Just give Laura a call, or send her an email. She has always been very helpful. I've never had any luck with their online site, particularly searching

happy birthday dood!

Good first post

The digital in (coaxial or optical S/PDIF) has both channel's information in a single bitstream, so the cable could not possibly be the problem. It could be a problem in the DAC (output stage?). Or possibly in the transport (not sure what you are using).

Did some listening tonight, first with the CCS's at 56 ohm, then at 75. Same material, AKG K601s as cans as these are the closest to the 501s my brother uses. Used a Bernstein/CSO Shostakovitch recording, which my brother thinks is one of the most realistic CSO recordings he has heard. I preferred the 75 ohm setting by a pretty significant margin. The 56 ohm setting resulted in much more steeliness to the strings, etc. The 75 ohm setting tamed this for the most part (maybe all of it) and fleshed out the mids much more convincingly. I also thought the bass was better. Not sure as to which impedance switch setting I liked better though. The 601s are 120 ohm (IIRC). Would conventional wisdom or experience tend towards one or the other setting? Time to let my brother listen to it and I'll see what he thinks.

Nate, Are you asking him to ohm these out? Steve, I believe Nate means to use the ohms function on your DMM to measure the resistances between the points indicated. This should (may?) show you what area is shorted.

Happy Birthday Matt!

Just looks like some flux in the last picture. You've been given good advice... disconnect the amp boards from the PSUs (the red/blue/black groups in pic 3) and see if the PSU comes up with no load. Does this B22 have a single sigma22 or two? If so, disconnect them both. The wires I pointed to go to the amp boards, so you won't have any loose wires with voltage on them floating around doing it this way. If you were to disconnect them at the amp boards, then you have to worry about that. If you have a DMM and the PSU comes up, connect the black lead to one of the sigma22 terminals marked G. Set the DMM to DC volts (and if not autoranging, to greater than 30), then take the red lead and touch the V+ (terminal that a red wire is going to now), and then the red to V- (where the black wire is going). You should see +30 for the first and -30 for the second.

Happy Birthday!

Sorry if there is already a topic on this, but I couldn't find it. Anyhow, a woman robs a bank and not only leaves her debit card, but writes the note on the back of a prescription... in her name FBI: Bank robber leaves debit card behind - Chicago Breaking News

Step away from the crack pipe dude! These idjits commenting on things they don't have a clue about drives me nuts on hf anymore. If I wasn't selling a couple things I'd have no reason to even go there anymore. At least he admitted he was wrong, instead of the usual misdirection...

Holy fucking sheet Birgir! You're a beast! Can I have the spare aluminum?

She's a doll Naaman! Congrats to you and your wife! Beautiful name as well!

Did you read your welcome PM? If not, I suggest you do so. Reks seems to be in a better mood WRT the shovel, but I'd look out if I were you...

Happy birthday Tyll!

Got the tubes today, thanks Tom. I only thought you were sending a pair I put the two pairs marked 6J6 in. The first pair was marked 105/100 and 100/105. These measured PL of 124, PR of 114. The second pair (don't recall the tester values) seemed better at PL of 136.7 and PR of 134.2 IIRC. I measured the Vf across the 4 LEDs and all were 1.63V except for one which was 1.62V. The drop across the CCS resistors was 0.93V, so this makes sense (1.63 - 0.7 = 0.93). I didn't check the Vbe across each of the BJTs. CCS is right around 56.x ohms, so ~16.6mA right now.

Brent, sorry to hear that. Hang in there, things will work out.

Yes, plenty of clearance on the bottom. I found out inadvertantly what shorting the CCS resistor to ground does... one BJT and and LED and a resistor later Winter or whenever would be great Doug. Thanks Tom. I'll have to do some listening with this after I get it cased up for safety. I played around with RMAA a bit last night. Nothing I could do would get the distortion level down so RMAA would not complain about it. I also took a look with Visual Analyzer, and yes, the THD drops quite a bit as you reduce the signal level (not surprising). I'm still fumbling around with VA however.

Conversion of RMS to peak would be Vrms * sqrt(2), or 120vac * 1.414 or ~170Vac. Still in range, or should be. Even my little $5 Harbor Freight jobbie will measure AC line at 120Vac or so.

V~200 should have been plenty. Meter <-

I was looking the PCB over to figure out where to drill some holes to install SIP pins for putting the parallel resistors in when it dawned on me... pull the 75 ohm resistors, put SIP pins in their place, and solder the 75 ohms on the bottom between the pins So that's what I did...

Happy Birthday!
