As opposed to Head-Fi, where we ALL always agree on everything!

It's not about differing viewpoints (which is a good and healthy thing), but rather about some people's inability to tolerate a viewpoint that differs from their own. I feel like the silos we live in have grown very tall in recent years.

Indeed!

Yeah, the whole "I disagree with you, therefore I hate you" thing is getting old in general. Who knows, maybe my project will get a warm response, I've been asked by many people on diyAudio for access to schematics / BOM etc. for personal projects I've posted there. I've been surprised before too, I've posted several projects on ASR, the one that got the most praise was my tube DAC which I was certain would cause the most offense lol.

I finally got my hands on some 6550, won these at auction, NIB for $180.



I'm reeling from four crazy work shifts, have today and tomorrow off, gotta figure out what steps to take next on the pentode amp.

My DIY audio racks, solid cherry and patinated copper. I built the new rack in one day, filled it in about 15 minutes. Routing all cables will take a while. I may eventually adjust shelf heights but that is easily done.

 

[jgwtriode]

Very nicely made! Impressive

At long last my Rebuilt DAC has been shipped! Should be here Friday...and in about two weeks...fully burned I should really be able to hear what the Airmid is capable of. Can hardly wait. Will be resetting up and reconfiguring my system this weekend. What a wait it has been.

Happy listening,

I am getting back into vinyl and after many years of buying collections it is time to give the records a proper cleaning and dispose of any that are not up to par.

Finally! Let us know how the DAC turned out

 

[jgwtriode]

Yup I will....and how it sound with the Airmid. Should be pretty nice. It's running with A JCat USB XE in front of it on a Super Cap Supply, Wywires Diamond connecting it. And the Airmid has Wywires Platinum Power Cord and Interconnects feeding it. Should really sound pretty damn good! Ric says it sound quite a bit better than stock
Gustard X26 Pro.

Very nice! I remember using my Nitty Gritty Religiously back in the day. Before ever playing, carefully removing the record from the sleeve, precleaning with a Blue soft velour/felt pad (don't remember the name). Then the wetting process , bought the expensive fluids; then learned to make my own from a couple of recipes. Made it by the Gallon. Soaked the record with another soft foam brush. Then ran the Vacuum., one side at a time. I had the manual Nitty Gritty, which worked just fine. Before I ever played a record I LASTed it and put in custom,, soft, clear vinyl/rice paper sleeves I bought. to replace the crap paper sleeves record usually came in. And then carefully positioned a Golden Last sticker on the album cover. I would always clean the record before playing it. And of course always clean the stylus on my cartridge before playing. Ah the "Ceremonial Purifying Ritual of Listening to Vinyl"!

Happy listening,

Yes indeed! I actually thought Ric might Carc it. He is 82 years old. He has been modding for Decades. LOL.

Here are some quick and dirty measurements of the pentode headamp this morning (I swear I will try to come up with a name by this weekend, I have been swamped at work!). These are of the right channel using Philips GZ34, Tung-Sol 6SU7GTY, and Philips EL34. High and low Z settings used respectively. Distortion is quite low even at higher power outputs.

FFT 1mW into 32ohm



FFT 1W into 32ohm



FFT 1mW into 300ohm



FFT 500mW into 300ohm



Frequency response 1mW into 32ohm



Frequency response 1mW into 300ohm

Nah not at all, at least not in NE Ohio, just plain old boring critical care lately lol most COVID patients I encounter nowadays are in the hospital for other reasons and are incidentally COVID positive.
