Hi all,

I'm going to do a board run for Dr Gilmore's latest projects (KGSSHV, Dynahi Rev A and DynaFET) so if anyone is interested, please sign up here.

The KGSSHV will be the latest revision. Board set would be 2x amp boards and 1x PSU board. The amp boards are now mounted on side heatsinks.

The Balanced Dyhahi Rev A and DynaFET will share the same PSU. One PSU is enough but due to the symmetry, 2 would surely look better Board set would be 2x amp boards and 1/2x PSU board(s).

The boards will be made with the same specs with the T2 boards I did a couple months ago.

Not sure about the price yet but I don't think it would be awfully expensive. Of course, the more the cheaper.

Whenever I have the boards, I'll try to post the BOMs for them.

So if you are interested, please let me know here what you want. I'll send out the order tomorrow for price quote.

Spreadsheet: https://spreadsheets...npReEE&hl=en_US

KGSSHV offboard $29.38

KGSSHV onboard $33.63

Extra KGSSGV PSU board $14.79

Dynahi $39.84

Dynafet $39.84

I'm in for 4 KGSSHV sets and two Dynahi's.

i'm in for 2 complete sets of everything.

I'm definitely in for a set a set of KGSSHV boards as well as a Dynahi board set.

In for two sets of KGSSHV.

In order for easy track, please check out this spreadsheet. https://spreadsheets.google.com/spreadsheet/ccc?key=0AnqARwsQ1QV7dFRhVnIwTF92OTVQS3RlQnNpNWxtSUE&hl=vi&authkey=CMyJv4QP#gid=0

Let me know if you can't fill it out.

Should you have an option for 1 or 2 PS boards for the Dynas?

In for a set of KGSSHV

Just added a column for the PSU. Mark 1 or 2 and I'll calculate the total basing on how many Dyna sets you need.

Wooot....been waiting for this. Thanks Lil Knight, and of course Dr. Gilmore!

Count me in for:

-4 KGSSHV sets

-2 Dynahi sets (4x PSU's)

-1 DynaFET set (2x PSU's)

Kevin, I assume the hole spacing for the various output devices is that of the T2, not the previous spacing of the Dynahi boards (weren't these different?)?

Wow, this is what I call efficiency. The boards have been checked over the schematics already, right?

Just to make it crystal clear, the quantities are for number of board "sets" and not individual boards correct?

So if you want to make a KGSSHV amp, you would need to mark yourself down for just (1) KGSSHV. It seems like some people may have accidentally marked themselves down for number of boards needed, and not board sets.

The number is for set. 1 for KGSSHV is all the boards needed. The only option is whether you need 1 or 2 PSUs for the Dynas.

Hi Lil Knight,

I would like to have one set of KGSSHV, please. I've updated the spreadsheet.

I am in for 2 KGSSHV sets

updated spreadsheet

Have these all been checked over by others to make sure there are no errors in the boards?

Edited June 28, 201114 yr by deepak
removed myself from Dynahi list

I would guess that these are KG's layouts?

That said, on the previous DynaFET GB, I don't think anyone has gotten theirs working yet, with the exception of KG?

luvdunhill ?

naamanf ?

vvs_75 no

Digipete no

j4cbo

Kevin Gilmore think so

looser no?

Pars kinda (no)

Smeggy ?

digger ?

Team Spain no?

Icarium no?

Edited June 28, 201114 yr by Pars

Team Spain got one half working (just 1 pair of output FETs afaik) but there's a random high frequency oscillation which is being evaluated

I need to see if I can find a decent chassis with heat sinks attached.

No T2 board sets up for grabs?

I want a set to squirrel away like a nut.

Absolutely brilliant, I was hoping this would happen. Count me in for a KGSSHV set.

I'm in for 2 sets KGSSHV

Thanks for doing this and to all who were involved

Edited June 28, 201114 yr by HDen

In for four sets of KGSSHV off board.

Edited July 4, 201114 yr by wink

4 KGSS 2 Dynahi, thanks LK/KG

In for 2 sets of the KGSSHV, spreadsheet updated

Thanks!
