Re: Another 7D20 attenuator question

Hi HÃ¥kan,
Get all the attenuator errors on boot, but all relays are good. As stated by my first post I believe that the substrate board is the cause.

I noticed that the 'A12 & A13 'substrate PCB' has tarnished relay contacts. they are a dull gray (lead?). I thought Tek gold plated PCB contacts for non corrosion and good contact resistance?
Shouldn't the contact pads be gold plated?
