Voltage conversion of Accuphase E-650
@systemroot  Thanks! I'm just a HiFi hobbyist, Not a specialist at all🙂! Sorry I don't have any experience for voltage conversion of Dp900 or DC901. However, some Accuphase CD player utilize low power transformer with jumper setting, J1 for 100V... 
Threshold T-200. Help me choose a preamplifier
NT-505 XLR → Jeff Rowland balanced preamp → Threshold amplifier (RCA input) - there is sound - This connection worries me a lot. It depends on the Threshold amplifier input circuit design, some amplifier just simply use a spst switch to connect...

Seriously though, not grounding the chassis of a high voltage component is hobbyist level BS.   Class II electronics    
Owners of Carver Crimson 275 -Caution/Warning--Potential Increased Risk of Electric Shock
would a GCFI outlet/plug truly make the unit safe? Same as a fuel cut off switch that shuts off the power supply for the fuel pump if the vehicle is in a collision. Thus, it prevents fuel from being pumped in case of fuel line damage during an ... 
Broken Tube Guide Key
6SN7? The filament pins of 6sn7 are 7 and 8, you can use a DMM ( digital multimeter ) to identify the filament pins by using ohm meter, other pins will show open circuit except pin 7 and pin 8 have resistance reading.    
Balanced vs RCA between amp/preamp
@runwell  Just curious what RCA pre and XLR power amp connected via ISO MAX transformer?  
Underpowered?
Another aspect of this is that the issue doesn’t resolve with high volume, which yes, comes with a better bass response but at levels where the highs are too piercing and fatiguing. The amp and speakers ARE capable of getting to good bass levels,...

It is quick-disconnect terminal.  
Audio Research Refernce 75se
My friend own a ARC ref 75se for many years and doesn't experience any hum/buzzing noise from its transformer. Transformer hum/buzzing could be due to DC offset in AC mains, or the transformer loosen itself from the chassis, both can be easily fi... 
Jadis DA-7 fuse?
 Usually fuse size is stamped on its end cap, always replace with same size for proper protection.        
Connecting a Conrad Johnson premier 16 v2 to a Marantz home theater sound processor
I think the CJ premier 16 doesn’t feature HT passthrough, what you can do is connect the Marantz processor front left/right output to premier 16 one of the line input via RCA cables, set the volume level to a fix number like 65 or 66 (unity gain) ... 
Accuphase E600 voltage conversion
I think E470 has different layout, if you can post a picture of the voltage selection board, maybe I can provide some help on the voltage conversion.
