Thanks, I gotta stop breaking stuff and tear down, clean up my wiring and build a decent entertainment center for the stuff. Was just digging through the stuff you sent me raping some parts and reminded me I have to full comp Tim, there’s also a 700b in the works...

She’s alive... got original PL emitter resistors one channel and I still need to get a few resistors to bring things right back to spec.

Looking at swapping crossovers with pops... his is stereo 3 way which will allow me to use both Tim and Linda along with the monster carver. Hoping to get Linda patched up tonight enough to test drive then I’ll have to modify the speaker jacks on the three way cabinets to separate the 15’s from...

Edit/caveat: ENTIRELY MY FAULT :violent2:

Thanks Joe, I’ll be ordering stuff for a 700b soon, your kits for Tim and Linda had a few extra goodies that really helped. Couple extra diodes and resistors but man, did I ever blow this up...:oops:

Lots of help available here...

Thanks Lee. I’ve actually enjoyed fucking up as It forces me to learn much more about the driver board. Couple questions... r9&10 1 ohm resistor on the back plane, it was in Kohm range so I bridged a 10 ohm across. Replaced blown emitter resistors on xq 5&6 with original pl400 emitter resistors...

Geez, when I edit that post I changed a couple sentences around and forgot to mention Grapplesaw, he was a HUGE help with the diagnostics and repair. Sorry you got lost out of the original post!

I was waiting to post until I got things figured out but I blew Linda’s right channel up doing some testing... drove the channel to near clipping and was taking some voltage readings in and out as I have an imbalance somewhere in my system and wanted to eliminate any possibility of the...

Not very helpful but I’d select all options... awesome to have a product like this in the works Joe.

They don’t photo well at all. Look much better in person...

Had a bad compression driver in the left cabinet. Was working but half melted VC and tone was way off. Speakers sound correct now, think I have issues with other components in the signal path. Did some signal generator testing. I’m going to do that again and write out the results to post later...

I should have measured while it was apart but what are the two meter ranges available by jumper and which position is which? Can’t find my original documents for the light board. I cranked it up a bit and hardly got the meters moving before my left channel (probably speaker issue) shut me down...

I did move the rectifier as you say, the one meter terminal was still VERY close to the plate (maybe 1/32”) so I just made a little extra room. I blew up one 400/1 meter already doing something stupid and took probably ten years to find another (thanks Lee).

She’s alive! No issues getting it together other than having to grind the capacitor hold down plate to clear the meter stud. I’ve got to check my left speaker and crossover. Somethings not right but Tim was acting goofy on the left also so I doubt it the amp. Haven’t listened to her much as I...

Some reading I did a long ways back specified air core inductors had desirable characteristics for crossover application other than being more expensive($7 ffs) and larger physically. There’s a 0.61mH near the top of the page I posted.

Go easy on me, I probably misspoke and otherwise fucked up but at then end of the day the smoke stayed in. Just have to harness up the wires neat, add Don’s DCP back in and button her up.

Hibernating...

Linda’s coming to life. Passed all tests with drivers installed today. I’m busy and grumpy. I said grumpy, not angry so that’s an improvement...
