#theaudiovoice 521: A New Op-Amp for Phono Preamps. In this article, Brian Lowe (Belleson) details how he developed a unique custom transconductance amplifier (Bel Amp) with fully differential (balanced) low noise JFET inputs and current output for phono preamps.

you could also directly measure the transconductance with modern test equipment. the circuit setup shouldn't be too difficult

"That'll be your classic poly800 problem with the transconductance on the coaxial flange modulator. Just tell them to use shielded cable when connecting up the internal binary bandwidth encoding capacitor and it should be ok."

Okay, here’s 22, by my count: transconductance amps are really cool and underappreciated outside synthesis builders. Think like an op amp except for current instead of voltage, and also they can multiply a reference current; the LM13700 is I think the only one still currently made.

Did you ever read his paper on Thermionic Transconductance?

Gotta love Picard's use of the Finger....and a good timing for him to get out of a conversation with a Bolian, they always are a Talkative lot.

lemme guess...you also have not yet read his paper on thermionic transconductance?

I feel sorry for the little fellas, but where else am I supposed to get a transconductance amplifier?
February 27, 2026 at 8:01 PM
something similar happened recently with a bjt transconductance formula

like it's weird to feel "i must be so old to have forgotten this"

and also "i am old in a way that i am capable of learning things with more rigor and depth than i used to"

at the same time

Output tubes have a lot less transconductance than a mosfet. You can reduce transconductance by adding a source resistor. You need to get rid of a lot of heat which I'm assuming that black shell does. So basically just a heat sink and a mosfet and a resistor maybe a diode to simulate grid current.

I'm a big fan of lateral n and p channel enhancement MOSFETs. lower Cgs and Cgd than the equivalent VFETs, albeit at higher Rds. They go faster for a given drive current, and have the advantage of a negative transconductance temperature coefficient, so they're practically indestructible.

Not just matching on the outside, but matching on the inside at 3% diff for transconductance and both over 100% nominal. They’ve been hiding in these boxes longer than I’ve been alive. Should make somebody happy soon… #audio #tubes #nerd
