  3. I am running 200mA bias current and 22 VDC rails now using a 200VA trafo with 22v secondaries supplying 4 boards and the Sigma 22 heatsinks are quite warm to the touch at 45 C. The Sigma 22's dropout voltage appears to be about 8-9 VDC which is consistent with the AMB documentation. If I had known how good this amp is I would have made it a full-blown, dual-mono, two chassis build with PSU in a separate chassis so I don't compromise its performance. Unfortunately the chassis I picked for it has barely enough space for a single GRLV so that's what I will do. Waiting for parts to finish the PSU and I will report back if a single GRLV is adequate to supply 4 CFP2 boards with 200mA bias current. In it's current setting, the current draw on each rail is about 850mA 4 boards combined. Here is a photo to show the chassis I am using.

  4. I was PM'ing with another headcaser about the practice of lifting the resistors off the PCB board for high voltage applications. I improvised a method that I have used for all my builds so far and thought I would share it here in case others may be interested. See the attached pics, I used a lead bender I bought which has a provision that works perfect for most of Kevin's layout where lead spacing for the resistors is about 11mm. To lift the resistors off the board, I put 5mm tall standoffs with a washer to make the total height about 5.5mm. This works great with KOA Speer 1/2W resistors which has a diameter of 3.5mm, thereby provides a 2mm gap between the resistor and the board. I make sure I do this on a flat, hard surface so all the resistors come out uniform height. I usually solder one lead first , exam to make sure it was not crooked, then solder the other lead.

  9. Or just put a zip tie under and solder the top side of the board.

  11. the only one with a lifetime warranty was the liquid carbon version 1. https://item.taobao.com/item.htm?spm=2013.1.20141003.7.4edb00b7muYKyQ&scm=1007.10011.70203.100200300000001&id=560442101039&pvid=d455e4ef-3a60-417c-9653-9dc0aea4d782 this guy will repair your piece of shit for you, the shipping both ways is going to be more than a liquid carbon is actually worth. my offer to ONE and only ONE person, send me your liquid crimson (the only one I don't have schematics of) and I will fix it for free. (plus parts and shipping) options can include turning the output stage into bipolar.

  13. Work went great. I think I'm going to fit in just fine. After work, I drove the scooter back to Fairfax, where it promptly died in the 7-11 parking lot. Glad it got me back to Fairfax at any rate. So Al's tenant Frank (the motorcycle whiz) helped me get it into a friend's yard and off the street. Then when going over the charging system, we found a loose battery cable. Cleaned and tightened up the terminals. It was down to 5 volts, so we put it on the trickle charger overnight. Hopefully, the battery will be fine, hold a charge and work well as transportation again. It really is kind of ideal for working in the city. Fingers crossed and major kudos to Frank! I did have to listen to a 40-minute speech on the history of motorcycles but it was well worth it for all his help. Then he insisted on buying Suzy and me dinner at Good Earth foods, though I tried hard to treat him. No go, Frank is a hard guy to repay a favor. But he sure knows his bikes.

  14. Fired up the smoker today while working on the deck. The ribs came out great (there were 4 sets like this is total) and the deck isn't looking too shabby. Still have the other half of the railing to do but now that we've got it figure out it should go pretty quickly.

  15. well this guy clearly has no clue, and does not understand capacitance. or the voltage ratings on the wire. and i'm not going to sell him any 5 pin stax plugs reminds me of the idiot that made a krell ksa5 power cable filled with magic pixie dust and managed to get the wiring wrong and did a number on that amp.

  16. Got this gem today... I mean we all know the cable makers are idiots but this is just priceless:

  17. Enigma has passed away. We loved her with all our hearts. She was kind. She was tough. She was smart. I'll never be able to express my gratitude for all she gave me. Tears on my keyboard.
