Hi all,
I own a M400 #427. It is in need of restoration, and I am finally
ready to dig in. I have two sets of tapes, one in the 'tron itself
and one in a case.
>I also have the Muff Cover. (Oooooo ... squishy!)
And it will come in handy if you ever have to move it.
As far as tapes, is Kean the guy. What about Streetly? What are the
differences, if any.
Both supply tapes and frames. We Mellotronists are grateful that there are two parties who are willing to provide this service (competition is a good thing from our point of view) and we should support them both. I've only used Streetly's tapes, so I can't comment on DKs. I'd agree with Clay, that Streetly has a good offer for tapes right now (the ∗tape amnesty∗ thing). Half price for a replacment set on genuine vintage EMI stock (behaves very well in Mellotrons), any sounds you want. Note that you'll need to give up your current set to get this. I just used this EMI tape stock in my MKII with excellent results.
I'm in the US in New York. What about heads? Are
they available? Mine are good, but just wondering.
With all of the Mellotronists on this list, and all the playback heads out there in our 'trons (35 under each keyboard), I've never heard anyone say that they needed to replace a head. So, it's probably not a big issue. I'm sure that they would be available if you ever needed one.
More likely, you'd need to clean or replace pinch rollers, which can cause "wobblies" (excessive pitch variations in the sound). You can get pinch rollers from DK, and I think that Streetly may have some also. I can usually get any sticking pinch rollers going (spinning) by soaking the axles in isopropyl alcohol for about 30 seconds or so, then spinning them until dry. Actually replacing a pinch roller itself in the steel assembly is more difficult, and I've never tied it. If anyone has done this, I'd like to hear how it's done.
Are these new
electronic upgrades that Kean is offering good? What are the noticeable improvements?
Good question. Has anyone replaced their M400 parts with DKs new parts? I'm assuming that you are talking about the MKVI parts he is offering on his web site.
I could simply restore what I have now.
Sounds like a good plan of attack. If you have the old CMC-10 motor control board, you may consider upgrading to an SMS-2 (Streetly) or SMS-5 (Keene). This takes the whine out of the audio, if you have that problem, and makes it so you can play more notes at a time without having it going out of tune while holding the chord. Photos and descriptions of a CMC-10 replacement can be found on my web site by clicking the following link:

Finally, after doing these things, you'll need to adjust the pinch rollers and pressure pads. An excellent description on how to do this can be found on Norm Leete's web site. Click on the following link:

That should be enough for now, more questions coming.
Sometimes, playing the M400 is the best medicine. They seem to sound better the more that they are played.
Good luck, let us know how it goes.
Ken M.
