Constant Current Source Constant current source or sink (CCS) is one of the very useful circuits for amplifier building. They can be used in power supply, act as loads, bias tubes, form a differential circuit and etc. I use it a lot in the tube amplifiers I built over the years.

The source can supply low noise constant current starting from as low as 1 μA to a few tens of mA with a high voltage compliance limit of around 20 Volts. The constant current source has several stages which can work in a standalone manner or together to supply the desired value of load current.

Reference Constant Current Source for DIY Audio and beyond (and anything else that requires the really good CCS :)) - I have this project under development. The "magic" CCS promises to have quite outstanding parameters: I nominal as from tens of micro-Amperes up to 400 mA (subject to some 50W power limit)

MONO AND STEREO HIGH-END AUDIO MAGAZINE DN2540 High Voltage Constant Current Source Ever dreamed of getting the highest possible linearity out of your triode gain stage, by means of using an extremely high value of an anode resistor, say 1 Meg or more?

Constant Current for Tube Heaters. Extend the Life of Your ...

Constant voltage (rather than constant current) is the most common vacuum tube heater drive technique. Power transformers for tube amplifiers are commonly made with 6.3-V or 12.6-V windings to drive the amplifier’s tube heaters in parallel. Powering heaters with a constant current can require an inconvenient voltage level.

diyAudio Tube Constant Current Source Board Project The diyAudio.com CCS PCB is an array of circuit boards for constructing various constant cur- rent sources/sinks for prototypes or as modules in a final design. The topology of all the cir- cuits is the same- a cascode bipolar with an LED reference. I’ve found these to work really
