Tube Identification Help
« on: 28 Sep 2016, 03:08 pm »
Looking for some help with some tube identifications.  I have some basic info but I'm not sure how accurate it may be.  Any help would be greatly appreciated.

First up a pair of Sylvania 5751 tubes.  Label reads a code of EBD C10 (?)  Triple Mica, black plate, square Getter?


Second set I believe is Telefunken ECC83 Grey Ribbed Plates.  Date code of 2C (02/1961 ?)


Third set are RCA JRC-5814A, code 65-30 (?)


Fourth set I believe are Cifte 12AU7s.  Code says 7135 AUA


The last set I believe are Amperex Holland, labeled Electorhone.  Code is AY A6 PH.  Note the lack of getter flash on 3rd tube.

No one :scratch:  Can anyone recommend a source I could send them for ID help and testing?  I need to part with them but would like to be confident in their ID and quality so as to avoid confusion or dissatisfaction.

Thanks,
Jim

Thanks guys!  I will look into this.  Jim McShane is on vacation for the next two weeks.  I'll give TC Tubes a call.  Much appreciated.

  • To whom more was given more will be required.
    • Never go to a psychiatrist, adopt a straycat or dog. On the street they live only two years average.

If you will sell these tubes there is no benefit in sending these valves for testing, unless the test tech is located in your city and you can bring tubes on hand.
=Ship expense
=ship may damage tubes, even after test in return
=If a tube tested bad, what you will do?

I have used antique radio salvage on ebay before.  He provides a detailed test report of each tube including noise level and is quite helpful.
