Happy belated Birthday JP! Looks like you had fun (saw your post on FB).

Nice to see you back again Indra (hope I remembered that right). Sorry, can't help you much on DACs as I still only use a CD player, with another as transport for it. People tell me that SPDIF still sounds better than USB, but with your envisioned setup, USB would be much easier unless you wanted to get an interface. The Schitt Yggy seems to be well thought of, but not sure what those run these days. They do seem to come up used fairly often. Someone should pop by shortly with better ideas. Take care!

Happy Birthday Chris! Hope you get some good fishing in.

Happy Birthday!!

Normally around Thanksgiving in years past, Modushop has done a sale at something like 20% off. A couple of years ago, they included the customizations in that sale, which is where they get expensive with the machining, anodizing, etc. I did my DynaFET and Salas FSP cases on one of those. Still not cheap, but probably quite a bit cheaper than finding a CNC machine shop, designing your own cases, etc. as Kevin did for the T2's.

On the CFP3 that I worked on for purk, built by Dukei/Miroslav I believe, the GRLVs were using A1943/C5200 IIRC and seemed to work just fine.

Happy Birthday Marc!

Our cat sometimes sleeps inside the bass drum of my son's drum set, crawling in thru the port on the front head. Helps that he has a small pillow inside as well.

Happy Birthday!!

The thread on diyaudio might be of interest to you re: OPA828 vs. OPA627. Schitt equipment seems to be well engineered and built, to very attractive price points. Unlike some others in heavy shilling/pimping these days 9<<cough>> Topping <<cough>> https://www.diyaudio.com/community/threads/opa828-opa2828-vs-opa627.400109/

I've never built a T2, so take this with a grain of salt, but anytime I see DC levels bouncing all over the place, one of the first things I would suspect is oscillation somewhere.

Will the 5V LT1021 work in shunt mode? I didn't think it did? Kerry posted a design using a MAX6138 reference which would do 5V back in 2018:

That sounds reasonable in terms of the pots and their action. I couldn't comment on voltage before clipping, but I guess around 2.5Vac for a front end sounds reasonable. Kevin could probably tell you, or maybe the guy building the CFP3s on head-fi (sorry, forgot his name). Glad you found the problem with the opamp socket. That is a strange one.

Are you asking about the bias for the ubal-bal tube stage or overall for the CFP2/CFP3? For the CFP2/3, it is generally 150mA, which is also what I run my DynaFET at. Not sure for the tube stage, sorry.

Happy Birthday Wayne!

RIP and Happy Birthday!

Happy Birthday Jim! I hope you have a great one!

Happy Birthday!!

Happy Birthday John!

16.98V is about what you would get if you had R7 and R8 swapped. Check the positions on the board.

RIP to your friend Jimmy, Brent.

Happy Birthday!

I would think cfp2hmt as the latest one.

Just started watching this last night (s1e1). Enjoyed it, and will continue.

Interesting. Where is a good source for forming taps?
