Wow 8....That's nice I have a 2year old daughter and another on the way..

If you can check the power supply for the correct voltages...It's a bit tricky if you have no experience.

Yes...I think the RAM or a chip that controls them....I can't confirm this without a scope.

What do you think Mr Rhino..

I wonder if the ram has gone down....?

I have had another look...When I go to program a pattern it just locks up even on the presets.
It has to be switched off and on again.

I don't have a scope to see those pulses.

Cheers again Rhino...I will report back when I have news.

Thanks Rhino....I need to look at it first but just maybe a logic chip or bad connection..

What do you think..?

The battery checked out fine....I need to investigate the real problem after i fix my polivox.

Mine also locks up but the battery was fine...I am going to restore mine but i wonder what else could go wrong..?

Sorry..FARNELL ...

Farnel stock it..

I use SCG electrolube....It's good.

The power supply is now fixed and the filter is working..

The next problem....The lfo is bleeding through the audio..I get constant modulation that tracks the keys..?

Please where next...???

I hope it's not too bad..But first the power supply and see what happens.

The guy I bought it from said it just stopped working.

We shall see....Thank you..

Thank you for the info....I am going to find replacements for V2 and V3 but I can't get the parts until monday.

I am hoping the power supply is the solution...After 3 years I can hear what it sounds like.


Again many thanks for this help..
