MY VINTAGE AUDIO

Yes Susumu KS9450 and WE618B have the same dimensions,but can't have the same sounds and input -output impedance,and as with WE285L and another WE285 transformers they all very different.
Susumu I have problem to send to Russia tubes I buy on Yahoo,can you inquire about sending tubes to Russia by any post?

Normally, it would not be a munitions item, so we might be able to arrange an agency, but in the current situation, it may be a little difficult to send electrical parts to you.
This is the first time I see this site called In Japan.ru, is it a Russian site?
It seems that it is a scheme that can be delivered to Russia, but I do not know the details. I'm sorry.
The only thing in your transformers collection and mine is the T-30 and No.6600.
It seems that Kanno's transformer is still being used with great care.

It's amazing.
Did you take it all apart?

"InJapan" is intermediary company to buy from Yahoo ,but they told me the Japan banned many items to export from Japan, I can send this tubes to you if you can ship them tj me from Japan by yourself

I googled all this foto in the web

You are a dear audio friend and it is not your fault and I do not have any bad feelings towards you, but at the moment in my country your country is viewed very harshly. and it is unlikely that your request will be answered. I'm sorry.
