-
The model Erres 6621AT is a transistor table model with highly polished wooden cabinet and plastic front. The two pin mains plug, when not in use, can be inserted into a socket on the rear to enable battery operation. The arrangement for tuning is interesting as as the small brass device below the variable capacitor drive drum is a single plate trimmer operated by the smaller tuning knob on the front of the set.
Push-pull output stage with 2x 2SB156A; all transistors are made by HITACHI but marked with vdHEEM (van der Heem).
