Piet (NL) brought me a "405" he bought second-hand for revision.
I have seen a lot of things inside the > 250 Quads I had on my working-table but this beats everything.
The circuitsboards were replaced with Sanyo STK070 solid-state 70W amplifiers. It is clear that this way the 405 specs are far from being met.
Furthermore the internal wiring is a total mess.
One should always ask to see the inside when buying an amplifier second-hand.
We will build this 405 again, bottom-up, with 405 driver-boards.
It looks a lot better yet, doesn't it?
To be continued...
