Today, after having finished alignment of the previous 38-12 in a veneered wood cabinet, I proceeded to the next 38-12 in a painted white wood cabinet.

These are the initial photos of the cabinet.

   
   
   
   

The chassis is a bit dustier than the previous one.
   
   
   

Under the chassis there are some mediocre quality repairs.

   
   
   

I checked the AC input, and it looked like it was open. The switch on the pot (which is a replacement pot) was not making any contact at all.
When opened, it was fully oxidized.
   

After using alcohol and then some Deoxit D5, the contact was restored.
   

I thought of trying to put it on Variac, but then thought I needed to check the tubes. The 75 tube was barely alive. Judging by both the triode and the diodes were super-weak, it is emission. I have a good tube. The rest of the tube are OK.

I will start with the recap tomorrow.
