That's only 53C, so not that hot. I know TDA1541As habitually run hot.. many develop distortions, lots of time only in one channel, so you will see people putting DIP heatsinks, etc. on them. Never measured temp on them nor read temps anywhere though.

Vintage DAC: Sonic Frontiers SFD-2
AES/EBU is supposed to be 110 ohm (like SPDIF is supposed to be 75 ohms). An XLR connector is not. The majority of implementations of either are also not properly terminated at the char. impedance. And probably don't use coax or controlled impedance cabling/PCB traces either. It still works, but not optimally. One probable reason why digital cables sound different.

Please help me diagnose a problem
I assume the panel is metal? Aluminum? Steel? You could probably get most if not all of it with something like an xacto knife or the like. Possibly have to carefully drill it out. Or use a ream, again carefully. That jack doesn't look familiar. Was it completely broken apart like that when you opened the amp? That would explain the no resistance. But yeah, the entire jack needs to be replaced.

What did you do today?
Like they said. Sorry to hear that Duggeh.

Mac OS-X (Tiger) file recovery
I looked at that. It wasn't that stellar. Nice backpedal BTW!

I don't know what kind of jack this uses, but yes, you should definitely feel resistance as you insert the plug into the jack. On normal Neutrik switched jacks, when the plug is inserted, it lifts contacts off of the switched set of contacts used for preamp or whatever, thereby taking them out of the circuit. The fact that the pre outs still work would indicate that the plug is not disconnecting these. I would think it should be an easy fix.

Post what you're watching
Seems like they put Terminator in the Friday slot preceding Dollhouse when it was intro'd. Didn't do anything for Terminator (other than ensuring it got cancelled), and almost took out Dollhouse as well. I know Terminator was expensive, but it does suck that it got cancelled, particularly with the other really mediocre shit that is on.

Vintage DAC: Sonic Frontiers SFD-2
I'm guessing most of the diff you are hearing between the D1 and this is due to the output stage. I wouldn't personally bother with opamps (other than maybe an OPA861 transconductance stage), but would go for a discrete stage. Zapfilter would be the easiest, though probably not the best. If you do decide to go the Burson route, I would probably do one of the Audio Gd ones, as I suspect that they actually make the Bursons, and theirs are more reasonably priced. Note that for I/V duty, a discrete opamp << a discrete zero feedback I/V stage.

Happy Birthday Pars!
Thanks for the wishes all! I had a nice day.

Empirical Audio USB Off-Ramp Turbo 2
I was still under the impression that few do spdif termination correctly, even now. I would agree that Empirical products aren't what I would call a good value

What did you do today?
Yep. Hang in there and things will get better every day. My thoughts are with you and your family as well.

Cool. Now just renew Sarah Connor, the Unit, uhh... what else? The Shield? Oh sorry, not gonna happen on that one.

I was trying to think of things I needed from Newark after you posted the coupon. The HLMP-D150 I recognized (dyna something). Neon lamps? Those could be interesting. Didn't realize Newark carried Caddock... will have to see what they have in the TF020 series (IIRC). 25% off those could be tempting

Group Build: Dynafet
Another product line that might be of interest: THERM-A-GAP 600 Series Gap Fillers I have some tubes of this at work (T644; not sure where they came from and what we used this for, and they are expired).
-
Go figure
Apparently the Crystal chips (discontinued) were much better sounding than the PGA23xx series, partially (or mainly) because the PGA series has a built in opamp which is essentially an OPA2132/4. I had a Coda preamp with a PCA2310 (IIRC) in it, and I thought a TKD pot was more transparent.

Suggestions for closed headphones?
Hmmm. I have 271S at work amped with a Gilmore Dynalo. While not bad amped, something better would be nice as long as it wasn't too pricey. The ATH ESW9 sounds interesting, so I did a google on it and ran across this: Audio Technica ATH ESW9 wood headphones earphones At that price, that has to be a scam I would think? Or are these guys legit? Paypal only (so not alot of buyer protection).

Go figure
Yeah that is normal behavior... for a pot that has DC on it. Not good.
