Yamaha CS80

Hi guys,

I have recently managaed to fix all my faulty on my CS80, and have
talked to quite a few people about my faults and symptoms along the
way. A big thanks to a couple of them who pop along here now and then!!

It has taken me just about a year - and I found out quite a lot.

One thing that has been sitting at the back of my mind is the fact
that most component failure happens when the unit is switched on. The
surge of power or whatever will take out any weak components first..
(or even contribute to shortening component life..?) I heard a lot of
engineers use a power transformer on which they can slowly wind up the
voltage, checking things as they do - so under *fault conditions* key
components won't instantly blow, and there is a chance reducing the
volts if a symptom shows itself as the voltage is increased.

Now, my question is - would it make sense to have your CS80 on the end
of one of these power transformers constantly...? that way, even when
all is well and working fine, you can ease to power on gently whenever
you turn her on - thus hopefully, prolonging component life..??

Would this be an idea worth considering?

Cheers, and Merry Christmas to all.
TOM

i cannot see how running a cs-80 on a variac would be a bad idea. it seems very sensible.

i have heard that one of the issues that some of the 60's valve limiters had(fairchild,ba-6a,etc)was that the input transformer put out a higher than spec-ed voltage, which apparently resulted in a great tone, bbut also shorter lifespan of tubes as well as actual units. when brought down to specified voltage, they apparently run much better. i have several units that power up just fine on PSU's that are slightly below design voltage, and run better on them(cheaper moogs). should we all be making the switch for the life of the machines? assuming it works properly, could running a cs-80 at 105-110VAC be a bad idea? -rj

The CS-80 of course was the main synth but according to Sound on Sound
a CS-40 mono synth was used also
Can anyone please tell me what the CS-40 mono synth was used for in
the Blade Runner soundtrack--eg parts

thanks David

Surely overkill --why not just replace filter caps?

Probably additional sound effects (think Leon´s interview at Tyrell, before he shoots down Holden) and noise drones in the background.

Never had my hands on a synthesiser other than an EMS that could produce such an awful plethora of noise. If it weren´t that big, I´d probably own one.

sorry, but while we are on the subject, i recently brought a cs-40m back to life. she's 100%, with all PSU caps, and several other boards tants, replaced. tuned and calibrated, cosmetically beautiful. as its 1 of 3 i have here, i would be interested in a trade for another analog. jupiter 4 being 1st on my list, but open to something else possibly as well. email me off-list if interested. thanks-rj

Hi rj
How does it compare with a CS-70M. I have a CS-50 and after reading that CS40M was used on Blade Runner I would like to get one
I had a CS-70M about 5 years ago and regret selling that--people tell me that CS40M is a better machine than CS-70M though?
I may be interested in buy your CS-40M outright
cheers Dave
