Hello all,
I ordered Edcor WSM600/15k which is a tube preamp input transformer by mistake instead of WSM15k/600 for a DI box project.
Can I connect it backwards as an output device?
If so do I need to do some compensations?
Thank you

What tube and operating point, i.e voltage and current, do you plan on using with this transformer?
If the frequency response is suitable for your project, you may substitute it in reverse as you noted, however, the biggest factor is going to be the current handling capability of the primary winding of the WSM15k. If the WSM600 cannot handle the same current in the secondary, you can always connect it in a parafeed configuration to eliminate standing DC.
Hi,
Thanks for the reply.
It will be connected in the output of a 12au7 white cathode follower with a coupling capacitor so no DC in the opt transformer.

Got it - scroll down to White Cathode Follower Power Buffer configuration.

A plate choke is not strictly necessary - you can use a CCS (tube, solid state, or hybrid) rated for the B+ voltage that will provide the specified circuit current at a much higher impedance than a choke can provide.
For the nuances of calculating plate choke parameters, do a search of the forum.
