My Crown 970 from wild, have many problems and some of them, needs a service manual (not found in any place) or a help of some member as own one as well.

Mine has on a technician hands right now and he needs to know where battery cables are soldered on the power board, and about a transistor that mine needs... ...just have the transistor legs here (what code).

I could take mine apart and try to take a photo of what you need.

Q602 should be 2sd361e

 

R603 (now just a jumper) should have been 4.7 ohm 1/4 watt fusible resistor.

 

Be careful.  Those "legs" might actually be a replacement transistor soldered from the bottom up.  Sometimes, people do that so before you solder new transistors to those legs, just make sure that they are actually just legs and not a transistor on the bottom side.

 

Anything else, you should just buy a service manual.  It's part of the cost of caring for these old things.

This what mine looks like.
Not sure what battery wires you wanted.
The code looks like D861 (or D361 hard to see), 13D2

Hardmen, PM me if you still need the service manual.  Otherwise, hopefully the information already provided was sufficient to get your boomer fixed.

 

Norm, did you have the Service Manual on Analog Alley?

Thanks for the help Norm and all..
