OK, since there
seem to be a fair amount of people into Tube audio,
or at least with a knowledge of it. Would someone care to explain
the following to someone that is used to an all in one unit such as a
Sony Receiver. What is the purpose of separate Amp and Pre-Amps. I
think I understand the whole phono pre-stage, but I've yet to find a
decent explanation of the rest, and I'm looking to switch to tubes
for playback of records (primarily Vinyl, but I'm also interested in
78's).
Purely from memory, but I believe one generally used a separate pre-amp
mostly due to hum issues. The power supply for the preamp could make use
of lower plate voltages, better regulation and DC heater supplies.
Or so I think I recall.
