Hello!
Finally I have found 6AN8, but in Canada, not in Russia. Waiting the parcel at the moment ))
Now I'd like to know your opinion about resistors.I see many good feedbacks about old Allen Bradley resistors. Do you recommend them too?
Or resistor does not have any musicality but only value in Ohms?
And the last: do you remember my question about free wire of my power transformers?
Two transformers (a step-down 230/117V + original 117V) aren't good for sound quality therefore I hope that the free wire is intended for direct connection with 230V power socket. Is it real to find an information about transformer's terminal and what does each color of wire mean? The signs on transformer are:
1. Dynaco
454216
ZT0195
74-46
2. 494203
11713
Coul you suggest somethig?
Anyway I'm the one who ought to thank you.

The differences in sound quality among different resistors is more subtle than other things like capacitors. Here is a discussion that might be of interest: resistor discussion
If the original resistors measure within tolerance, they should work fine.
For your power transformer, I was not able to find any documentation on it. I'd like to say it is as simple as swapping the wires (which might really be the case), but I don't want to tell you the wrong thing. You might try posting in some other forums like Audiokarma or tubes4hifi. Someone might know with more certainty. You might try e-mailing Dave Gillespie who frequents Audiokarma - he is a Dynaco expert.
I'll try to use this approach: I have an autotransformer and increasing an input alternative voltage from 0 Volts on a vacant black-white wire I'll try to measure a voltage on the rectifier tube (pin 4-6). Very carefully ))
That sounds like a fine idea. You could also temporarily connect the wires in question to a temporary terminal strip and then just measure the voltages between them as you turn the mains voltage up gradually.
Thanks again and my best recommendation!
