Current Lover clock frequency

I tried to search for the info but could not find anything. What is the correct frequency (to be close to the original electric mistress) the clock should be biased to?

I dialed it in to work over a good range but I was wondering to what range the original would be set to.
Note that I am using a MN3027, not sure if the frequency is to be set differently with a MN3007.

For either 3007 or 3207 you need to double the original clock frequency as we are now using twice as many stages.

I however can't find the original V6 set up procedure and the best I can give is to set the bottom frequency between 40 - 70KHz to taste (originally 20 - 35KHz). Really need someone with an original units measurements.

I do not know about the EM V6 but..... the DEM V4/5 (with the RD5106 BBD) had a clock of 40KHz-520KHz.

Hope that helps  ;)

Thanks guys :-)
According to the datasheet a RD5106 is 256 stages. Does that mean that I would have to quadruple the frequency then?

There is a reason why the RD5106 could be used in place of 512-stage BBDs (SAD512D was commonly replaced) however, I don't remember the explanation as to why  :-[ Had something to do with the way it internally generated clock pulses.
