6J2 Tube Buffer 0.85 times magnification, connected between the source and before or after class, can effectively filter digital flavor. 1, AC 12V input: The DC3.5 / 5.5 * 2.1 socket, 12V AC power adapter, if you use non-plug AC 12V transformer, power cord need to solder on the circui...
The amplifier front end uses a dual op amp for audio amplification, and then drives four dual op amps as buffer level outputs. The output current is multiplied, which solves the problem that the output current of the preamplifier is small, so that the preamplifier can reach the output ...

I should emphasize that I amnotarguing that a passive preamp costing several hundred dollars is a proper substitute for an active preamp costing several thousand. Quite aside from the issue of giving up a phono stage and the need to buffer tape recorders, I have never yet been able to hook...
The business end of the device has a single differential gain stage with an output stage buffer with zero feedback. Four sets each of balanced (XLR) and single-ended (RCA) inputs are fitted, two pairs of balanced and single-ended outputs, a separate record output and an RS232 interface ...
settings. It's extra quiet because its special gain control circuitry means that it rarely needs to apply any gain at all; it's usually working only as a buffer as opposed to most preamplifiers, which always need to be operating at significant gain, regardless of the volume control setting...

(VGT) circuit adjusts volume not by throwing away varying amounts of gain but by adjusting, at its source, how much gain is created. Its active output buffer is based on Ayre's "diamond circuit" arrangement of bipolar transistors. And its AyreLock approach to voltage regulation creates, in...
