it's too rare,don't have chance to hear it.how do you think telefunken el84 sounds?

Hi shoot ,I,m afraid you asked the wrong person as I,m not a Telefunken fans,most of their valves sounds,to me lack the dynamic and slow rhythm and made music sounds lifeless,remember this is my own preference as their are a lot of audiophile like Telefunken valves.so do,t hit my head

Interesting leads! I wonder how these leads work??
This tube are intend to work without socket??
The wires seems to be solded in the circuit.

Hi FULLRANGEMAN!this can replace ecc82 or 6SN7.they are originally designed to welded on board.but now......

Thanks for inform, Its a very Hi-End feature, no sockets, no dust, no bad contact, just a permanent solder.

That's why they are no best sounding valves in the world, it might be my system sounds slow,specially the speakers.but hope is not my ears problem.

I think it is Philips Heerlen K5B Delta 5

the code is on the bottom right? philips heerlen's mark is delta ⊿ and never made welded plate ecc82,83. philips Copenhagen's mark is a triangle Δ,they made welded plate ecc81,82,83 from 1951-53. the mark are similer and made many people  get confused

[adrianc]

You could be right as the printed are hard to see,might be triangle rather than delta

What about these Delta 8 MCB welded plate?

What about these Delta 8 MCB welded plate?

Can I see their bottom picture?I think they are all made by philips Copenhagen in oct.1953 ,If you got MCA ΔA(or B,C,D,E) that will be one of the best ECC82.  never heard philips heerlen  made welded plate ecc82,83.

The stamp looks like a triangle but printed made in Holland,wrong printed probably,  Believe it or not I broke three of these ECC83, FXXX

Never mind that "made in holland" print,they often print wrong. inside stracture and code is the only basis.

broke those rare old tube is a crime,should send you to jail

Thanks for correct me and this printing looks like Mullard
