Powering heaters with a constant current can require an inconvenient voltage level. This calms their mood and physiological sensations.

It may take up to a minute to drain the current to a safe level of less than 30 volts dc. Press them harder and hold this pose for 15 seconds.

If you use plastic speakers jacks, solder a ground wire to the jacks and bolt it down to the main ground point your power tube cathode wires may be on the circuit board or leave the tube sockets and go right to the main ground point This calms their mood and physiological sensations.

If you use plastic speakers jacks, solder a ground wire to the jacks and bolt it down to the main ground point your power tube cathode wires may be on the circuit board or leave the tube sockets and go right to the main ground point For practical reasons in soldering, it should have room for many wires to be connected into it using good soldering practices.

The audio ground is connected to the power ground at a single point (usually through the bus bar if you look at pictures on this site) and the power ground is tied to the chassis and safety earth. Clench your hands into fists, then release the tension.
With careful design it is possible to satisfy. Clip the probes ground wire to the chassis or ground point and touch the probe tip to the filter caps positive terminal to drain the stored current to ground.

Ask them to breathe slowly and deeply. Copper wiring used for building amps typically has a resistance of 30 to 150 milliohms per meter.

This ground contact point is made at the input jack. Clench your hands into fists, then release the tension.

Isolate the input jack(s) from the chassis and run the(ir) ground wire(s) to the local node of the gain stage that they feed. Accidental or unexpected ground connections, or when two or more appliances are connected together (see section 15.9).
1) one ground point for preamp including the preamp cathodes, and the preamp filter capacitor. Sometimes noise is a sign of tubes going bad.

With careful design it is possible to satisfy. This ground contact point is made at the input jack. Therefore, that makes for approximately 3 to 15 milliohms for a 10cm length of wiring, and if 100 milliamps of ripple current travels through this line, an ac voltage drop of 0.3 millivolts to 1.5 millivolts takes place.
Powering Heaters With A Constant Current Can Require An Inconvenient Voltage Level.
2) one ground point for the two power/reservoir filter capacitors, the power tube cathodes, and the center taps from the power transformer. This is to check their level of orientation and to start to bring them back into the present. Use only one end of the shield inside equipment.
How To Use The Grounding Technique.
There are actually two important aspects related to proper grounding, hum reduction, and safety. If needed, run a separate ground wire to the volume control or where ever the signal is going. If playback doesnt begin shortly, try.
Sometimes Noise Is A Sign Of Tubes Going Bad.
It may take up to a minute to drain the current to a safe level of less than 30 volts dc. Generally the screen (outer) of rca should be isolated from the chassis/case for audio, ad find their ground at the appropriate place in the input circuit. Press them harder and hold this pose for 15 seconds.
