Connecting Bose 901 Equalizer to a receiver or another graphic equalizer

Greetings!  I've read a lot of the discussions posted; contacted Bose, Yamaha, Sony, and Kenwood, and still can't figure out how to reconnect my 901 EQ to my system.  Before I moved, the EQ/speakers were connected to this system and worked wonderfully.  My receiver does not have pre-outs but it does have tape play/record and so does the Kenwood EQ.  If someone can assist, I'd be very grateful.

I see a lot of people do not like the 901s.  When I graduated high school and joined the Air Force in 77, I purchased 3 pairs of 901s in Okinawa JA because at that time I loved them.  The pair I kept all of these years are the special edition oak cabinets on stands.  Several years ago, I had the speakers (tweeters) rebuilt.  I have an emotional attachment to them now.  Thanks for your help!
You hook the EQ into the tape loop and then activate the tape loop.

If it's not working, check the fuse? No idea if it has one..
Check and make sure your cabling is good..

I never used a Bose EQ, I always used an aftermarket.. PEQ not GEQ. They use to cost more BUT they actually worked.
To be able to notch a filter and add or subtract gain is pretty important.

Try the Bose community? Not familiar with Bose equalizer but I'm thinking the path to the receiver goes tape out of bose equalizer to tape in on kenwood eq and then kenwood eq tape out to receiver tape in then receiver tape out back to bose tape in? Seems like the logical path to me. I fully understand that emotional attachment as I have Sansui integrated from 1974 that I cant' part with! 
i agree that if your unit does'nt have pre pit main in then you have no choice but to use the tape you get sound when using the tape loop? if not, your eq maybe defective!!
Thanks for your quick responses.  I will try some of the recommendations this afternoon.  The frustrating part is I know the system works...because it worked before.  If I can't get it to work, I will look for a receiver that's compatible with the Bose EQ and has the pre-outs like the Yamaha RS-700.  Thanks again.
Corrected, I think. 

"...the path to the receiver goes tape out of kenwood to tape in on the Bose EQ and then out of the Bose EQ to tape in on the Kenwood. Switch the tape monitor on and off and you can hear the difference.  If you get it wrong just switch one end of the interconnects and it will be right.

LOL This is the Bose community, just most of us changed 35 + years ago. They are still in the shop somewhere under silks, along with 20 + other pairs of retired, or in the process of being made speakers..:-)

OP it is "OUT IN, OUT IN. Out of the tape monitor into the EQ, out of the EQ and into Tape 1 or 2. Select the tape loop your going to monitor (1 or 2) and make sure your plugged in there. 1 or 2 (if you have two) And engage the monitor switch or button. Actual pre in or out is not the best way, that is NOT passive, it is in the path and active.

The cables, the wire inside and components were just CHEAP...

It's better to use tone control and see if the "LOOP" is better or worse. In the preamp path you can't disengage the EQ.. Your stuck with CRAP.. OK...

Thanks for the suggestions but I must be an idiot!  The back of the Kenwood graphic equalizer has line in/ line out. It has tape A and B REC and PLAY. I tried going from the Bose EQ tape out and tape in to all three of the options on the Kenwood EQ. When connected properly, I remember being able to push the tape monitor button on the Bose EQ and it would engage and disengage. I can’t get the Bose EQ engaged. I have a masters degree in education but I may need someone to speak slower.  Is the Bose EQ or the KENWOOD EQ connected to the Sony receiver or just to each other?  Does anything connect to the amplifier connections on the back of the Bose EQ?  I appreciate your time!

I suspect you have the Series III version, but it looks like they have all the owners guides there for you to find. 
You should connect your receiver to the “amplifier” connections on the Bose EQ. 
There are many ways to daisy chain in the Kenwood EQ should you desire to do so, but connecting to the Bose EQ “tape recorder” connections might be the most versatile. 
Good luck!

(I was a Bose fan in 1977 too!)
Sorry, please ignore my suggestion to connect the Kenwood EQ to the Bose EQ tape recorder connections if you want both EQs summed. (Surely Bose did not send EQ’d signals to the Tape connections.)
When I connect the Bose EQ amplifier in/out to the receiver “tape” in/out, “tape” must be engaged on the front of the receiver.  This won’t allow me to “play” another device. 
I believe when the Bose EQ was connected to the Kenwood EQ tape  “A” and “tape A”” was engaged on the front panel, this allowed for the Bose EQ to work. I also remember being able to turn the Bose EQ on and off by engaging the monitor button on the front of the Bose EQ. This isn’t working now. 
I’ve talked to Bose tech support several times, Kenwood support, and Sony support. No luck. Any other suggestions besides getting a new system. 😜. My wife has already suggested that!  😡
Just trying to help Bill. 

“When I connect the Bose EQ amplifier in/out to the receiver “tape” in/out, “tape” must be engaged on the front of the receiver.  This won’t allow me to “play” another device.”

Yes, it should allow you to play another device. 

The whole purpose of a tape loop is to allow the selected source (e.g.phono) to be routed to a tape recorder to be recorded. Invoking the tape monitor on the receiver, then switches to what the tape recorder is putting out, which should be the same as what the receiver is feeding it (e.g. phono). The Bose EQ is just a pass through with EQ. If you disengage the tape monitor on the receiver, you should hear the selected source (e.g.phono) directly without the EQ.
