16 channel discreet mixer

[nashkato]

just bought me a 16 channel mixer .
seems to be from the 80ies .
modular design built into a touring case ( which i removed/modified cause it was too big and heavy for my taste and i don't travel )
it's completely discreet ,penny giles faders, never have i seen so many doas in one place.
here's a quick shot

Wow. That is way cool. How does it sound?

 

[nashkato]

well , there's work to do :
some faders and pots are sticky ,
there's a slight L/R imbalance
and it's sensitive to physical movements/pushes .
soundwise it sounds very brite / brittle , kind of hissing and also seems to be lacking bass .
i need to investigate that further once another mixer restoration is finished.
but it's about 40-50 years old , so....

Lack of bass sounds like failing caps in the audio path

 

[nashkato]

yes , i'm afraid i'll have another recap queued up.

 

[nashkato]

this is a channel.
it got :hf,mf,lf,pan, gain, echo(aux), monitor
on the back : mic in , and 2 jacks : line in , chan out ( which are the insert as well)

 

[nashkato]

recapped 2 channels yesterday , just to see what i does and i'm blown away :
what a difference ,i suddenly can hear things , what a detail and stereo imaging , what a resolution , and not even yet recapped the masters.
( and i imagine to have some background on mixers to compare to)
it looks from the outside like a cheap old mixer that can go to the dumpsters but sounds like ... cannot even describe , words won't do it justice.
cheers

Says Acousta on one of the boards?

 

[nashkato]

you're right
and now that the cat is out of the bag, here's how it looks in full

would love to hear it once you get it all sorted.

I counted 8 transistors on one of the vertical boards and 6 boards in a channel. That's 48 transistors per channel.
