Gibsonian's Cherry Pl 700 Ser I, soon to be a PLWO-1000

Thanks Joe, appreciate the education!!

One 21196 output was shorted on the right channel negative rail. We will now replace the 4.7 uf electro with a poly or poly.

 

[laatsch55]

Found some 250 Volt 105K's in the stash. Polypropylene. In they go. As Joe likes to say " A thermal Event occured" with the first two.

 

[Gepetto]

That was quite the thermal event Lee...

 

[laatsch55]

Yep sounded like small firecrackers. Now Jani's heard me short outputs and other various snaps , crackles and pops , but this was a new sound coming from the mancave and had her undivided attention until she heard the unsolicitated " I'm OK hon".


Getting crowded in there....

 

[Skratch]

You got to watch the polarity on those electro's on the negative rail. The negative goes to the B- and the positive goes to ground.

Wow.. sort of like what happens to you after a bad bean burrito..

 

[laatsch55]

Sort of....

 

[laatsch55]

Just got in. After dinner we'll get down to some serious testing.

 

[Gibsonian]

Should be interesting................

RCA 410's in there for drivers, right?

 

[laatsch55]

Yes cott, 410's as drivers.

Scott, you are getting a new Rev "C" board on me. I have ruined the traces on the CBE pads on the board, both sides. Repairs were made and it is no longer reliable. My humblest apologies.

 

[laatsch55]

I had some bias tranny problems with it when it was here before, and some this time and it was just too much for the traces. I figure I had soldered and desoldered that trio of pads 20 times. Just too muchj. Sorry again Scott.

 

[laatsch55]

Anmd the icing on the cake?? My solder sucker quit!!!!!!!!!!!!

 

[Gepetto]

That's the worst. The solder wick came out

 

[laatsch55]

Yep, when the solder sucker quits, the world comes to a screeching halt.

 

[Fairchild]

When any sucker quits it puts a damper on the world. lol
