The Amp Garage

When I really open the volume I moderate all tone controls very slightly. I am most often using G12/75's. Early eq setups need more attention that late eq circuits when changing overall volume. It might be interesting to build an Express with TS after stage 2, kill about 12dB after input stage and u...

It sounds fun and you subverted the soul of Liverpool. Congrats lol

I changed that 150K to 33K, and changed gNFB resistor from 100K to 50K. Still way too bright. I'll have to spend more time tweaking. What are you playing into it? You should try 68k. That is what was intended. The coupler is too small to make meat, but with all that gain.. I actually use the 100p b...

Hey Aaron, I just built my Liverpool for the second time. I used the 68k instead of the 150k per Miles suggestion. Mine has the high gain hiss but No extra noise. I also can crank the amp to 2 than after that it’s way too loud. I guess these amps are like the express as a lot of the volume comes on...

Where did you end up on the third stage? I have no idea why the hell a 150k would be suggested other than joking about sustain and getting 100w peak transients out of a 35w amp. The high end response on my amp taps the stops on my meter. My 60w amps don't. Red light scares me. Do you know the Scorpi...

Build finished, fired up successfully. 316v plates – 10.3 cathode = 306v plate-to-cathode, 10.3v across 130R cathode resistor = 80mA, or almost exactly 100% dissipation, so that's nice. I have a LOT of noise at idle. It's not the gNFB, it's just a huge amount of gain following the Volume pot. If I ...

Oh man! I just realized where we need to look.

Doug Fearn. If anyone has more than simple insight into everything and everything else, it is him. His mic amps are mostly RCA tube manual designs at the core.

He picks parts for a real reason. There aren't many parts.

Frequencies above audible range do affect the outcome... I recall hearing R. Neave say (in an interview) that he thought mixer amps needed 100k BW, even though that wasn't generally accepted. This is where the virtual space of the machine is. In a couple very nicely equipped rooms I have sat with s...

For impatient people who don't like mislabeling agenda as content. I mean old people.

It is a radio show. Don't try to watch it.

Same reasons, everything. Me too.

Shhh.. don't tell anyone I said your amps are better than.l umm.. other amps. "other amps"..

Sorry I somehow miss this everytime.

The Jose setup does change things a bit. It makes the amp more muscular when the Jose volume is moderated to about 7. Nice highs. No more trash.

Add a simple master and also moderate to about 7.. in fact, set everything at 7. Always.

Frequencies above audible range do affect the outcome. Imagine if you had an eq setup for an arbitrary range above audible say.. 40-100kHz. Phase shift. It's a thing. Dmn it is hard to talk about this without woo-woo words. The.. magical virtual space a machine makes (that I mentioned earlier) is as...

It's only a couple hundred volts.

Ok, I see you do things differently from me. Is there a video of you mining the ore you smelt your chassis from?

And it looks great.

Losing the click is the key, and it is done by exposing only the barest sliver of the pick and muting only that duration with the thumb and index finger. The smaller the point.. time on the string means noise. Many people would look very hard to see the exposed point when I hold a pick. It is not mu...

I have the profile. Nothing else matters... except for coffee.
