Accuphase E-205 Repair and Tuning

Repair

Looks like the relays for the speaker protection are gone. After 23 years no surprise.
Since the OMRON G2Z-222P-US 48VDC is not avaiable anymore I have to choose the following:

SCHRACK RT424048
Avaiable from Manufacturer: www.shop.schrack.at

The problem was that the old relays have a total different layout than the new ones, and come in a different size. Here you can see what I mean...the inner 6 points are the new smaller relays.

It is the total anti-design...its fun to design a adapter for that, especially since there is not much space on the PCB.

Cleaning and new Thermal Conductance Paste 

After cleaning the whole Accuphase, the output stages both got new TCP for their transistors.

New Electrolytic Capacitors

I will replace the old Caps with new Panasonic FC/EC Caps.

And as for the new caps. Here is a before and after pic. I had to rearrange the new big FC because they were larger than the older ones.
