Extra Large Variable Inductor - High Voltage & Power (Watts)

Description

Here is a VERY large variable inductor. It is wound with flat copper bar and it has two rollers for best contact. I have no way to measure, but my research on-line indicates it is around 44 micro farads. With its size and the way it is made, It is for high voltage and high RF (kilo watts). I have been told this type of inductor was used in Power Amps like the Henry 4K. If you can verify this, please let me know. It measures: 9 /3/4" from front mounting hole to back mounting hole. It is 4 1/2" wide & 6" high. Looks like the shaft is 3/8".  It has a large ceramic coupler. It is very heavy. Since I have no way of testing it, I am selling it Sold AS IS, No returns.  International buyers welcomed.
