Ok. Transistor rectifier or Valve?
Follow Ups:
Ok Jedrider they are Valves but you can't help it. To satisfy Bromo's curiosity, yes its a diode and its a pre amp.
Well if you ever had a simple preamp with tube rectifier swapping will demonstrate quickly that it effects sound in a big way.
With SS upgrading to fast recovery types is a standard "mod" for obtaining better sounds, again obvious.
So I guess the answer is ... both. -;)
Fill me in on how good those BIG rectifier tubes? sound? Just curious. Seems like a waste of filament power to me ;-)
I'm interested in making a Turner 10 tube pre amp which uses Diodes as a rectifier but as i have done some research a lot of preamps use tubes as rectifiers.
I think it was 1947?It's an abbreviation for transfer resistor. It's intended use was for amplification, a solid state replacement for the triode tube.
You're confusing the issue when you say rectifier. That's the original Edison, or diode tube. It's not much good for anything other than DC power supplies - all very useful sometime before WWII.
Meaning that the modern replacement is exactly that, a diode - not a transfer resistor.
You're obviously of English heritage. We say tubes, not valves.
What was your question again?

I believe it would be more correct to call it a replacement for the pentode tube since it acts like a current version of one. The late VFET devices used by Sony in the 70s were triode like and voltage devices. They measured like a very good triode.
I went to college in the mid - 70's, we were probably the last group to study vacuum tubes as a lead-in to solid state. Ignitrons and thyratrons and all that.
Also, you mean DIODE and not Transistor (I hope)...

You can make a diode out of any transistor.
I used to do that as thermal compensation for power RF transistors.
The popcorn part 2907 on the bias circuit of an (ancient) MRF286 by Motorola kept bias +/-2% form -40C to +85C. Fantastic! :-D

As audiophiles, we take what's obsolete, make it beautiful, and keep it forever.
Hey! I have a blog now: http://mancave-stereo.blogspot.com or "like" us at https://www.facebook.com/mancave.stereo
True that you can make that! Been there, blown it up (just kidding!). Not so sure given the vagueness of the question and non-reply to my answer he is ready to make that leap! LOL

I suppose transistors should have been called 'Valvistors'. I'm glad we got to the naming before the British did this time around!
Now you're sounding like the musical instrument industry-
Valvestate.
Transtube...
