Anybody help identify these tubes

[davew]

Hi, I have been given some Toshiba tubes marked 5B they are 7 pin and come out of a Sony Tape recorder, I was also given a pair of output transformers for these (8ohm sec 2.5k primary).

I would like to build a small iPod amp for my daughter using these.
Can anybody help me with any technical info on the pinouts/specs?

Thanks


Dave

You could look here
Duncanamps
for 7-pinners.

Thanks for the suggestion but unfortunately no luck

If it helps anybody I have found out it was a Sony TC200 tape recorder

Tube 5B

Hi,
I can find some info in a Japanse tube book about Tube 5B (Electrons) Type : 2R+2R , Ef (V) 2,5 , If (A) 12 , Ep(V) 120
Ip (mA) 5A

I don't know what is 2R+2R ? ? ?

I suppose that "Electrons "is the make , it is not " Toshiba ".

Hope the above info helps...

I've also the same reel recorder, Sony TC200. I 've never opened the trunk so i don't know either the tube types.
If you find any info's about them or better a service manual, please let us know.
