Made an account here purely so I could ask you what model transformers you used. I have a transformer box I built and enjoy greatly, and...

Welcome to the forum! They are Lundahl LL9202 transformers. All sine wave measurements posted are of the transformer setup. Of...

Thanks to @Aokman for his inspiration and advice, along with @kevin gilmore for answering questions. This setup sounds fantastic...

Back in 2019, I reviewed the Benchmark AHB2 Stereo Amplifier. I received a second sample from a kind member to update the measurements...

It has a tube amp, that is for sure. But does it really has audible distortion?

Fair enough, thought I saw someone who managed hit it but I didn’t look closely so probably wrong :) Those Edcor transformers really...

at no audio frequency can the eha5 generate 700vrms without the amp going into shutdown mode. bob katz and others have tested this. the...

It’s all a clusterf to be honest, especially as measuring such audio performance at such voltages is tricky / no industry standard of...

Not slimy at all IMHO. Any technician or engineer understands rms vs peak to peak vs peak, and it clearly states peak to peak and not...

1600 volts peak to peak measured stator to stator is 571 volts rms measured stator to stator. electrostatic headphones are a balanced...

The highest the L+ wave can be wrt ground is limited to A = 400V (actually it's a little less than that). Now, since L- (dashed...

Hunt down someone to make you a proper transformer box for the less money or go DIY if you’re capable. The iESL definitely isn’t worth...

I'm pretty sure they're all like that due to math :D But yeah, it confused me for a bit before I drew out the waveform... If you...

koss measured single stator to ground. stator to stator gives lower numbers, but i need to build attenuator to get to 700rms...

That's the goal I guess... The general pattern seems to be 1) Amir posts some controversial measurements. 2) knowledgeable members...
