EBC81 (EBC81) 1959 or 1957? (17.12.2005) Mario Coelho	Clicks: 422 Replies: 1
Dear Friends I try to create a new model of a CALYPSO MAMBO. Then I noticed that one tube (the EBC81) could be invented in 1957, not in 1959 as is indicated in Rmorg, in this tube models's page. The reason of this alert is because in CALYPSO schematic diagram is written that this schematic was drawn in 1957. I couldn't uplowd yet the schematic of this CALYPSO MAMBO because it was not accepted yet, but one can see the same tubes in CALYPSO schematic which was drawn also in 1957. Also I've here one Mullard Radio Valve Manual printed in 1957 where I already can see this EBC81. Best Regards Mário More ...
