STV280-40 CV1068 Marconi Multiple Voltage Regulator Tube

£11.99
Weight: 400 g

Another weird-duck British tube, this one is a  multiple-voltage regulator... a gas shunt regulator tube that provides regulated voltages of 280, 210, 140 and 70 volts DC at 40 ma, thus making it useful for preamp/driver circuit projects or circuits that need multiple regulated bias voltages. Very cool looking in operation, too!

Nice 1960's vintage genuine Marconi British made STV280/40 CV1068  Stabilovolt tubes. For more information, see : http://www.mif.pg.gda.pl/homepages/frank/sheets/126/s/STV280-40.pdf

These tubes use a B4 British 4 pin socket, if you need sockets to go with thse tubes please see socket section.
