Brand New State of the Art Phase Inverter Design

I've been putting in a lot of hours into this design and have finally finished a prototype differential amplifier design with successful simulation. I've created a brand new differential amplifier that has better than 0.5ms settling time swinging over 170Vpp!!

What does this mean?

My design will produce a better low end response, better top end detail, all while providing better vacuum tube life. Your effects loop tone won't degrade and you won't need to worry about tone suck from effects loops in your amplifier anymore. This all stops with Radiotron Engineering :rock:

The current standard long tail pair that exists in every guitar amplifier in existence since the 1950's that utilizes vacuum tubes hasn't changed one bit. Everyone overlooks this critical part of a guitar amplifier due to its complexity and ability to be just good enough. But as high gain amplifiers continue to demand more of vacuum tubes and effects continue to get increasingly complex, this is a critical stage I found needed immediate resolution.

Here's a simulation of a 50W EL34 Class A/B amplifier utilizing a standard long tail pair design:

Very interesting.

Will you patent the idea?

Look forward to hearing it!

Thanks man :cheers:

Most likely yes 👍 assuming everything works out.

I just need to build it to test it out now.

I have another version of this one I’m working on too - believe it or not there’s more performance on the table. Stay tuned as there’s more to come :rock:

These designs I’ve created are so much more efficient that it’s a total game changer. If this works and the version after it as well, you’ll have to dump the bias on your vacuum tubes to basically off with no signal because you’ll need the extra peak to peak headroom to take advantage of the insane gain of the phase inverter. What this means is chest thumping insane attack and low end like absolutely nothing else as you’ll be changing from class B basically off to class A/B fully on dynamically as you play which is really cool :rock:

This sounds great. As does your gate idea. Plus, i need to try that prototype amp u are working on. Where you located?
