I decided to risk it, Russian, no return. (he accepted my $400. offer, so $500. delivered).

Gives me tubes in my office system.

I just read something:

People don’t want advice, just confirmation

I’m not looking for either (this time), just thought some of you would find it funny and wish me luck.

I’m 72, it may arrive before my 75th birthday

Here is a useful website: https://www.radiomuseum.org/tubes/tube_6n4p.html
From that page, you can also look up the 12AY7 and 6072.  To my eyes, the latter two should be cross-compatible with the 6N4P. (Be careful if you do your own research, because apparently there is also a Chinese 6N4P, and it is not the same as this Russian 6N4P.)  The caveat is the filament voltage.  For the 6072/12AY7, they can be run on either 6V or 12V filament supplies.  I am not sure from the information on the given website that the same is true of the 6N4P, which may require 6V.  Still, I don't see why he says you cannot use the 6072/12AY7.  The pin connections to plates, grids, and cathodes are identical to those of the 6N4P, and the electrical parameters are close enough. Ask the seller.

chakster, anyone?

Seller accepted my full refund request, but say's unable to send me a pre-paid return label.

Who knows the Easiest, Safest, Least Costly way to ship a package from USA to Russia?

I have his shipping box, will weigh and measure it, then I'll tell the seller the cost, they can send me that amount via PayPal.
Ship with USPS Priority Mail and he will get it in 30 days (or faster). Calculate exact shipping cost at your post office and ask him to cover it (you can send postal receipt).

If you want to pay more you can ship with USPS Express (and he will get it in Russia from EMS (courier delivery), it can be delivered in 2 weeks or 1 month.


If you will declare more than $200 he will pay import tax, so it’s better to declare no more than $200 in your custom declaration (no import tax for him).
