Sent a pm to one of the mods over there regarding this (didn't know which "jude" was jude.) Banning imminent I suspect Also, I assumed that no one ever asked one of the Fla. crew for their permission to use the name? Sorry, this has bothered me for quite some time (1st world problems, I know...)

Commercial trade show should pay Fla. crew for the use of the name Retroactively. Sent from my iPhone using Tapatalk

You could do Colin Toole's I/V stage... he may even have some boards left (you would need 2 if you intended balanced). I built up a balanced set and used them in the Adcom CD player that recstar24 had. You could ask him what he thought of them? http://www.head-fi.org/t/316795/discrete-i-v-converter-board

luvdunhill might match these for you, but you would need to contact him. He has a curve tracer (locky_z), and likes doing this kind of stuff. I'd ask his opinion on how many devices you might need to get a good match for 4 quads. I could probably do the board layout for you and integrate the es9018 stuff if you wanted that on board.

Re: 2SK369V This guy on diyaudio has them, but is in W. Australia with large shipping costs. Genuine devices though. You need 4 quads matched (16 devices)? You would probably need to buy 100 devices to guarantee this level of matching (and nothing is guaranteed). Might get lucky with 50... http://www.diyaudio.com/forums/vendors-bazaar/297423-toshiba-2sk170-2sj74-fets-other-semis-sale.html I had some stuff I needed and would consider piggybacking an order to split shipping if you decided to go this route.

^ Agreed Reks. I wish I could understand him better though Sent from my iPhone using Tapatalk

Same. Haven't checked them but they look fine! Thanks! Sent from my iPhone using Tapatalk

AOT is a resistor (R62) spot in parallel with R54 (10K), feeding the sense line on U3 (TPS7A3301RGWR?) to ground. Maybe used to tune V- to match V+? No value listed in the BOM for it.

I am by no means an expert on this, but I thought thermistors went in the primary wiring? Nelson Pass seems to use CL60s a lot, wired in the primary. 527-CL60 He may have changed, but this is what I remember. Hopefully some of the larger amp builders will chime in. This thread has some discussion of this.

Maybe some of these Amp receptacles? For 0.0252" pins 649-75915-304LF That one is a 4 position. Are you trying to find a connector type to connect the buffers to the ubal->bal boards? I actually think that Kevin should just put the buffers right on the ubal boards. They wouldn't add that much real estate, and if you didn't want to use them, you could just jumper them. The Phoenix connectors seem to add a bit of real estate on small boards such as these though

Paid. Thanks!

Were you going to do the SMD Ubal board? That's the one I was interested in. Also, I assume the diamond buffer boards are single, so you would need 2 of these for each Ubal board? Thanks!

I would think that incorporating the diamond buffers for balanced would be the way to go. Do you have a schematic for this board as well? Broken record time... Any chance of including footprints for 0.1" Molex KK connectors as well? Good time to duck now Sent from my iPhone using Tapatalk

I'd probably start with replacing the MJF15031 that you had in the wrong spot, and now is getting warm. Also, I would think that you should be able to get 15Vdc out with 15Vac in, since that would be ~19.8Vac after the rectifiers? And there aren't any Jfets in this.

You must be a glutton for punishment Steve I'd be in for some version of the ubal board, maybe others.

Happy Birthday Mike!

My GRLV didn't have the pot, but my impression was that it was used to balance out the +/- voltages, so just check outputs to ground? Or not use it...

Payment sent. Paypal address is fine, and I also PM'd you the same address previously. Thanks!

Are we to pay you the amount in the Remainder column? Sent from my iPhone using Tapatalk
