Thumbs up for ultrasonic record cleaning
@jtimothya Your example of particle size is unconvincing to me. A ’visible glop’ is made up of tiny particles which can be broken loose by US action, and then either deposited as solids or taken into solution as solutes, or perhaps even suspended.... 
Thumbs up for ultrasonic record cleaning
I also see that you are cleaning 6 records at a time, which means a spacing of at most 33mm. That spacing is OK for 80KHz, about 1.7 wavelengths, but, at less than a wavelength, that spacing is quite inadequate for 37KHz. Also, with 6 records your... 
Thumbs up for ultrasonic record cleaning
Thank you for the references, which mainly point out that there is very little formal research on US cleaning, beyond the obvious and the theoretical. Let me give you another reference: the Rushton thread (2016) here on Audiogon, to which I contri...

Correction: substitute "particles" for "gaps". Should read "For particles the size ..." 
Thumbs up for ultrasonic record cleaning
@jtimothya Don't see why a mixture of frequencies should be better. There was a graph posted in the DIYAudio thread of cleaning efficacy vs frequency. For gaps the size we see on records, 40KHz is only marginally superior for the largest gaps, and... 
Amplifiers weight
Two fans! Yikes!!  
Amplifiers weight
As noted, the size of the transformer is important. Inductors too, and heat sinks are heavy. The bigger the heat sink, the lower the operating temperature, for given heat dissipation.The amount of real estate inside the enclosure is also important... 
Which is the most important part of a stereo system?
@tweak1  Terry9, and anyone else who thinks cables are least important:you couldn’t be more wrong"So you think that cables are more important than the speakers? Amplifiers? Preamp? Phono? Turntable? Tonearm? Or cartridge?And what is your evidence?... 
MoFi - Are You Kidding Me?
Just got S&G's 'Bridge Over Troubled Water', limited edition. Flawless. Played my mint, rarely played original pressing, and it was no contest at all - MoFi all the way.Sorry you had a problem, but my experience was excellent. 
Which is the most important part of a stereo system?
Deschutes, why not DIY your electronics? I would say that the main thing is to stay away from teflon insulation, because when teflon heats up past about 450F, it begins to decompose into some really evil gasses. And unless you have a fume hood or ... 
Which is the most important part of a stereo system?
What @almarg said. I suggest not spending disproportionately on anything that (1) wears out, or (2) has low benefit per unit cost, like cables. 
confused and don't know what to do
COOL IT, why don't we?Right now the OP must be regretting asking his question. Let's show him a little respect, shall we? 
best phono stage under 10k
Always listen to Ralph (Atmasphere). I used his stuff before I went DIY, and it's very nicely designed and made. 
New Place - What Would You Do?
Room size has been investigated scientifically, and I can tell you that it works. I've built my own room to conform to scientifically determined specifications, 1/8" (3mm) tolerances, and it's the best room I've ever heard.Precise room dimensions ... 
confused and don't know what to do
Blades - haven’t heard them, but I entered high end by spending 80% of my budget on Magneplanar Tympani 1a speakers in 1973. The first speaker to be awarded Stereophile’s Class A.System didn’t quite sound like all mega-buck, but it was 90% of the ...
