Opinions on Power Regenerators and Tube Amps

I use regenerated power on my sources for two reasons. 1- its too expensive too regenerate for my big amps. Also regenerators have limiters to protect them. So if your regenerator is rated at X then make sure your amp will never use more than 60-70% of X. I use a P-300 on my sources and could never do without it. If the power goes off and it resets its output to 60 HZ I can hear it right away. My setup loves the 120HZ setting. BUT don't buy a regenerator to try and solve your noise issue, buy one to make your system sound better. Tube amps will make a little noise audible from close to the speaker. Not audible while listening to music or in the listening position. My last point is that if you do regenerate it is better to start with the sources anyway and do the power amp last.

I love regeneration for sources and as I said wouldn't do it w/power amps. I reread your post. Do you get the hum through the spk w/ only the power amp on or when the pre is on and is set to phono? Thats a minimum of four gain stages if the latter and you will hear a little hum. Especially due to all gain needed for a phono cart. Back to your 120HZ question - it is wonderful and I have not met a piece of gear that can't handle it......unless you have an older TT w/ an AC motor that gets it speed calibration fron the AC frequency. As to N's comment on the lowish power output P-300(300 watts max, I never use but 60-70%of it as I said) it was made to drive sources not big amps. They had a 600watt and 1200watt for larger draw gear. Often a pre,phono,CDP and tuner wont draw but 100 to 200 watts total. In fact the process of turning the AC into DC, cleaning it and then turning it back into AC is what makes it so good. Then setting it to pulse 120 times/sec instead of 60.....well judge for yourself. Don't take our word for it, find a dealer that loans gear for home demo before you buy.
