Schematic for Peavey PV215D, PV2015D
« on: February 02, 2021, 12:42:00 PM »
Howdy all.  I bought a broken Peavey PV215D (powered speaker system with two 15" speakers and a quasi-3-way output) ("does not pass signal", but found it really out blows fuse) and searched for an electrical schematic for it.  Peavey had not responded to my request in a week, so I went deep-diving in the Internet.

Attached is the schematic I found and downloaded (for free, although it says "Buy it").  If there is a problem with posting this here, please let me know.

In troubleshooting the powered speaker amplifier, I found so far that the power supply is the initial problem.  I found the -VCC side had a shorted FMG22R (dual "fast-acting" diode with common anode in TO220 type package).  I have one on order so I can see what else is wrong, if anything.  One of the two diodes in that package is a total short, and with that device removed from the board, the power supply caps both build up resistance (where the one on the -VCC was always 0 ohms with the device in the circuit).

The amp uses what they call class D amplification, and for the 700 watt rated output, doesn't seem too robust, so it must be very efficient.  (I hope the Peavey watts are as loud as the Fender watts, lol).

I post this in case anyone else needs this and to give back to this forum for the help I've gotten.
