Musical Fidelity A 1008 CD player

Hope someone out there is familiar with this player. Purchased this unit from a dealer who had this as a clearance item. Had unit for three days. On initial startup it worked well short of break in. After I changed to a different interconnect and repowered it up, the song progresses without sound for 35-35 seconds and then sound kicks in. The blue light for the power mains was already in the ready mode. Called dealer and asked if this was a defective unit. He told me that it is a muted while tube buffer stablizes. I didn't notice this when I first set it up, but may not have started it soon enough to notice the delay. I noticed this delay even when I use the solid state output, but he said it is muted because of the tube. Afterwards, it works fine.
Thanks
