Just In Case's PL 400 to Wopl Conversion

[Northwinds]

What does Jani use to clean them up Lee? I have some industrial stainless steel cleaner that I use, does not hurt the lettering but does not always take off that weird haze you see on them sometimes

Jani says Flitz....

Lee, How did you get started doing this?

Also I read where an upside down faceplate identified a rare factory variant. I could be rich! lol.

My Spec 2 went into protection mode in 2008 . So I bought a few broken PL 400's off e-bay, and with a lot of help from EW, mark the fixer, Don Imlay and Joe.....I eventually learned how to swap out parts.

How does it work with gummed up nicotine?

 

[laatsch55]

And yes, I did get my Spec 2 restored and went on to fix a few more. I did a lot of reading, utterly destroyed a driver board for an L85 V Luxman ( which belonged to someone else and wound up buying cause I couldn't fix it) , and have probably drove Joe nuts in the last few years with questions I should have known the answers to working on the stuff I was trying to fix. I was in over my head a lot, but it eventually started to make sense...

Good. She uses a little battery powered scrubber with a gentle brush attachment.

 

[laatsch55]

Longest name I've seen on the signature tag.....

 

[laatsch55]

Time to start going back together with it...

 

[laatsch55]

Ac in.....

 

[laatsch55]

New Speaker posts, new RCA jacks, and new 50 amp bridge rectifier, properly bypassed.

 

[laatsch55]

This is an early 400, so the bias transistor holes have to be relocated to accept the backplanes. For anyone interested the center to center measurment from the upper pilot hole to the bias tranny hole is 2-11/32nds....

 

[laatsch55]

BR soldered up with power wire for the DCP{. Bias holes in....

 

[laatsch55]

Standoffs, bushings and pilots in...

 

[laatsch55]

Backplanes in....

 

[laatsch55]

The old fuseholders were getting pretty flaky, sooooo, in with new rail fuseholders....

Lee , I was looking at the picture of the rectifier and have a question. The green wires I'm guessing go to the DCP but what are the shielded wires for?

 

[laatsch55]

The green wires go to the unfused +/- rail connections on the caps. The shielded wires are the + AC secondary voltage and ground to feed the DC protect relay voltage.

 

[Steve K]

Ok thanks.

 

[laatsch55]

Caps in....
