would anybody happen to know where to get the push buttons for the x-overs? in the first pic you can see one fully intact button & 2 broken buttons with wires soldered across the contacts. i picked it up from a guy a few months back on craigslist & i haven't even checked it out yet but i noticed the buttons missing. it's not absolutely nessecery but i would to have the amp in as nice condition as possible (for my collection).
thanks |

Would this work?
http://spec.e-switch.com/Q-D/Q960000E.pdf Digi-Key - EG2655-ND (Manufacturer - PBH2UEENAGX) Or this? Digi-Key - 401-1192-ND (Manufacturer - PHA2UEE)

I used these PBH2UEEKZXNAG1RBLK from Mouser in a P840 and P4100 before. I just removed the metal shield.

Thanks for the tip on just the caps, I find these missing often. As a side note, the ones from Mouser include the caps in the price, I didn't see that mentioned as included on Digikey's site.

as of now im not getting any output from the amp. the power supply seems to be running fine and all the outputs are getting rail voltage but no signal. before i go any deeper ill probably wait on the new switches to get in and installed.
does anybody know if ads is affiliated with orion in any way? i just noticed a piece of an orion lable on the inner heat sink, it appears to be insulating the led leads from the heatsink. |

From the Directed site:
In 1994, Orion merged with ADS Technologies, pooling the resources of some of the leading home audio and professional equipment engineers in the world, resulting in products such as the DEQ30--the industry's first fully digital, standalone 30 band equalizer.

Actually, I wasn't entirely sure until I looked it up.

Remove the jumper wire it looks incorrect. The switch when pushed in (turning Crossover ON if I remember right) make contact like the first pic. The switch when out (turning crossover OFF) makes contact like the second. I may have it backward, but the wire should NOT jump accross the rows.
