Hey, I know this is an old thread and any comment´feel rusty but..
The 1178 is a great tool, I use both the 1176 (DIY) one and the 1178.
As a gain red. device they react almost the same but as SSL-t. says its
a different constr. The 1178 use the 5566 Dil double fet and is perhaps
the only useful way to make a real stereo comp/lim if you compare
it to the 1176. The linearity between two fet´s in two different boxes over
10 dB gainred. is hard.
I think in opposite to SSL-t. that the 600 ohms T-bridge is nothing to seek for if your not at the end of a telephone line. If you normally put + 29dBu
at the front I think you should concider another way of working, or use the gainpot...
at the delivering device. Show me which console that put +29dB out at the
insert point?
The really sounding difference between the seeked blackface models and the new ones (not the reissued) is the class A output amp and to put
as in the DIY ónes a Tx at the front instead of the 5532. It make´s
a sweet blend and bottom.
To answer your question- no I dont think there is any PC-board made of
the 1178 and if you can live with those nonlinearities with two 1176 as
a stereo device. I think you should go for that. I have 8 channels going
including my 1178 (Org) and I´m very pleased.
Cheers Bo
 
To SSL-t. If you still got that awful device of 1178..
Trý this ; Put in a good high imp. Tx ( a Sowter, Jensen or a LL1540
or why not a Marinair 31267 and make a 2:1 or 4:1 connection)
insted of the 5532 and go right in to the 1 kohm pot.
If you decide a 1:1 conn. place a 1Kohm in series with the pot.
You get a 6 or 12 dB loss (and about 2 kOhm inp. imp.)
but there is sensitivity-room for that.
If you want a nother step, change those Frako caps to Philips ones
and replace the IC-2 ( 5532) to a 33078 and tell me what you hear.
Cheers Bo

Hey does the 1176 pcb that is sold around here have this thingamacig?

Also, are there any 1178 PCB's floating around? I know I have seen the schemos somewhere.
