Be well

In MIC preamps and PHONO preamps sometimes an input transformer is added
that bridges the mic/phono to the first stage preamp.

But many times it is done wothout any transformer , so what is the rule ?
When input transformer is needed and when not ?


** Tubes are not well suited to low impedance, low level signal sources -
cos they inherently have too much voltage noise.

Using a step up transformer changes that situation by boosting both the
impedance and signal level of the source to one better suited to tube
amplification.

There is no one simple rule about using such transformers as there are so
many different possible circumstances and applications.

What you have just posted is just another, meaning free dumb TROLL.

Why don't you get real - PAL - ask the ACTUAL question you REALLY
want to know about.

I will not hold my breath waiting for any anonymous fool like you to
respond.
