SG Junior 1965

Tone stack removed. 130Vpp sinus without noticeable distorsion (400mVcc at the preamp input). Above : 31Vpp

When signal injected to grid1 of the 6V6 is greater than 31Vcc, there is a grid current limiting (see positive alternance)

Grid current limiting. Taken on grid1 pin. 10V / Div, so positive alternance is 15V (for 16V at the cathode in K-bias)

Top : 6V6 grid1 – Bottom : 6V6 anode. Cut off comes before grid current

Top  grid1 6V6 (grid current) – Bottom : cut off and grid current amplified at the anode. Anode : amplitude +75V -100V
