  • Notes

  • Our member Meyer Rochwerger, Brasil, entered the model page with European Rimlock tubes: ECH42 EAF42 EBC41 EL41 AZ41 with a triode-hexode osc.-converter. We received a schematic with EF41 instead of EAF42. It is drawn for date 8-7-54.

    We later received some origianal information from guest "moraess", Brasil which shows the US-tubes version with 6BE6 6SK7GT 6AV6 6V6GT 5Y3GT. Plan date is 1-8-1951. See pictures. It has a pentagrid-converter as heptode. But there is also a model P-10 with noval tubes: ECH81 EF93 EBC91 EL84 EZ80. Therefore most probably there are three versions around because the tubes are not compatible. Neither pin nor schematic are the same.
