| Descripción |
90V 1-40mA. Dual marking for 85A2. Probably this code was assigned for a JEDEC registration of the 90C1, never completed.
The 0H3 appears on some North American supplied tubes with dual 90C1 and OH3 markings on the tubes and boxes.
The origin of specimens are from both the UK's Mullard Mitchan factory, and Philip's Heerlen factory. It is possible that these tubes were rebadged in North America.
In common with other earlier 90C1 tubes, they share the coding of the 85A2.
