Yes it is a Brimar tube made by STC (Standard Telephone & Cables).STC started in 1883 as an agent for Western Electric

So am I right in saying that to use the Sophia or KR PX-4 with the BA, all you have to do is change the voltage from 5V to 4V?
rosgr63: What power tubes are you using right now?
Anyone try the Shuguang Treasure 300b?
My Balancing act will be arriving today! I have loads of 6sn7 to roll: Ken-rad VT231, RCA VT-231, Sylvania 6sn7gtb, RCA 5692, Sophia 6sn7, Shuguang Treasure cv-181z, Brimar cv1988....but not the Tung-sol round-plate...are they really that good?
