Push In 50 mm / 2" Castor w. Metal Socket

Vacuum Tube Damper made of silicon, helps to reduce noise and rattle of vacuum tubes. But it will not turn a bad tube into a good tube.
If a higher level of damping is needed, than use more than one damper per tube.

• Inner diameter ca. 22 mm
• Can not be used with JJ 12AX7 and other JJ preamp tubes with similar diameter and JJ EL84 and JJ EL844
• Price per damper

BEFORE ordering check the exact outer diameter of the vacuum tubes and compare it with the diameter of the damper to make sure that the damper fits.

Set of metal corners for housing consisting of:

• 8 x Cabinet corner w/ cutaway 2 leg, silver (pe-c1824k)
• High Quality
• Powder Coated black
• Internal radius: 12 mm
• 16 x Screws, flat head, black

Kit of a bias probe for indirect measurement of the quiescent bias current of a tube. The adapter is placed between the tube and the socket and is connected to a standard voltmeter (not included). Pay attention to the quality of the meter and to sufficiently charged batteries!

The quiescent current is measured indirectly via a precision resistor built into the adapter. The advantages of this measuring method are harmless voltages in the mV range at the measuring plugs as well as short ways for the current, since it does not have to be led through the measuring device (common practice with many measuring adapters of Far Eastern production). As a result, there is no risk of oscillation of the amplifier, which could damage the tubes or the amplifier itself.

Note: This adapter cannot be used when additional tube brackets are installed. These must be removed before using the measurement adapter and reattached after the measurement is complete.

Measurement procedure
Determine the resistance of the adapter, including the test leads. Connect the adapter to the meter, but do not connect it between the tubes and the amplifier. Select the ohms range on the meter and note the reading, e.g. 1.1 ohms.
For the final measurement, insert the adapter between the tube and the de-energized amplifier, connect it to the meter, select the mV range and switch on the amplifier. When the amplifier has reached a stable operating condition, read the value in mV from the meter and calculate the quiescent current using Ohm's law.

Example
Measured voltage = 47 mV, adapter resistance = 1.1 ohms.
Formula (I = V / R) or in this case
Bias Current (in A) = Measured Value (Voltage in V) / Measured Value (Resistance in Ohm)
0.047V / 1.1 Ohm = 0.042A or 42mA

For the calculation of the correct bias current as well as further information on bias measurement please refer to further documents or the bias setting instructions in the info section as well as the manual of the amplifier itself.
This adapter is suitable for all EL34, 6L6, 6550, KT88, 6V6, 6CA7 and other tubes with the same pinout.

Attention HIGH VOLTAGE ! Measurements and work on tube amplifiers should only be done by qualified personnel.

Please note !
when you order more than 1 m and select Deutsche Post / DHL Parcel (Not DHL Express) we need to cut the width of the tolex to ca. 115 cm. Otherwise it is not possible to ship the tolex with DHL because the parcel length would exceed the maximum parcel length.

Cabinet corner leather black, Set of 4
100 % real letaher, vegetable tanned
Caution: natural product ! The texture and thickness may vary.

Hint: put the corners into water for a few minuties before mounting. This makes them soft and elastic and than they will fit better.
The corners on the chassis should be well rounded too in order to achieve best results.
