Firstly I'm not a fan of these. Smile Anyway a friend dropped one of for me to peruse. It looks like it's hardly ever beeen used, and I'm told  it has been connected to some shagged bass cabs.

ODEP LED out LH ch. A quick check reveals a few o/p devices and at least one diode. I'll need to remove bits to test further. 

So I looked online for a manual. On the Crown webpage you can download them, yes, but the diagram pages are now blank. HSE!!

Anybody got a diagram they can post or email? Then of course the subject of o/p transistors. Stick with matched or not. The school of Crown fixers is around 50/50 as to you must, or 'I have done this forever and no issues'.

Why would a retired old geezer like me look at this? Ha haa. Charitable.

Best Regards,

Thanks Elliot. That is the same. Scroll down to the schematics. They are blank pages.

Prior to the schematic section there are exploded views of all the components in the amplifier with a thorough listing of the parts. This is located in the "Parts" section.

Best Regards,

I can see the component overlays Elliot, but nothing of diagrams listed as section 6. This is the same on many I have looked at. ' This page intentionally left blank'

Good Luck!
I always replace all output devices (all even just one have failed from 12 per channel) with MJ21195-MJ21196 or MJ21193-MJ21194.
 
Check mosfets on VZ stages too, if failed, replace NE555 too!

Ha ha. Hi Claudiu.

I'm just very miffed that once again the circuit diagram (ENGLISH) (schematic) is not on the website. Last time I asked it was about health and safety.. WTF??

Not removed enough to check thoroughly yet as I was looking for a diagram, which is blank in all downloads I have seen so far. Yet another load of BS to me :) 

I can't open that file you posted without some 3rd party BS, which I never do.

Click Up corner right on download link, or on individual parts.
 
Or try here, but excuse  sitehost advertisings (sex content)...
 
 
Or give me your email to send it directly.

It's the schematic part of the upload... can't get the rest to upload to SP as they're too big. Send yer carrier pigeon and I'll send the lot up.
