TE-22 but this is rather different (three valves).

thanks for any assistance

Bruce
