zenith 5k29 with bass boost crkt

[blaise]

1963 zenith console stereo w/tt. I have preamp schem. Need output schem.
Also if anyone has modded or repaired. Looking for tips.
I want to use amp alone and plug in cd,mp3, tuner.
I have already replaced some caps that were out of tolerance.
Not sure how large a signal I can apply before overdrive.
O-scope took a dump on me, can't afford a new one right now (bummer)
Also cant find specsheet for OT's

My experience with these older consoles is they where designed as a complete system.
If you are running the power amp without the preamp, you may have to rethink the coupling cap values.
Up, down. Depends on what they where doing in the preamp.
Try it both ways. With & without the preamp.
You'll hear what I am talking about.
Then again, there very well may be no difference.
As to the power amp schematic, your best bet would be to sit down & trace it out.
Start with the layout. Then draw up the schematic.
The awareness you get will certainly come in handy when it comes to modifying the circuit.

Yeah I figured I might have to trace it out. Fortunately its not too busy, and I will definatly look into the coupling caps. Thanks for the pointer. Here's a pic.
