I have this gem from yesteryear on my work bench for restoration.

First I fixed the power amplifier situated on the bottom panel. There was a loose wire to the PL84 heaters and the bias was wildly out causing red plate on the Telefunken's.

After adjusting the bias, things seemed stable, and I moved on to the pre-amp section.
