Just wondering if any of you guys has experienced this problem? Ive been through the process of elimination and come to the conclusion it doesnt like the PS. Tried different rca leads and footswitch's and it still happens. What I have noticed is, once it starts really bogging down, if I unplug the machine and run on a different set up for a second or two, and then go back to the critical, its ok for a short while, but then reverts back to running weak??I run it at around 6.5 to 7 volts and wanted to use it for mostly black and grey. I know its not a faulty ps as its less than a year old, and runs all my other machines including a Rotary Works.Just wondered if there was a known issue with using this machine, with this particular PS.Cheers in advance for any help.
