Has anyboyd used this amp, your thoughts on it

The Glow One is a single-end tube amp using one 6BQ5/EL84 per channel at 3.5 watts output. Input/driver tube looks like a 12AT7. I have a similar custom-made amp like it using a 6BG6 pentode for about 7 watts and one 12AT7 driving both output tubes. Nothing new here. These simple circuits were used in table radio's in the 1950's. No feedback and at clipping 5% harmonic distortion.

Such low-power tube amps are better suited for headphones than speakers.

@jond : Since it has one output tube per channel it will of course stay entirely in Class A operation. Class AB requires a pair of tubes/transistors driven by a phase-splitter circuit.

The glow one looks interesting is that enough power to drive any speakers they’re going to have to be awfully efficient speakers. I was hoping something more in the 6w to 7w range.

Thanks for all your input appreciate everything it seems like a hard thing to fulfill what I want to g to get a good headphone amp and something that will drive speakers all in one package.

Not necessarily hard to accomplish. However it will require more expenditure to get a “good “ quality amplifier for your intended purposes. You’ll be hard pressed to get decent build quality, power supplies and output transformers at dirt cheap cost. Something has to give.
