PL-400 DCP and WO light board

[AngrySailor]

Yes, if you leave the jumper in position 2-3 and resistors uninstalled, it is stock.

Hardware store closed or I was going to pick up a socket and plug ends... had to MacGuyver it for today.

Not standard rack spacing. None of the PLs were.

Nice job on the light board Joe, it fit like a glove! And thank you Lee, same with the DCP, easy install. Linda and I appreciate the other goodies you sent along also!

I guess I’ll hook her up temporarily in the house, I have some vintage Sansui speakers and a pre amp I can use for now until I finish the big build and the new entertainment Center.

 

[AngrySailor]

Hooked up my sine generator. I’ll need to feed it through a pre amp. I can only get ~30vac with out more input.

 

[laatsch55]

What is your max input now?

 

[laatsch55]

Did you change resistors on the DCP?

 

[AngrySailor]

Did you change resistors on the DCP?

Yessir, resistors changed.

I was only able to get ~33vac with my generator straight in. And I can only get down to 20hz... not sure that will trip the DCP?

 

[AngrySailor]

Never thought I’d take a die grinder to a PL but I just did. Tapped the rack handle holes 1/4-20 because a new hole was easier to find than new bolts... all buttoned up. If you wanted to get right fussy, you can see a little of the old holes underneath the rack handles... I could make a trim piece to go between the face plate and handles to finish it perfect. Maybe some day. You really have to look from the right angle to see it.

 

[laatsch55]

DCP shouldnt trip it till 5hz or so, or a really big peak at 10 hz or so.
I'm diggin the rack handles on the 400!!

 

[AngrySailor]

Get it before YouTube Copy right strikes it! No pre amp, POS doesn’t want to work.

 

[laatsch55]

Ahhh....she's an 8 finner...sounding good..

 

[laatsch55]

What was the voltage of your input when you had 33 volts out?

Sheiit, couldn’t tell ya generator not that fancy and I didn’t measure. Meters were about 0dB though.

 

[AngrySailor]

Need some tone control... she’s a little middy without a pre amp. She’s quiet with no input. Sounds balanced. Meters swinging pretty even. Yeah they’re mostly eye candy but damn they’re sexy!

 

[laatsch55]

Straight outta the CD player eh??

 

[laatsch55]

Haven't checked bias yet?

 

[AngrySailor]

Fack, I meant to do that while her top was down... I’m new to this amplifier stuff so go easy on me... I’ll pull the cover and check. She’s running cool for last 45mins. Last time I had a bias problem things got toasty fast!

 

[laatsch55]

If she's running cool it's not to high anyway..

 

[AngrySailor]

If she's running cool it's not to high anyway..

560mV right
570mV left

 

[laatsch55]

That's pretty dsmn high. Where are you checking that?
