Francisc VISKY 12.Oct.07	1 er56 Here is a nice vacuum tube: ER56, Eveready Raytheon, 4-pillar radio tube. It looks like a triode with cathode. See pictures. Looking in RM it is not founded.
Konrad Birkner 12.Oct.07	2 ER ER is often found as a prefix for Eveready-Raytheon tubes. Yours is just the same as a common 56.
Francisc VISKY 12.Oct.07	3 ER56 It looks different and it is from an other manufacturer. Where to upload?
Ernst Erb 12.Oct.07	4 ER56 Dear Francisc Nice that you have asked. In the meantime Konrad has installed the ER56 and we would be glad if you upload your photos to the tube. Cordially, Ernest
