For sale is this 10W Stereo monoblock HiFi vacuum tube amp with 8 tubes, and lets you plug in 6V6 6L6 or 2A3 tubes! About 10 watts, or 5 watts/channel and switch between stereo 3.5mm(1/8) input and RCA inputs, and outputs for 4-8 ohm speakers. Plenty of gain or an iPhone6. You get your choice stereo 1/8 (3.5mm) plug to plug cable, or RCA plug to RCA plug cable free. Let us know what cable you want.We also have cable for iPhone 7-10 but didn't try that yet. Uses a new Tung Sol 12AX7 pair(included), and for outputs you can plug in. A 6V6GT pair (you get a NOS pair). Or a 6L6/5881/6L6WGC pair (you get a new 6L6WGC pair).
Or the 2A3 pair (you get NIB pair). (you also can plug in a 6B4 which is a octal 6V heater equivalent of 2A3).The secret to the great sound (besides hi-fi single ended outputs), is 3 million uF of filter capacitors. If you ever tried an AC filament 2A3 amp with hum adjust, you can adjust out the h um at zero volume, but crank up the amp and quickly turn down the volume, the filaments sag a little under load, youll hear hum till the 2A3 cools down again. This amp is all filtered DC to filaments and autobias, nothing to adjust on the 2A3s or pentodes, and heres the noise specs. We tried amp and minimum volume, and max volume plugged into an iphone with video on pause. With the new 2A3s you get noise always measured 0.000 mV on both channels.
With the new 6L6WGCs you get, noise always measured 0.000 or 0.001 mV. With loud music, you could crank over 5000 mV across the speakers.
You get 8 matched tubes, but if you use your own tubes, only the 2A3s have to be fairly matched because their 2.5V filaments run in series from an ultra filtered DC supply. If you want to run 6B4s, we recommend the 1973-74 type that look like 6L6GCs. Ncludes diagram, and has metal bottom, runs on 115-125V only. Note- not made to run 2A3s and pentodes at the same time. If you accidently run all 4 output tubes like the picture for a few minutes, it won't hurt it, but for continuous use, use only 1 type of (pair of) output tubes.The item "10W Stereo monoblock HiFi vacuum tube amp plug in 6V6 6L6 or 2A3 tubes" is in sale since Sunday, August 4, 2019.
