610 Consolette Chassis Overhaul SERIAL # 11535B
Hx of unit as I know it. It's a running 610 chassis but sounding very tired.
This is the chassis Buglegirl gave me to put in the 510 Consolette. She got it from Audiodon. The original 510 chassis has already been done.
Was getting bored, and this box of parts for the 610 chassis was nagging me to get used, so I went and pulled the chassis out.
Started by changing all the old "dogturds", and the leaking FRAKO electrolytics. Noted about 30 cold solder joints while replacing parts.
The output couplers are supposed to be .022uf, but .03uf's were in it. I checked the values of the resistors surrounding them and they were per the manual, so I yanked the .03's and put in .022uf.600V's.
The speaker screws were stripped so I put a pair of Ratshack 5ways in. I've got Banana plugs so it don't matter that they are right up against each other.
Ran out of Terminal strips and 47uf/450V caps. Order is in for those. I have enough 27uf 450's to do the isolated CAN CAP, But have to get new a isolation pad for the can. Gonna stuff that one. May stuff the 4 way if the caps will fit other-wise I'll go with Terminal strips and offboard caps.
The MPX addition is a little weird in the setup. Section 4 of the Rotary switch is probably different on the CE-III than the 610. On the 610 the wiring for the FM section has pin 9 and 8 on the back tied together with Pin 9 Front tied together with them. Pin 9 on the front has only R36 to ground on it.
On the CE III Pin 8 is used for the FM OUTPUT, and is tied to PIN 9 Front? But on the 610 switch that puts the back of 9 in circuit too. So I Moved the R36 from Pin 9 to Pin 8 on the front to keep the circuit as the schematic. (HOPEFULLY!!)
FM OUTPUT was connected to Pin 8 Rear Section 4 Selector Switch
MPX OUTPUT was connected to the Junction of C47 and R32-R35.
MPX INPUT was connected to PIN 9 Rear Section 4 Selector Switch.
If the MPX works on it fine, If it doesn't I can reverse everything in about 10 minutes.
It'll be a couple weeks before I get to finish it up with mouser order, and getting ready for the workweekend on the sub this coming
weekend and the inevitable re-couperation from trying to do a years worth of work in a weekend. As I get parts and do some more, I'll add to it.
The pics include the original 610 schematic of the area and the CE-III schematic of the same. No changes to any caps
or resistors need to be made.

Da Whole Enchilada...

Junk Parts. Every on of these caps are leaking according to my cap tester.
FUN, FUN, FUN!
