Or, at they weren't prior to the arrival of the PS-Tube power-supply, as this PCB contains a voltage-doubler circuit for the heater power supply and a tube-rectified center-tapped full-wave power supply for the B voltage... (I started to write sister PCB, but the 5Y3 tube rectifier made me change my mind.Sometimes a cigar is just a 5Y3, but not this time.) Where the PS-Tube-SS was designed for those who wish to build a tube power amplifier, the PS-Tube was designed for those who wish to build a tube-based line stage or phono stage—using a tube-rectifier-based power supply...In addition, each channel's heater power supply connections are separate.And the new PCB is half an inch shorter (10.5 inches long).These young babes are all eager to explore and get dirty, so you should feel lucky to know that all of their hardcore antics can be found in one place; our movie gallery. The lusty and dirtiest teenage bimbos all end up in our daily stream as part of our ever growing porn collection!— Since 1999 — Welcome to over 50 articles on amplifiers, tube-based preamps, crossovers, headphone amplifiers, single-ended amplifiers, push-pull amplifiers, Circlotron circuit design, hybrid amplifiers, cascode circuits, White cathode followers, grounded-cathode amplifiers, tube series regulators and shunt regulators, the Aikido amplifier, tranformer coupling, DACs and tubes — and hundreds of vacuum tube circuits that use 6SN7s to New CCDA Mono Noval PCB In post 459, I wrote about my urge to build a truly minimalist line-stage amplifier, which would take advantage of my PS-21 power supply that offers a regulated high-voltage and two entirely separate low-voltage outputs.

In contrast, I have met many tube fanciers who have only owned noval-based audio gear and have shied away from octals due the high prices of NOS 6SN7 tubes...Glass Ware Product: Triad B Transformer The Triad VPT230-110 toroidal transformer holds two secondaries and two primaries...Select-CM You already know that the standard Select-C switch allows you to switch between output coupling capacitors—in stereo. In other words, this is a special capacitor selector switch that is designed to work within dual-mono setups, either line-stage or power amplifiers.This power supply is super simple: two 50µF/550V polypropylene capacitors, with a power RC resistor in between, and a tube rectifier.This new power supply is quite similar to the old PS-5.
