API 500 Rack Compatible 1176
« on: October 23, 2007, 06:58:36 AM »
I've been thinking for a while about making an 1176 in a 500 rack format. I just found out that Purple Audio has come out with one, though it is without the o/p xfrmr.

I've also been drawing up a GSSL to fit two 500 rack spaces.

Anyone else here on that same wavelength?

I have also been thinking about this. Does the Purple unit have an input transformer?

There's a 1176 tube version too!

from the purple audio website "The Action uses our custom output transformer which provides two isolated outputs (when supported by the chassis)."

I will be buying at least two of these if they sound like they should!  Of course, If there is a board and faceplate available for a similar DIY I'd be all over that too!

Ed, -Just a quick FYI:

"Pants" in the UK means "crap".

In case you don't get many sales from Britain, it might be like trying to sell a chevy "No-Va" in South America! :wink:

yeah, i'm aware that some of the names don't have only positive connotations for people in every culture.  all of the names are words andrew peppers his conversation with, with no meaning relating to what other people think, on this continent or any other.

Well Mnats Rev D 1176 board is about the same size or SMALLER than a 500 card. So I am sure it could be done.

I believe someone else is already working on that one, but don't let that discourage you. I'd be interested to see what you come up with.

who what when where how?????

If someone else is mapping it, all the better (than my sledge hammer and chisel work).

I'm just working on dividing up the pc board into two, to fit the two edge connectors, and maybe provisions for xfrmrs.

1176 and gssl in 500 format would be great.

I would jump into it

I've also been thinking about this. The G1176 PCB's should fit within the 500 sizing, would require an extra pcb with the edge pins with wire connection to the main board, haven't fully looked into this yet though. What about the Mnats 1176 board, anyone know the sizing of the PCB?
