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.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
