vidor: CN396A : Alternate valve / tube line up

Mine has 1R5 (RCA USA), 1T4 (RCA USA), 1S5 (Emerson USA) and DL94(Mullard) rather than the DK91, DF91, DAF91 and DL94.

Are the US tubes imports used as replacements after sale, or Factory alternate sources?

The maker label is very clear on the 1R5 but the actual "1R5" is missing. I notice on the 1T4 that the "1T4" is different much fainter ink than the "RCA made in USA".

Hello Michael,

Trader sheet 981 lists the Mullard valves as per the model page were fitted in this model, and no alternatives are mentionned. I suspect that they have been replaced with those US equivalents at some time,
