Cleaning the power supply

Simple cleaning of the computer power supply from dust.

Why there was a damper on the fan - I do not know. In my opinion, the damper is pure nonsense.

Alteration of the power supply of the TR-4 multitester

Modern multitester-oscilloscope-generator - https://ali.ski/7rsoI.

The tester was powered by a crown, which is quickly discharged from storage.

For power from an external source, a stabilized 12-9 volt DC-DC step down was supplied.

Before installation, the DC-DC was set to 9 volts with a load of 470 ohms.
