The lead free solders really messed with the sound for a while. It seems they have some better formulas now. I still have a couple of 1 pound rolls of high quality lead solder but I understand the need to change. Yes, I do use some oil caps and they are available now. You can get aluminum and...

It is about tone, or a least that is a big part of it. Yes the metals were different and they worked on it like it was an art, as we have mentioned. Using carbon resistors instead of metal film, though the carbons then, weren't always stable, they had a warmer sound and personality, if you will...

Truly pure silver is dead soft and doesn't get brittle. In fact true pure silver goes dead soft, which is what you want anyway, for the best sound. I use only 99.9995 or greater purity silver. Yes, there are some fun materials to use in transformers and expensive but good iron or iron and nickel...

The primary doesn't need to be silver and the secondary can be a copper/silver mix, so much money can be saved but you get great results.

I am referring to the wire used in the windings.

I never said that which is used wasn't good. I merely stated that a silver secondary can be extremely fine. And I never said other manufactures did not understand the art, though some do not. A silver/copper is also used for the secondary with very good success. Electraprint transformers are...

There are many on Ebay. Millions of the 6n1p were made so what you see is rebranded from stock NOS in Russia. Early versions, before 1970 are almost nonexistent.

The iron does it. You can change tubes and modify the circuit but without good iron . . . Transformers are almost an art. I would love to hear an impression of an output trans with the secondary in silver in one of your amps. There really is a boost to sound with the silver as well as cost...

The build won't tell you how much voltage. I was hoping the manual would have a schematic. No matter though. If it sounds good then all should be fine. If a 6DJ8 type can not be used in the circuit then it must be running at the higher voltage that 6n1p's like.

Does anyone know the plate voltage being applied to the 6N1P in your arrangement. The 1965 can take the voltage and steps up much better than often mentioned 6DJ8 family when it is run at voltage that the 6DJ8 types can't handle. It does not open up at lower voltages. It can also be interesting...

Not the same tube. Those are later than the 1965 and based on digital technology. The 1965 black plate triple mica were for military use in tanks and planes. The later uses were in digital circuitry and have a different plate and design and sound to them. The 1965 are true analogue tubes for...
