Hello Henk,
This components seems to be added by someone. I've own two of these amps, and there was no components inside like yours. If I remind good (!) this place is dedicated for mounting impedance adapters (transformers) like in the EL6435's.
Be careful with the "cubic" filter capacitor! In my amps, one was defective, a black juice coming out... I think you know the problem if it goes in shortcut... AX 50 rectifiers (here, two in voltage multiplier) are hard to find and expensive !! I've replace it with a permanent motor capacitor. It's not so "vintage look" but it works ! I wonder why they have use a non-polarised capacitor: it works in DC at this place?
The output tubes biasing is very particular in these amps... I've never fully understand it.
This two amps are property of Patrick Nagtzaam, now. He's sometimes on this Forum.
Greetings,
Thierry
