Can't wait to see a video of it in action! Just fired mine up with a fresh set of D's. Playing FM Attack and that almost always hits the number 6 on the M90 volume dial. It's sitting on the stove and I can feel the ceramic tile floor thumping with the bass on the other side in the dining room. The warmth of the bottom end is truly amazing in the right atmosphere. Most all my boxes sound good in the kitchen. I have to dial down the highs or I get fatigued with this box. My others can't produce as crisp of highs so I have to remember this is another animal and respect it. If I am not careful it will leave my ears ringing with ambient (white noise) in my hearing for hours after a session with it.
The M90s are no joke. They'll leave you deaf if you jam up close too much over 3 or 4 on the dial in an enclosed room of your house.

Transisterized, This thread isn’t about your M90, it’s about Chris’s. There are plenty of threads on here already about your Conion and m90.Transistorized said:

Congrats Chris on achieving your ultimate Boombox collecting goal - a mighty M90!
BTW, you’re just been kicked out of the ‘Loosers with no M90’ club!

Hey everyone, again, thank you (as always) for the up lifting words. This thing still has my head spinning.
I really had come to the conclusion that I would never have one. Like JustCruisin, I was fine with it. But I'm not gonna lie, seeing blu_fuz dealing in M90's like a drug dealer from Miami Vice has been a little tough . Watching people trade away their "Extra M90's" has hurt a bit. And actually seeing what $500 gets you off eBay made me want to 
.
So, yeah, I consider myself luck as **** to have it in the collection.
And the work begins. Even before this radio arrived, I purchased a copy of the service manual from Analog Alley and prepared to service the deck.
But because this is seriously over my pay grade, I have been chatting with DOCS. Together we have been going through the components one by one on the deck PC board and it looks like we may have found the culprit. parts have been ordered and soon we will find out!
I am very confident we will get the deck dialed in, as it's very clean, all the components move freely and it doesn't look like it's been molested in it's life time, which is always good.
More to come.

I would think a Victor would fall into your hands, but I know they still go for good money in Japan.nikonfoo said:
Thanks for the heads up. I'm not sure if I'm going to go any further in the clean up. It's a really nice original box. I may just leave it as a survivor and not overly restore it. But who knows.Reli said:

I love that stack pic with the 7979! 
I cannot be too bummed by not having an M90, because I've bought half a dozen C-100s instead..

I agree Rudy. While I see how you would view it that way, it was not intended as such. I was sharing a common interest with a fellow M90 owner while providing my own experiences.Hisrudeness said:
That was my approach as well Chris.Lasonic TRC-920 said:
Also, I noticed that you had mentioned that you had diagnosed your cassette deck and had parts on order. From what I have heard on these, the resistor style fuse fails at the top of the board and causes the PCB circuit to go open causing the deck to go dead. If all else looks good, I am very confident that you will have a 100% working box. As mentioned before in my previous post, I can't wait to see it back together (hopefully a video) with a big smile on your face. My experience seems to indicate that it certainly will. Heck even looking at it knowing that it's finally in your possession I am sure will bring a smile on its own
I have been working closely with DOCS, he has been walking me through testing each component and indeed we did find at least one of these fusible resistors burns and reading the wrong values. DOCS suggested replacing them all (4), so those are the pieces that have been ordered. Because I have shipping issues here in Italy AND the seller was in the UK, DOCS was kind enough to order them for me and will forward them on. Fingers crossed. I'm very confident this deck will run again as it is in exceptional condition inside.Transistorized said:That was my approach as well Chris.

You are so right Glu, nice to see you on the boards.Gluecifer said:
Yes man, and I really appreciate your help. Some serious hours have already been spent. So I owe you!docs said:Yeessssssssssssssssssssssssssssssssssssssssssssssss
Well done on all counts because these are worth it in every sense.
It is, but it's not the easiest to reach.hardmen said:
Again, to everyone one on this site. It's been one hell of a journey and I really have appreciated all the amazing folks I have spoken with here and face to face. You all ROCK!

The fusible resistor for the solenoid was frying up on mine. I remember turning it on and watching the solenoid stay engaged solid, as my finger could feel the resistor get too hot to touch after about 2-3 seconds. It shouldn't stay engaged longer than a second or so, it draws a lot of power and may be why the fusible resistor is there.
If memory serves, in my case I think it was because the opto-sensor couldn't get a reflection off the drive gear, and was unable to tell when the drive gear was in the reset position and is time to disengage the solenoid.
