Hi Matthias, I don't really think you are comparing like for like here! It is like saying "I have a 1982 Golf GTI, should I sell it and buy a 2008 Focus ST"?...
I own both.... you cant compare them...po8 is all modern with sequencer, lots of memory, complex sounds, polysix is simple, basic , good sounding sounds........
I've posted this before, but it might be time to repeat: I have programmed replacements available for the 8048 CPU chips -- $20 each. I also have the 8049...
... Any news on this clone project yet? I need one too and oldcrow doesn't seem to answer his emails I have sent. I noticed he had already done this before and...
Hi, After a bit of consideration I have decided to post the following. Over the last year I have been getting steadily more involved in analogue synth repairs....
Hi, The way I look at it is this. If I can use my skills to give something back to the community then this will be a good thing. Plus there is the pride...
As someone who's been repairing these boards for several years, let me say welcome. The more people we have doing this correctly, the better. My personal...
All Let me be the first of one of those "seem to be happy customers" to emphatically say that Andy is a first rate, extremely knowledgable, electronic god sent...
I think I've finally brought my P6 back from the grave after a big KLM367 rewiring job, and it's sounding great! I've followed the calibration procedure, and...
Hi Frank, I would venture that you may have not completed your mission with the KLM-367. I would go back and check the tracks and function of the logic at IC29...
Hi Andy Thanks for your help! ... I checked control lines P24 and P25 from CPU pins 35 and 36 to pin 5 of IC29 and IC35 (is this what you were referring to?),...
Hi Frank, No problem, we are always here to help, if we can! Actually, I do mean what I say. Look at the circuit diagram and carefully study IC29 and IC34. You...
Hi Andy ... Much appreciated! Actually, I do ... These both appear to be fine. ... No problem! I am an 'enthusiastic amateur' when it comes to electronics,...
Try to check 4xxx circuits on effects board... also very popular problem in korgs is that lm13600 got broken often. ne5517n is cheap and good replacement for...
Hello all, I have been working with a P6 that seems to be in good shape however it seems to be lacking in sound quality and dimension. I really am not a synth...
I don't have a great answer for you, but a couple of thoughts spring to mind. You may just be expecting too much from the synth. It is an old synth, and in my...
Hello, I'm new to this forum. My polysix has been sitting for years. Recently, I got ambitious and bought a lithium battery and holder to replace the old leaky...
Hi Rod, Welcome to the forum! As our esteemed collegues have pointed out you should re-visit the work carried out in and around IC31. Sometimes track...
I completely agree with this. When I repaired mine, there were traces which looked as though they had plenty of copper to conduct, but apparently the metal had...
hello, it's been awhile since my circuits courses in school - can anybody tell me exactly what purpose is served by removing c40 and replacing r91 with a...
Brian, The old battery was a nickel cadmium type and was rechargeable. The replacement which you are trying to fit is undoubtedly a lithium coin cell which...
Hi. We're looking to buy a Korg Polysix Factory MIDI kit, with or without the Polysix. Please email me at minime123 at onebox dot com if you've got a Polysix ...
All the patches are the same on boot up. I haven't bothered sticking a battery in this one because the problem exists where it simply won't save patches when...
Robert, I had similar problems in the past, however, in my case replacing the SRAM cured the fault. This was a new component and not old stock or something ...
At long last, my P6 is alive! Thanks to some help from Andy, for which I am extremely grateful, the effect problem was traced to IC7 and IC8, the NE570N...
Now that the effects board is back in action, my P6 is now 99% there at last! I just have to fit a new battery, load the factory presets and it should be...
