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.

I have to clean my system.

to clean the panel frontal metal and cover top I not use aggressive chemicals but only simple neutral soap three new and soft microfibre cloths, make two cloths damp with water, one must also have a little loose soap, run over the entire surface if it is level, rinse with the second cloth and dry with the last cloth.
If the dirt is stuck in the knobs and in places where it is inconvenient to pass the cloth just use ONLY a clean and new painter’s brush and dust.
To give an example: if the arm is very dusty, just pass a new painter's brush with soft fibers lightly dampened with water, then gently dry with a soft cloth
To clean the contacts you can use deoxidizing sprays, or isopropyl alcohol (in Italy where I live is in the pharmacy) DO NOT USE a alchool disinfectant, that is greasy and not good, use cotton swabs to pass every single contact.
to clean mobile speakers only dry microfibre cloth and dust

If you look on youtube you are looking for tutorials for all these little problems.
