[sorenb]

"Description (Gerbers) copper/pcb thicknes": Everything is one channel, and two will be needed for stereo.
As for the KGSShv PSU, only the Single Right Skinny is offered: containing one High Voltage rail and a BIAS supply. Those who needs a full supply will need two of those + the Golden Reference Low Voltage.

1. Überamp (Uber1 + Uber2) 4oz/2mm
2. Unbal2bal (Uber3) 3oz/1.6mm
3. Golden Reference Low Voltage (GoldenReference6) 3oz/1.6mm
4. Transconductance Amp (CurrentSourceAmp2) 1.6mm/3oz
5. KGSShv PSU (kgsshvpssicfetsinglenewright), 1.6mm/3oz
6. KGSShv Carbon Amp (Carbonv6), 1.6mm/3oz
7. Grounded Grid (.........) , 1.6mm/3oz (as requested by JoeHpj

A spreadsheet here to keep track of everyones orders.
Quotes are from PCBNet, and not yet confirmed but probably close.
The spreadsheet will automatically update the final price based on the total amount.

Two questions:

1.what's difference between Carbon V5/V6

2.would you please GB Ground Grid as well? PS: I think GB for ground grid DHT will be more convenient for those who want to use EL34 just need to connect the heater point-to-point.

Thanks!

Edit: checked the gerber. seems V6 shrinked a little bit from V5, other identical.

the carbon for dht definitely works as does the kgbh-bipolar-dht

the carbon for 6ca7 evidently does not work, congo5 has some spare boards contact him for a pair, might be an assembly error (doubtful) or some bad parts

the shrunk boards fit a 100mm heatsink vertically.

[gepardcv]

It says carbon v5 on the spreadsheet but v6 in the thread here. Which is it?

[sorenb]

Carbon v6, I'll update the sheet, thanks

[sorenb]

Carbon + PSU quotes from PCB added to the sheet.

The Row line specifying the actual board name is now conditionally formatted, will be red if total amount is lower than 20.

Is Uberamp the amp that can drive ESL?  

[Walter Reyno]

any chance for updated circlotron output boards for the Nanotube?

[kevin gilmore]

uberamp will drive anything i can think of. no protection circuits of any kind, and just about unlimited current capability.

[spritzer]

Who needs an arc welder then...   

[kevin gilmore]

With a sine wave generator driving the amp, would make a perfect tig welder. Change the frequency to control bead size.

[joehpj]

Class A welder

[brazilnut79]

Duty cycle estimate?  ..Seriously; Don't yet own a mig, tig or stick yet.

Inaugural use for an adjustable stone-top speaker stand fastened to standing-shaft über-welded steel plate? 

I just need to find the wide base hand-Crank.

What's the estimated time frame for this group buy? As in, when will the order be placed and shipped out?

[sorenb]

...I will go ahead and place the order except for Grounded Grid.and Über unbal2bal.
I have locked the prices (might change a bit when ordering due to some quotes were done for 2oz and not 3oz).

Please do transfer the amount listed in "Price total" to my paypal account: xxx@hotmail,com, putting "Group Buy, Uber" and Head-Case ID into the notes field.
Current Price doesn't include Grounded Grid nor Über unbal2bal.

Shipping will be added later.
I'll update the sheet whenever I have received payment.

 

The shipping for US/Canada is done from US, Maryland (Thanks to Jay) and for non-US/Canada, from Denmark.

Sorry, please cancel my order. Thanks.

Are you grouping these boards for shipping with the attenuator boards for those who ordered both?

[GeorgeP]

Pm'd, but thought I would post it here in case others were wondering - is there still time to add one's name to the spreadsheet?

[kevin gilmore]

congo5 wants me to make the output transistor mounting holes an additional .1 inch, so there will be another board rev. board will be .2 inches bigger, so might slightly influence price.

Can do if you want, or somebody else wants that - I'll add a cloumn for "Combined Ship w. Dig. Att."

I would like to combined shipping with attenuator boards .

 

I tried the spread sheet.  It cannot be changed.  I guess it is locked
