1176 Clone ID

[Ghaleon]

Recently purchased a cheap 1176 Clone, would love some help ID'ing the build. Mostly I'd like to determine if theres a hidden "all buttons in" mode for the ratios, or if I need to mod something in.
Looks like an early hairball build to me? The main pcb has the marking "MNAT REV J" All the hairball tutorials I found have a ratio switch assembly, as opposed to one knob.
See attached pics. Thx!

It's just an old Mnats 1176.
You can achieve the "all buttons in" by shorting the ratio switch I suppose (it's a rotary contactor, not a knob, it's the same thing just different shape). Have a look at the schematics

You sure it's Mnats ? Looks more like Jacobs G1176 Gyraf Audio - DIY 1176

You may be right actually, by the look of the front plate.

In the end it doesn't really matter I suppose, to achieve the "All Buttons In" mode. The OP just need a double pole on/off switch to engage both 4 and 20 ratios.

Schematics are here : https://www.gyraf.dk/gy_pd/1176/1176sch.gif and the mod is described here : Gyraf Audio - Public Domain Circuits - DIY 1176

good shout. Found this page just before you posted it!

You can do the all buttons in on the rotary switch as a position 5, if you get a switch with 2 wafers. Use the 2nd wafer for all in mode.

Here's Mnats description of Rev J and the Slam mode:

If you just scroll down the page I posted above it tells you how to add slam mode to your paticular 1176.
