no sound from my system. trying to determine if it is my amp or preamp. i have an aci titan powered sub hooked up tp a marsh preamp, a w4s amp connected to the other output. there is no sound from the sub or wfs amp. disconnected the w4s amp, no sound from the sub. preamp powers up, could it be bad tubes?
any suggestions would be appreciated.
thanks, drmike

Have you tried another source or a different input on the preamp?

Geez, no offence but whatever happened to "How and why our equipment works, construction, and DIY."
