Purpose

TentLabs heater supply is designed to supply the heaters of indirectly heated tubes. Its’ main use is feeding phono and linestage tubes, to keep the hum levels down. The module can also be applied to feed other circuits, like the CDpro CD driver.

Application

More tubes can be connected in parallel, assumed their respective heaters are at equal potential. If heater potentials are different, separate modules (and transformer windings for each module) are required. The heater reference needs to be connected close to the tube The total output current is limited to 1.5Adc, mainly due to heat dissipation. The units are factory adjusted at your order. After installation, the supply needs no adjustment.

Specifications

Electrical
• Output adjustable between 2.5V and 13V, specify when ordering

• Output noise < tbd uVrms (10Hz – 20kHz)
• Output hum < tbd uVpeak at 100Hz / 120Hz
• Output impedance < tbd mOhm
• Fast switch-off function available on request (required if used to supply 9V section of philips CDpro CD drive)
• The heatsink is not electrically isolated from the circuit and should be isolated from the chassis
• The output is not short circuit proof

Mechanical
• Total size 40*60*40mm (W*L*H, heatsink included, standoffs excluded).
• Weight each 60 gram (excluding packaging)
• Hole pitch 31* 51mm, hole diameter 3.5mm
• Needs 8mm stand-offs to mount on chassis, supplied with modules.

Pricing & warrantee

5 years of warrantee by Tentlabs (the Netherlands), assumed they are built in according application information.

Purpose

TentLabs filament supply is designed to heat DHT’s the cleanest way possible, without affecting the music currents generated inside the tubes’ heater. The supplies generate a very low noise output, while maintaining its’ high output impedance. Result areas are:
• Bigger soundstage
• Better focus
• Cleaner tone
• Better resolution

Application

A typical example is shown below:

Each tube needs its own filament supply, in turn fed by a separate winding from the power transformer. The whole supply then is floating, and only has one connection to ground, as shown above. This example above shows the DHT in fixed bias mode. When using cathode bias, the grounded leg has to be connected to the top of the cathode resistor instead.

These are the only connections to the filament, so no caps, no hum-bucking pot, no nada!

The total output current is limited, depending on the version, but they all start-up slowly. Especially when the tube is cold, this is a nice feature. Cold tubes, when heated with traditional supplies, draw currents up to ten times their nominal current. Using TentLabs heater supply will gently switch on your tubes.

The units are factory adjusted at your order. After installation, the supply needs minor DC adjustment, to compensate for possible voltage losses in the wiring (some 100 mV are easily lost at high currents). During use, no adjustments are needed anymore, not even after changing the tubes !

The new generation filament supplies has an over temperature indicator and shutdown, in case the heatsink-temperatue exceeds 90C. The LED and wiring is supplied separately with the modules.

Active Bias Supply Module (ABS)
Benefits:

• tube life is extended
• saturation of the output transformer is avoided
• amplifier always operates optimally
• better bass performance
• more dynamics
• minimized danger of runaway tube current when amplifier is unattended.
• Also since most bias voltage supply filter networks tend to be very simple single diode or half wave, there is usually a great deal of ripple in the most sensitive signal path in the amplifier – the grid! And active bias system is also an opportunity to design a bias supply with extremely low levels of ripple. This adds a sense of stillness and low-level detail not obtainable with standard bias voltage supplies.
• Compact 4 x 9cm. Easy to place in chassis.

Price is for one piece of modules which can actively supply 2 power tubes for single ended stereo (ie convert cathode bias to fixed bias). module can also be purchased as a pair which can be used to supply 4 power tubes for push pull.
