Need help to know the value of these items

Elliot lewm, thank you for tips. Im looking and searching searching for those tubes amplifiers the Russ L. Can’t find any info about then. Elliot never listened the system works. I’m scare connect the elements and make some wrong connection and damage some parts ( tubes). 
Found about the Tango’s transformers... is a shishido 2A3 amp. Made by a UK company.
This inheritage is a long funny story.
Cesar.

Never heard of any audio product from a company called "Russ L".  Are you sure it's not "Russell" or similar, with a few letters wiped away?  Even under the name Russell, it rings no bell with me.  However, a Shishido 2A3 amplifier with Tango transformers sounds good, if the speakers are efficient enough.  Can you post a photo?

The SkyFi Audio, told me the Russ L maybe is a home made equipment with good parts. The speakers are a model 7 electrostatic speakers from the Dutch company Final Audio. I thing I have 2 monoblocks tubes for amp the speakers... 
The big problem that I have is wire the components... my brother in law gave me all disconnect... and he forgot to take picture of how the system were connected. 
I have the Michell ISO phone stage for MC cartridges and a Michell Hera psu...
how do I post a photo??

how do I post a photo??

you can use postimage is free https://postimages.org/

upload one photo at a time from your pc or tablet or notebook and when you load it, a window opens with different options, you will use the second option starting from the top
copy it and paste it into your post ... if you have multiple photos, repeat the same procedure

this is my Tabriz for example, check if yours is equal from the counterweight on the back.
