Having just built one of the 6J1 preamps is was not expecting to get much more than some fun with tubes. I took my time with assembly checking connections, testing point to point and power testing no tubes just a load resistor on B+. First I did not have a 12VAC wart on hand but I have a 8.5VAC good for low power testing. Upon connecting to a OGG source and output to a Fosi V3 I was floored. Bass, High and Mids was great, I did not detect any hum. Pushing the gain a little more than needed I did start to pick up distortion. More than likely at 8.5V instead of 12V I was just running out of headroom. The people that designed these hobby amps really did their homework.
I hope I am on the right page. UA-cam has changed the way accounts are named and addressed. But if I am on the right page, just wanted to let you know I am playing your Rally-X clone and its great. Congratulations on creating it. Hope you do more.
I appreciate your great video and measurements. For audioholic however, more important is HOW IT SOUND rather than what numbers it has. so please describe HOW IT SOUNDS comparing to 4k amp?
Interesting, but a slight correction: you misspelled the other review source. It should be spelled Stereopile. They also seemed to make a mistake, since all Audiopiles know that the highest priced amplifier is best! Perhaps they could have gotten better test results if they had used the correct cables, each made of 3200 fine strands of individually cotton wrapped Litz wire braided in the pattern of a unicorn's tail to interconnect the amplifier. Also, the amplifier itself should have been placed on a one meter Marble cube with little Titanium spikey feet resting on a polished granite floor for optimal performance.
Thank you, Jake! It seems there’s virtue in the simplicity of tube circuits and low part count.
Amazing videos, thank you for sharing what small changes can do. 🙏

Thanks.Can you measure this budget preamp by Audio Analyzer Suite?
Just goes to show, some will exploit those willing to throw their money away on perceived quality because of price based expectations and looks. Lols.
