EDIT: Nevermind, it's more for me who's going to be using a different attenuator.

    I've got the permission from Dr Gilmore for a second run of boards, so let's do it again.   Linky to the spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0AoNVeoQi85GgdFVrMmtReVpWNVBsQUo2Sl

  • LK, you shouldn't end up out of pocket for this GB!  If those shipping cost don't start working out to break even for you please let me know and I'll be happy to do what I can to assist with closing t

  • I kind of went overkill on it...   HV 420V 430mA x 2 17-0-17 1.2A   6.3vdc power supply 9v 30VA   6.3vac filaments Using 3 (2x 30VA; 1x50VA)   For the PS board I'm using 2222A instead of 3

No biggie. What on earth are you going to do with 6 KSA5? :)

 

I will close this GB on Thursday next week and send out the order to get the quote.

spread the love.

Thanks for doing this Lil Knight. Updated the spreadsheet with what I want.

Hope you don't mind new members joining up. I'm in for one Dynahi onboard.

Oh woow

KGSSHV I'm going to have to join in on this :)

Maybe the KSA5 too, I liked the KSA50, so the KSA5 could be interesting, besides it could always sit under the pc's desk to keep my feet warm in winter

 

then you want a pair for balanced, one for each foot.

 

Hmmm

Balanced foot warmers. :)

I suppose I could always use a pot for the bias....

Then I'll have temp control... :)

next stage ... remote control for temp control...

Who said DIY is excessive? :)

Looks like I will include the KGSSHV mini PSU for the Megatron.

So each set of Megatron includes 1x amp board + 1x KGSSHV mini PSU.

 

I am also working on something very similar to the Sigma22, will include that with the Dynahi, if you want. Or, AMB shop is the way to go. :)

Tran,

 

In light of the clarification that the KGSShv mini PSU will be used for the Megatron, I have removed my remarks in the remarks column accordingly to avoid any confusion.

 

Thanks for everything Tran. ::)

I know that Glassjar sells Sigma kits, but lately there were reports of problems with communication.

 

In any case- worth checking out!

Many thanks Tran for another group buy.

Yeah, indeed. Their communication is quite arbitrary.

Recently I had to wait one week to get their response for a single transformer.

 

Most of the S22 parts can be ordered from Mouser though.

 

It's great to see the big interests in the Megarton. I built a Megatron some time ago and current draw was about 122mA for the 500V sections and 11 mA for 300V section. If I remember correct the current limit for KGSSHV PSU is about 90 mA. Maybe one mini PSU won't be sufficient for the Megatron, unless some modification.

 

Many thanks Tran for another group buy.

Thanks for the heads-up, Joachim.

Hopefully Dr Gilmore will chime in about this.

the 300v is made from the 500v with a resistor, or a separate supply.

 

I don't remember about the current limit at the moment, will have to look

that up later.

Hi

 

Can you put me down for a krell board?

 

Which PSU do you guys recommend?

 

Cheers

 

John

Is the new dynalo board gonna make it into this group buy?

 

No but the Squarewave would be a good alternative.

I will stretch the GB a bit, maybe 2-3 days, for further testing of the new mini KGSSHV onboard. Hope you guys don't mind this.

I don't remember about the current limit at the moment, will have to look

that up later.

Did we figure out if the new mini PSU was gonna work?

No worries, Lil Knight.  I don't exactly have lots of free time to build amps right now. :)

No problems Tran and thanks for being so deliberate with the whole group buy :)
