Berlant 20/20 Preamp Transformer Question

[iamflipper]

Very new to this place! I usually just play around with guitar pedals, but recently got this preamp and wanted to get it set up to run into my interface.
I don't want to change anything inside the amp if I can get away with it, so my question is this:

Can I use something like the Jensen JT-115K-E

Or the Cinemag CM-2511

And wire those into an octal plug for the input transformer on this preamp?

If either of these would be suitable, I'm lost on what wires go to what pins...
Again very new to Tubes and Transformers but would love to dip my toes.

Here is a schematic and wiring diagram of the amp on page 30

One more thing, the previous owner used a Jensen JT-DB-E on the output transformer, will that work out alright or should I find a replacement?

If anyone could point me in the right direction that would be awesome! Thanks!

yeah looks good--there are octal 1:10 or similar mic transformers out there---they may require a re-wire of the socket. can't go wrong with the jensens.
does the bridging input work-pass signal?

Thanks for the reply! it does pass signal. I was looking at some mic transformers that are octal but wanted to steer away from rewiring the sockets if I could, I want to keep it as original as possible I guess, but rewiring it back wouldn't be bad if I ever needed to! But I think the Jensen is what I'm leaning towards most, just don't know how to wire it properly lol.
Thanks again for the response!
