I finally am done with the cabinet for the sx-650!! Here a quick shot
.
 
The front corners were painful. But I think that it came out pretty good. Certainly better than the stock cabinet.
 
Here's some irony. On the very day that I finish the sx-650, I picked up a 9090db.

   Yep. Couldn't resist the deal. I blame Moody for this one.

Looks good! And LOL @ buying the 9090db. I had one of those for quite a while...great receiver. Unless its been rebuilt, though, the Dolby board can be kinda problematic. Just something to be aware of if it gives you trouble.

If you get channel drop outs, that may be a sign the Dolby board will need work. Unfortunately for that design the Dolby board is in the signal path for ever source, even if the Dolby itself is disengaged.

Yes of course - the headphone out is coming right off the main power amp, as with all these vintage amps and receivers - that's the big benefit to them for us head-fiers!

I have restored at least 20 receivers and weak channels have been a common issue.  It has always been one of 3 issues for me:
 
1.) Bad solder joint (they usually have little cracks in the form of concentric rings due to heating and cooling over many years).
2.) A bad electrolytic capacitor in the signal path (this just happened to me a couple of weeks ago).
3.) Dirty volume, tone, or balance control (tape monitor switch is common too).  As already mentioned use DeoxIT (but not on Sherwood volume controls - it eats the plastic inside).
 
Good luck.

Hi, Speakerbox, could you shed more light on Sherwood issue? Did you mean all models (from earlier tubes to 80's stuff)? Or just some models in 70's? Thanks!!

Sure.  There have been a number of reports of the early 70s Sherwoods having the volume control messed up by DeoxIT.  Specifically these are the old APLS VCs with the integrated power switch.  The mail problem I heard about was the power switch portion of it no longer working after application - some plastic inside the switch deteriorates.  I did an experiment on an old Sherwood ALPS that already had a broken power switch and it seemed to negatively impact the volume portion too (the left and right side had uneven output after using the Deoxit).  Please note though, that this was a very old VC and the only issue I am absolutely sure of is the power switch part.

Great job, MattTCG! At-a-glance, I'm reminded of Yamaha (the cabinet) until pix comes in to

Thanks to all for the kind words and to everyone who pitched in to help with the acquisition and repair (Moody and Skylab). It's like Christmas at my house.
