| − | == Short description ==
| |
| − | External differences to the A-757 MKII: Golden dot now on volume pot, input and output selector switch. Inside: now vertically mounted circuit boards, thus free view through the bottom plate which is no longer made of copper, now also no honeycomb housing around the relay section and the RCA boards. No more type designations on the cast housings of the transformers.
