arp 2600 reverb send/return levels

2006-02-24 by doktazaus

Hi, I'm new to this group...

Does anyone know the procedure to turn up the level of the reverb send and turn down the 
return level?  Looks like it will involve changing out some resistors.  This is supposed to 
reduce the noise in the reverb circuit.  Also, can anyone advise on the usefulness of changing 
out all of the lm301's on the 4-2 board and replacing with high slew rate chips?

Thanks in advance for any help...
