VT60A / CV1572 beam tetrode

Size This valve measures 142x50mm overall and has a 5 pin base.

This valve appears identical to the CV124 and indeed the datasheet suggests it was based on the 807. However it is listed separately and thus has its own page here. The CV1572 (bottom photo) also carries the 807 marking.
