Suitability of ECL84 tubes for audio

[lquintas]

Hi phildas

For my PCL84 amp I used Hammond 125ESE OTs. 10 K - 8 ohm connected. They are not very beautiful but they sound very well. They cost 65 $ each. See the characteristics at Hammond Mfg. - Universal - Single Ended - Tube Output Transformers - (125 Series)

thanks for the reply!

Any details as to how something like this can be custom wound?

Thanks!

With great care and some trepidation.

Reading this thread will give you some idea. It takes specialized talent and knowlege to wind a transformer safely and properly.

Ecl84

the pentode section of the PCL84 / ECL84 is nice linear in triode mode

Hi phildas

Some time ago I have been also interested in transformers' design and winding and I did some searching in the Web, but it is too difficult for me. Here are some links:

Transformers Part 1 - Beginners' Guide to Electronics

Building an output transdformer for a tube amp

Output transformer design and winding

Good luck

I reopen this old thread, sorry.
I would use the amplifier as the final so no potentiometer.
the idea is to connect it to Boz.
simply remove the potentiometer or the input must also mount some component (like a capacitor)?
thanks for any help.

If you know that the ECL86 is 1/2 ECC83 +one EL84 in a single envelope ...

No! It is half an ECC83 plus one EL41!

Best regards!
