DC wise its the same & works the same. You can check continuity
the same. If you know what freq it is designed for yes you could do it
that way. But the farther you go from that freq the more current it
draws & eventually it is seen as a short.......

Look at an amp. Output xfmr made to pass say 20h-20kh.
If you could get say 50kh through it the 6L6's wouldnt like
it & would glow cherry red & meltdown. Same idea. Go to
the secondary & it says "use 4-8-16 ohm spkrs". Use a 400 ohm spkr &
you barely hear it. Its not really ohms DC wise, but impedance. How things behave with AC & complex signals. Beyond that we get into engineering.
I wont go there, its better to look like a fool than prove it to all !!!

Oh yes, how the xfrm knows. its in the core material, windings,
spacing etc...........

Thanks Zeno and yes the EE part is mind-boggling tstl when you start getting into the formulars in the complex domain. Transformer lingo can get as hairy as you want to make it and I've seen and done a tad and it's not any fun but to an EE may be but I'm not one of those and don't want to be !!

I'll try to get to that site and see if those cats can help me out. TIA,

When you go to repair world remember they are mostly like us
making a living at it. So a quick intro is in order otherwise if you
say something wrong you will get bitch-slapped & many wont help
you.
Start the question from original problem & keep things in order &
simple.
And keep that tube stuff going, its all I will use for HiFi. Especially
appropriate since I got nothing but 50's records.....
Good luck & let us know what happens.

Your a class act Zeno thanks I'll let you know what happens. It will be Monday before I start as a busy weekend ahead.

Tubes are definitely the way to go and I'm also in a band and play guitar so yeah it's all tubes haha!

Class act ! Never been accused of that before.......
Give my parents the credit, not me.

BTW One other thing to keep alive. You used the term "cats"
I thought I was the only one using it left. Once my son had a few
pals over aged 18ish. I was chewing them out about something
( beer prob ) & said "you cats bla bla.... They were baffled &
laughed at me. Then one of them started insulting my Fisher
stereo tube amp. Not a good idea hooligan punk. I whipped out a mint DJ copy of Anisteen Allens " Fujiyama Mama" ( capitol 1955) & played it LOUD.
They were awe struck. Never heard audio like it.............
I guess I showed them cats !

I got an old Fisher SA300 that I put UL OT's in and it sounds awesome and just so unique and warm. The new gear has better quality and cleaner but the tone from those amps is stunning especially when you crank it . Glad you set those cats straight !!
