I can't find any schematics for the power supply etc. The only schematic I have found is for the preamp board(no voltages), which is not of much help cause I need to trouble shoot the power supply. If anyone has information, links to, or schematics they would like to share, I would be ever so grateful. Also if someone has this mixer and can take a few voltage measurements of the power transformer secondary AC voltage, that would be of great help, cause then I could calculated my way through the power supply if I know what the transformer is supposed to be putting out. This is old analog beast with spring reverb needs a second chance otherwise I will be parting it out. Here is a picture (from google images) of the mixer for reference. The schematics might quite possibly be missing 'the power supply'. But you have like 98% of the circuitry covered between those two schematics. It should be a relatively simple task to trace-out the remaining stuff. The power supply in that bad boy isn't likely to be anything exotic. Just a bridge rectifier, a monster-sized capacitor, and maybe a power resistor or two and probably some sort of thermal cut-off (likely located in the power transistors heatsink). Or try calling Peavey - They are really exceedingly helpful in tracking down old schematics! If the cap is leaking, obviously it needs replacing. Heck, that might be enough to get it working again! Caddx dl 900 windows software. The chance of a bad power transformer is very very small really. Of anything in there that's not likely to fail, the PT would be near the top of the list. Insofar as how much voltage the transformer should be putting out. You can figure it'll be something significantly less than 75V! (Because that's the rating on the bad cap) You can even estimate the voltage by taking the rated output power in the rated load, then apply ohms law (P=V^2/R. Rearranges to SQRT(P*R)=V). Whether or not underground, it needs to be housed in a pipe that is in order to prevent internal air, such as with a mechanical shutter kept closed most of the time but a used during the moments of firing to prevent loss of vacuum. By being mainly located slightly above, on or beneath the ground, a mass driver may be easier to maintain compared with many other structures of. A mass driver would accelerate a payload up to some high speed which would not be enough for orbit. The 40 per kilogram or less of projectiles launched at up to 9000 m/s velocity (if including extra for drag losses) towards is a few per kilogram if efficiencies are relatively high, which accordingly has been hypothesized to be under $1 of electrical energy cost per kilogram shipped to, though total costs would be far more than electricity alone. A mass driver on Earth would usually be a compromise system. Peavey Deca 700 Repair Manual DownloadThanks again Kyle. Great advice. I'm going to test and replace any bad caps in the power supply and then see where I'm at from there. Those damn 5000uf caps aren't cheap! I can't complain, I bought this mixer for $20. Most my experience has been with hand wired tube gear, so this is a good learning experience for me. Peavey Deca 700 Repair Manual PdfI'm not a seasoned tech, but have learned enough to know I have more to learn. I greatly appreciate the info and time supplied by guys like you who have lots of experience and knowledge. I started servicing my guitar tube amps about 2 years ago with the plans to become self sufficient and avoid bench fees(goal accomplished). I have fell in love with this work and it's my passion now. I have a few repairs and custom builds under my belt. At this point I want to learn and work hands on as much as I can, and would like to start a small business on the side doing repairs and custom builds.to fund more projects! I understand and practice all safety procedures EVERY time I perform any work or tests. I bought this mixer as is, the guy said it would not turn on. Basically dead. I turned in on with my current limiter and a variac. But it will not pass audio (had an ipod plugged into it). The is a steady hum at the speaker output. So I turned it off and tested the Main input cap which is badly leaking. I didn't properly spend much time with troubleshooting yet. So I stopped there. Although I did notice I wasn't getting any voltage on filter cap following the Bridge Rectifier. There was voltage on the Bridge Rectifier diodes though. I will spend more time on this with more methodical troubleshooting rather than random test like I've done so far, now that I have the schematic. Also, none of the LED indicators turn on. Thanks for your time, I will do as instructed if you are willing to proceed with helping. Agree and add: 1) build a lamp bulb limiter A 60W or 75W lamp will be fine. A real filament one of course, either the old type or the new semi high efficiency ones which have a small filament and transparent bulb inside a larger conventional glass one, not CFL or LED lamps. 2) you will get somewhat less than 120V on primary, measure voltages in the center tapped windings you found. I'd expect around 15+15VAC on the low power (preamp) ones (Or, Or+Wh, Or) and around 35+35VAC on the high power (main amp) ones (R, R+W, R) so some 30VAC and 70VAC end to end respectively. Limiter lamp glowing red or dull orange= fine Bright orange/yellow/white= different degrees of trouble. Post results. Sorry for the delay. I was away this weekend. (I don't have a smart phone, yeah really, so I can only access the internet at home) Anyways. I will have some time today and this week in the evening after work to get back on this. I will report back with COMPLETE information and correct the false results I posted about the Transformer originally. Peavey Deca 700 Repair Manual FreeI sent an email to Peavey before I started this thread asking for the schematics. They just got back to me and with the FULL set of schematics and PCB board/component layouts! Those guys are great! The transformer schematic is in there too. I re tested the transformer unloaded and loaded and can confirm it is in normal working order matching the schematic. I have do have a dim bulb limiter set up in series with my variac and have been using when powering the mixer up. Magic stomp patch list.
