Audible Illusions Modulus 3A troubles
Just purchased a used Audible Illusions Modulus 3A preamp for my system but only getting very very faint sound when turned all the way up. Plus the very very faint sound is very fuzzy as well.
I popped off the top & re-seated the 4 tubes but that was no help.
My 2 amps are both rated at 50k ohms input sensitivity, so this is the right preamp for them at around 1.2k ohms output sensitivity, running a biamp configuration. AI documentations confirms this.
I've tried each amp on its own, using both output RCAs on the preamp, to no avail.
How to tell what is wrong...looking into the return policy, but at least the shipment was insured.
Any ideas?
Thanks-Kevin
yes, i've been through each setting, each input (they all come through in the same very very quiet manner), even to the point of adjusting the jumper switches behind the tubes - they also had no effect. Is there a way to prove that it is the tube? Is it ok to swap them around? I've heard one should keep the tubes in the same place. |
