Members Muz Posted December 6, 2006 Members Share Posted December 6, 2006 A friend of mine had this keyboard for many years, virtually untouched. He's giving it to me for a good "deal." (compared to current Ebay prices). It appears to be in good condition and I'm psyched. But I need a fuse, I think. Look at the 3rd pic at the empty square under the power switch. Where to get one and what part number, anyone? Link to comment Share on other sites More sharing options...
Members sleepykeith Posted December 6, 2006 Members Share Posted December 6, 2006 it's possible any electronics repair shop could help you, otherwise try these folks.http://www.winecountrysequential.com/ Link to comment Share on other sites More sharing options...
Members clusterchord Posted December 6, 2006 Members Share Posted December 6, 2006 wow, it looks gorgeous. the panel, wood, everything.. nice catch. i always digged the version of rev3 with this reddish shade of wood.. not all of rev3's have this. as for your question, perhaps you should google for Rev3 service manual, i've seen it online many times, but can't remember the URL for the love of it.. it should have all data u could possibly need. or, you can contact greg at www.analogsynthservice.com and ask. he is a SCI tech.

Members The Real MC Posted December 7, 2006 Members Share Posted December 7, 2006 A fuse for a Prophet-5? Sounds like a fair trade to me :D Link to comment Share on other sites More sharing options...
Members bruto Posted December 7, 2006 Members Share Posted December 7, 2006 Man that's nice. Congrats! Post a demo when you get it going. Link to comment Share on other sites More sharing options...
Members flattop Posted December 7, 2006 Members Share Posted December 7, 2006 All Rev 2's and 3's were Walnut. You should be able to find fuseholders at Mouser, Digi-key, or the like. You will probably have to purchase the entire fuseholder though you only need the cap. Wes TaggartAnalogicshttp://www.analogics.org/ Link to comment Share on other sites More sharing options...
Members Muz Posted December 8, 2006 Author Members Share Posted December 8, 2006 Thanks for your help guys. Greg at www.analogsynthservice.com answered my emails and I ordered a fuse from one place and a cap from another, hopefully it will work! In case anyone's curious, it's a 1 1/4 inch 3/4 amp slow blow fuse. Also I was able to get free manuals from here http://www.analoghell.com/studio/index.cfm?fuse=Downloads I can't wait to play this thing! I'll post some demos.

Members Muz Posted December 13, 2006 Author Members Share Posted December 13, 2006 After a slight debacle with one online store sending me the wrong part entirely, I got the correct fuse, and was able to power it on. Now the bad news. Something is definitely not right with this thing. First off, all the lights (for those buttons selected as on for a given preset) blink and the preset number display is all messed up. And the sound is messed up. I hadn't paid my friend yet in case of this. I have a good keyboard tech who makes house calls but I don't think he has a lot of experience with Prophet 5s. I'm probably going to have him look at it anyways. Anyone familiar with these symptoms and their prescribed cost? Link to comment Share on other sites More sharing options...
Members flattop Posted December 13, 2006 Members Share Posted December 13, 2006 Try working all the pots a lot, especially the higher resolution ones in the filter and envelope sections. Issues such as this can be caused by the CPU trying to read pot values when the pots are extremely dirty. If this works, the instrument will probably still need an overhaul. Contrary to popular belief, long term storage (I'm talking decades) is not good for electronics.

Members Muz Posted December 14, 2006 Author Members Share Posted December 14, 2006 THanks, I'll try that. Could you be more specific when you say 'overhaul?' Link to comment Share on other sites More sharing options...
Members flattop Posted December 14, 2006 Members Share Posted December 14, 2006 General cleaning, rebuild the power supply, replace caps, calibration, etc... This is excluding any electronic issues like voices not tuning/working, etc... Instruments that sit for extended periods of time often develop issues from non-use. Caps dry out, tolerances change, contacts corrode, switches stick, etc... A lot of excetraing. You should keep all of this in mind when purchasing this instrument. Instrument looks in good cosmetic shape (aside from where the owner used duct tape to keep the fuseholder cap in place), so it may very well be worth the investment.

A lot of analogs don't really do anything unless the internal battery is working. You might want to look at that first. It'll cost you all but $5!

Members flattop Posted December 14, 2006 Members Share Posted December 14, 2006 The battery deals with basically one thing, supplying the memory with power when the unit is turned off. Symptom of bad battery is scrambled patches. A bad battery will rarely keep an instrument from functioning. A good way to tell is turn on the unit and if the patches make no sense, put the unit in manual mode. Dial up what you would consider a very basic patch. One oscillator, wide open filter, organ type envelopes, all modulation off. If the unit performs as you expect it to, save the patch. Turn the unit off and go have lunch. After lunch, turn on the unit and bring up the patch. If it's gone, you need a new battery. There are exceptions to all examples, such as above, but this one can be applied about 95-98% of the time.
