@ bill

why is it catorgized 1 .0000 ... prue if there is no higher grade...

it is an aloy ... but it is not magnetic .. and we cut right through ...  colour does not change ...

it has me bugged ....   i donk know crap bout gold ...  it looks brighter than my ring and it is 10 k

someone has to know!

why would they use it on the input and output ...

all eq pins are gold coloured too looks to be the same material ...

cant find crap all on the net bout a 3 crown ...... so ...   makes me wonder ... IT AINT LIKE THEY NEVER MADE EM ...   i have many i took apart

serches turn up next to nuttin ... y?

there a trained rf engineer in da house ?

i have this exact unit ..  this is what the maker of them say ...

ISt take them to a metal recycler and let him extract the gold . It involves acids ,electricity boron and other dangerious chemicals . . He will know the content , Also a pawn shop can acid test a piece for you but a recycler that has a laser spetigraph can tell you what is is and what alloy content vers gold ,latnium what every . they do it all the time here to test old watches , catalitics ,you name it . It is 100 % accurate .

i have a sample at dc tailer julers .. they have the tool .... but they WONT TELL US WHAT IT IS !!!!!!!!!!!


Y?

WHY IS THERE 0 INFO ONLINE ? bout this stuff



ist!

im not worried bout it in the least this is odd why i cant find crap out bout it ...  i have tones of silver it is worth something too ... and it can not be mistaken ... lol

basically they are hitting higher frequencies than us and in order to be able to handle it and not reduce the frequency with mechanical parts that cannot handle it they are using specialized ion transistors and gold which reduces resistance and losses. its expensive stuff and good. play with those transistors and some air cores, bet you will get some crazy frequencies.

ist,
It is just that you do not know what to look for.

I don't get it.
I told you how the alchemists find out if they made gold or something else.
It is the specific gravity.
There is nothing that weighs the same amount as gold.
And a stack of pennies the same physical size as the sticks you showed us will be less than half the weight of the sticks.
Your job is to make the sticks line up and fill the same amount of space.

You need a penny coin tube so the diameter is right.
Then keep forcing the sticks into the paper tube til it is full.
Then make a stack of actual pennies with the same dimensions.

Now weigh them.
If they weigh the same you have copper or nickel that is gold plated.

If it is double the weight you have pure gold.

If it is more than that you ave platinum gold alloy.

It is worth the trouble to make the stack just right so you can see.

edit
From what you have described these amps are quite old.
If they were made during the beginning audiophile days when gold cost $35 per ounce, it could have been made from pure gold.
[My vague memory tells me the gold price went open in the early 70's but I do not remember it going high until 1976 or thereabouts.] - vague memory.

this is more complicated but you can use this too
