The transformers will be a bit more difficult. If you can identify the windings by color code, you can make an educated guess, given you know enough about electrical theory and searching for old transformer manuals. Those can be tested by applying a variac with in line fuse to the primary and measuring the outputs.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
Audio Transformer creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. The primary and secondary winding turns ratio fixed to 1:1. Due to this, the transformer does not alter the voltage or current level. It does only create isolation between the Input amplifiers with the output speaker system.

Need Help Identifying a Transformer
https://antiqueradios.com/forums//viewtopic.php?t=408480
From the way it is marked and size , it appears to be an audio output transformer for a single ended tube amp .If you have an audio generator and a scope (or a wide band AC volt meter ) you can measure the frequency response . From its size it is for a 2A3 or 300B tube most likely but could be used with a 6L6 . _____

Nov 20, 2009. #4. To go a bit beyond studiot's post, an audio transformer will often have the primary and secondary resistance listed. Something like 8,000 ohms and 300 ohms, for example. A power audio transformer will have the power handling listed, and then something like 1000 ohms and 4/8/16 ohms, meaning the secondary is tapped to match the ...
Identifying Power Transformer Windings
https://www.radioremembered.org/xfmr.htm
On a transformer where the color code has faded to the point as to be unreadable, here is a method to identify the various windings. The ohm-meter is the test instrument we use to accomplish this. As can be seen from the diagram, each winding will have continuity from one lead of the winding to the other, but there should be no continuity ...
Valve Amps: Output transformers - Lenard Audio
https://education.lenardaudio.com/en/14_valve_amps_5.html
Transformer winding is an extension of the fitting and turning industry. Few people working in transformer winding companies have a knowledge of electronics or valve amps. Most valve amp manufacturers have a basic academic understanding of output trannys, but often have a limited or incorrect understanding of the physics of transformers or how ...

https://openaccess.thecvf.com/content/ACCV2020/papers/Lin_Audiovisual_Transformer_with_Instance_Attention_for_Audio-Visual_Event_Localization_ACCV_2020_paper.pdf
Audio-visual event localization requires one to identify the event label across video frames by jointly observing visual and audio in-formation. To address this task, we propose a deep learning framework of cross-modality co-attention for video event localization. Our proposed audiovisual transformer (AV-transformer) is able to exploit intra and

Some transformer winding Houses offer a ' Detail Rewind service ' where they strip the core out and wind exactly the same windings with the same number of turns and wire sizes .This can cost a little more and may be worth it .Otherwise you can look at the big electro caps and multiply the volts by say .7 and use lab supplies to slowly crank up ...
