Hello Niels,

 NP>  yeah...  Got circuits for quite a few of them.

 NP>  Are they single or double spring setups ?

Both types, 6 of each from memory.

 NP>  What do you intend using them for????

Mainly guitars, and a little vocal work too, for the appropriate
musical styles...

 NP>  Do you want Transistor or Valve circuits :-)

Transistor - I'll adapt them to IC designs.

 NP>  I just need some time to do a search for the manuals and do some
 NP>  photocopies.

 NP>  Is there a Fax number to send them to ???

Hmmmm... I've got a Faxmodem, but never used the fax side of it.

I wasn't really after exact circuits anyway, just an idea of
impedances and equalisation values and the like, as I'll be using
modern and familiar components...

 NP>  I saw someone quote that they were only used with an Auxirally Reverb
 NP>  Amp but that was mostly on the early Hammond Organ models. All the

 NP> in the Yamaha EM series PA mixers
 NP> (I KNOW where those manuals are)

If you have got an exact model no, I can prolly chase up a circuit
locally.  It's only a sparetime thing - so no hurry to get this one
finished!

I'd have ditched the things, only that they are beautifully made
(and must have cost a small fortune in their day) and it would
be a shame to see them go to waste...

Regards,
Chris.
