Voltage conversion of Accuphase E-5000
@foolishman  The E-5000 has an auxiliary transformer that needs to be changed to accept 120VAC mains voltage. Main transformer voltage conversion is similar to the E-650 and E-600, just move the two plugs and sockets to the middle row.

The new Coda S5.5 amplifier: It's a "Petite Beast"!
@gryphongryph  It is impossible for a 50Wx2 pure Class A amplifier to only consume 90W at idle! The 90W reading must be in standby mode! The "BIAS" button should be turned on with no input signal to test idle power consumption.  
Accuphase E-260 Voltage Conversion (100V to 230V)
@jgore  The power switch is responsible for switching the mains voltage, unplugging the power cord when not in use will not help. If you want to avoid wear and tear on your power switch and minimize stress on  power supply components during the ... 
CAL alpha dac resistor values
I found a high res image on the web, looks like R102 is 22Ω (red, red, black) and R122 is 100Ω (brown, black, brown). However, the color code was quite different from the image which @dekay provided in the first post. https://post76.hk/th...

Only the 12AX7 are preamp tube, the 12AT7 are driver tube. If driver tube are not installed, the power amp will not work.

Unintended PC Comparison
To my surprise, there was ZERO loss of fidelity between the cables.  I thought how can this be so I started just testing the two PCs on both sets of amps.  I wanted to hear a difference.  I paid to hear a difference.  I heard ZERO difference.  An...

Power adapter/supply for Mirage LFX-3 crossover
I will opt for a 16VAC 1A rated Walmart. if you look at the schematic, the 4700uF filter cap is rated 25V which is a bit too low for 18VAC after rectified (18VAC X 1.414 - 1.4 = 24VDC), and the 7815 regulator only required 17V input voltage, anyth... 
Primaluna EVO 400 Amps/Preamp lacking bass impact
the only issue with using the RCA preamp out to the SUB, is the LFE is shared, so would have to unplug and change cables for movies. unless I am missing something. One solution is install a line level A/B switcher Or an Audio Activated Line-... 
Tube Amp recommendation for Thiel CS1.6 under $2k
The CS1.6 is not difficult to drive. However, its small woofer cannot be reproduce low bass. Twenty years ago I had been using an Audio Research SP-6C preamp with a D90 amp to drive the CS1.6 and a 15" subwoofer to enhance the low frequency respo...
