The CV6045 is a beam tetrode designed for stabilised power supplies and DC control applications. The ratings are absolute maxima and based on producing stabilised HT rails, when operating as a series pass valve.
The CV6045 looks to be an enhanced version of the 13E1.
Series pass operation implies working all the time at a high percentage of the maximum cathode current and is consequently very demanding on the cathode. The normal solution is to provide large cathode areas and generous heating power.
The all glass construction. The two cathodes are seen as flat white objects.
This view shows the anode. Each anode half has a side fin and these are seen end on in this image. The two halves are joined at the centre to the support rod.
This image shows the twin sections. The anode thickness is substantial, the cathodes are wide slabs and the control grids are gold plated and fixed to thick copper supports. The screen grid wires are aligned to the control grid and pass across both sections. The beam plates are the bright rods seen in front of the control grid wires.
The wide glass tube envelope is 64 mm in diameter and, excluding the B7A base pins, is 120 mm tall.
Reference: Datasheet. Type CV6045 was first introduced in 1960.
