6AC7 VT112 Marconi, one pair, true NOS/NIB, super rare, for Fosi GR70

Description

One pair (2) Marconi/GE Canada 6AC7/CV660/VT112 tubes. The tubes are abolutely new and in  fully working condition. Tested and guaranteed.

All tubes have close production codes and test excellent. Tubes come with brown bases and grey metal ring for the socket. Tubes will be paired in terms of transconductance for good matches.

Some boxes are printed “Marconi Canada” others “General Electric Canada”. We assume that all were made by Marconi but some got rebranded for General Electric (see pictures). Other than that the tubes are absolutely the same.

We reserve the right to deliver either version depending on availability.

Very limited stock available of this unusual and rare version of the 6AC7.

The tubes come in their original brown military boxes. Boxes are somewhat torn due to age and storage conditions.

These tubes are guaranteed to be new and unused from old military stock!
