Bose 901 series 1 EQ question

[MaxP]

You can get a replacement equalizer at deercreekaudio.com if you want to go in that direction.

This is what I ended up doing with my 901 IIIs.

When you buy the 901-tuned miniDSP from Deer Creek, do you also get a download for the plug-in (the settings/configuration file)?

No. Just the unit and the RCA cables.

@viennadad have you gotten this to work, yet?

If you don't get eq with it positioned between the pre out and main in, your EQ might be sick and needing some work. If it does work there, then the tape monitor should work, too.

Tried using both tape loops and the pre out/in.
No eq effect in any. I suspect I have a sick EQ.
Going to see if I can track down a schematic.
Anyone have ideas on where to start investigating?

When you have nothing I'd suggest the best place to start is at the beginning; mains voltage getting to transformer, low voltage from transformer through rectifiers, etc...

Maybe you'll see a problem as soon as you open the case.

Schematics for all series eq, as I recall, are available on HiFi Engine.

Yes, HFE will have the documents.
